The underlying information was acquired from telecommunications carriers holding numbering resources and was analyzed as part of our ongoing assessment of the efficacy of numbering resource optimization measures prescribed by the Commission’s Numbering Resource Optimization (NRO) Orders. 2 Findings As of June 30, 2010: ? Overall, 47.9% of all telephone numbe rs were assigned to end users. ? The overall utilization rate for Incumbent Local Exchange Carriers (LECs) was 47.1%, down from 47.3% six months earlier. ? The overall utilization rate for Mobile Wirel ess carriers was 66.8%, up from 66.7% six months earlier. ? The overall utilization rate for Competitive LECs was 33.3%, down from 34.0% six months earlier. ? Thousands-block pooling has made it unnecessary to distribute about 483 million telephone numbers. ? Since wireless number portability began on November 24, 2003, wireline customers have moved over 94 million telephone numbers to new wireline carriers and wireless customers moved almost 87 million telephone numbers to new wireless carriers. Over 4 million wireline telephone numbers have been moved to wireless carriers and about 275,000 wireless numbers have been moved to wireline carriers. ? In the second quarter of 2010, carriers returned 670,000 telephone numbers to the NANPA. 1 The previous edition of this report, with data as of December 31, 2009, was released in January 2011. 2 See Numbering Resource Optimization, CC Docket No. 99-200, Report and Order and Further Notice of Proposed Rulemaking, 15 FCC Rcd 7574 (2000) (First NRO Order); Numbering Resource Optimization, CC Docket Nos. 99- 200, 96-98, Second Report and Order, Order on Reconsideration in CC Docket No. 96-98 and CC Docket No. 99- 200, and Second Further Notice of Proposed Rulemaking in CC Docket No. 99-200, 16 FCC Rcd 306 (2000) (Second NRO Order); Numbering Resource Optimization, CC Docket Nos. 99-200, 96-98, 95-116, Third Report and Order and Second Order on Reconsideration in CC Docket No. 96-98 and CC Docket No. 99-200, 17 FCC Rcd 252 (2001) (Third NRO Order); Numbering Resource Optimization, CC Docket Nos. 99-200, 96-98, 95-116, Fourth Report and Order in CC Docket No. 99-200 and CC Docket No. 95-116, and Fourth Further Notice of Proposed Rulemaking in CC Docket No. 99-200, 18 FCC Rcd 12472 (2003) (Fourth NRO Order). U.S. Federal Communications Commission Numbering Resource Utilization in the United States 1 ? In the third quarter of 2010, carriers returned 770,000 telephone numbers to the NANPA. Background The United States uses ten-digit telephone numbers, which are organized in accordance with the North American Numbering Plan (NANP).3 The NANP divides the country into separate geographic areas called numbering plan areas (NPAs), more commonly called area codes. Calls between these areas are generally dialed using the three-digit area code, followed by a seven-digit local telephone number. When the NANP was established in 1947, only 78 area codes were assigned to telecommunications carriers in the United States. Only 36 new codes were added through 1989. But the rate of activation increased dramatically in the 1990s, when 109 new area codes were activated.4 Because the remaining supply of unassigned area codes was diminishing, and because a premature exhaust of area codes imposes significant costs on consumers, the Commission in 1999 initiated a proceeding to ensure that the limited numbering resources are used efficiently and thereby slow telephone number exhaust. In the First NRO Order, in 2000, the Commission established the requirement that telecommunications carriers controlling numbering resources for the purpose of providing services to their customers are required to file data on numbering resource utilization and forecasts twice a year. Utilization data as of December 31 are due to the North American Numbering Plan Administrator (NANPA) by February 1, and utilization da ta as of June 30 are due by August 1.5 The data are submitted using FCC Form 502, the Numbering Resource Utilization/Forecast (NRUF) form. 6 The NANPA compiles the submitted NRUF information into a database and provides that database to the Commission. The new NRUF-based information in this report is number utilization as of June 30, 2010. The information in this report reflects all submissions and corrections received by the NANPA through October 13, 2010. 7 Historically, local telephone companies received geographic numbers in blocks of 10,000. These ten-thousands blocks of numbers are often called NX Xs, or central office codes, and are identifiable as the first three digits of a seven-digit telephone number.8 To improve the efficiency with which numbers are used, the Commission’s NRO Orders establishe d “thousands-block number pooling,” where an NXX is broken into ten sequential blocks of 1,000 numbers.9 Carriers may then be required to donate unused or underutilized blocks to the Pooling Administrator, which then assigns those thousands-blocks to other 3 The North American Numbering Plan is used in the United States and its territories, and in Canada, Bermuda, and many Caribbean nations, including Anguilla, Antigua and Barbuda, the Bahamas, Barbados, British Virgin Islands, Cayman Islands, Dominica, Dominican Republic, Grenada, Jamaica, Montserrat, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, Trinidad and Tobago, and the Turks and Caicos Islands. The data contained in this report are all limited to the United States and its overseas territories. 4 A database containing information about each area code is available at http://www.nanpa.com/npa/allnpas.zip . 5 First NRO Order, 15 FCC Rcd at 7603, para. 67. The NANPA currently is NeuStar, Inc. 6 FCC Form 502 and most other FCC forms can be downloaded via http://www.fcc.gov/formpage.html, 7 The NANPA’s database is continually updated because not all carriers file by the prescribed date, and because carriers sometimes file updated information throughout the year. 8 That is, a ten-thousands block is the block of 10,000 telephone numbers that have the same area code and the same NXX. 9 Pooling for wireline and wireless carriers started in November 2002. For a discussion of this requirement, see Fourth NRO Order, 18 FCC Rcd at 12474-77, paras. 5–14. U.S. Federal Communications Commission Numbering Resource Utilization in the United States 2 carriers in need of numbers.10 This effectively allows the assignment of numbers in blocks of 1,000 rather than 10,000. Most carriers are required to report their number utilization information at the thousands- block level so that the Commission can evaluate the efficacy of telephone number pooling. However, carriers that meet the statutory definition of “rural telephone company” 11 and operate in non-pooling areas submit their number utilization information at the ten-thousands block (NXX) level. In this report, we present utilizati on data for four types of carriers:12 ? Incumbent LECs ? Competitive LECs ? Mobile Wireless Carriers ? Paging Carriers Carriers report on numbering resources in the following six categories: ? Assigned ? Intermediate ? Reserved ? Aging ? Administrative ? Available An assigned number is one that is in use by an end-user customer. Intermediate numbers are those that one carrier has made available for use by another carrier (or to a non-carrier) so that the numbers may then be assigned to an end user. Reserved numbers are those that are being held by the service provider at the request of an end user for future use. Aging numbers are those that are being held out of use by the carrier for a period of time after the end user that last used them discontinues service. Administrative numbers include test numbers and other numbers used for network management purposes. Available numbers are numbers that are generally available for assignment to customers.13 Some carriers receive telephone numbers from other carriers. When this occurs, the carrier that received its numbers from another carrier (as opposed to directly from the NANPA) is required to report utilization data for those numbers, and to mark those numbers as having been received from other carriers.14 10 The current Pooling Administrator is NeuStar, Inc., which is also the NANPA. 11 See 47 U.S.C. § 153(37). 12 Carriers classified themselves in a variety of ways on their NRUF forms. With one exception, each carrier type was aggregated into one of these four categories for the purposes of this report. The exception involves carriers calling themselves interexchange carriers. These carriers reported data for area codes 500 and 900, which are summarized in Table 10 of this report. Therefore, there was no need to classify interexchange carriers as one of the four carrier types listed above. Also, carriers may provide multiple types of services but report using a single operating company number (OCN). Where this occurs, this may cause a problem because carriers must indicate only their primary line of business on the NRUF form. Thus, for example, there is some potential that some numbers are classified as mobile wireless but are really used for paging. Only small carriers seem to do this, so the effects of this misclassification should be minor. 13 For precise definitions of these categories, see 47 C.F.R. § 52.15. 14 This means that sometimes more than one carrier can report utilization data for the same thousands-block (or ten-thousands block). The NRUF form contains separate sections for reporting utilization data for numbers received from another carrier and numbers received directly from the NANPA. Some carriers that receive numbers only U.S. Federal Communications Commission Numbering Resource Utilization in the United States 3 The vast majority of numbering resources reported were part of geographic area codes. That is, the numbers were part of area codes that are associated with specific regions of the United States or another country. For instance, area code 406 is associated with Montana, and area code 506 is associated with New Brunswick, Canada. Carriers are also required to report on utilization of some non-geographic area codes, such as 500 numbers and 900 numbers (which are described later in this report). Carriers use other types of non-geographic numbering resources as well: millions of numbers are used to provide toll-free services using non-geographic area codes such as 800, 888, 877 and 866. These numbering resources are managed separately. Analysis and Results Table 1 shows the total quantity of telephone numbers reported by telecommunications carriers and the number of ten-thousands blocks (NXXs) that were reported as of June 30, 2010. Table 1 also shows the quantity of telephone numbers that carriers reported for each of the six categories described above. The percentages for each of the six categories are provided as well. Carriers reported usage data on 142,625 NXXs. This is up from the 141,738 NXXs in the previous filing (data as of December 31, 2009). As the NANPA calculates that 144,692 NXXs have been assigned to U.S. carriers,15 this round of submissions appears to have garnered usable information on over 98% of the numbering resources assigned to carrier s in the United States. However, although the reporting level is high, many carriers had not provided usable utilization data by October 13, 2010, which was the cut-off date for inclusion in this report. Carriers filing NRUF forms reported that about 677 million telephone numbers were assigned to end users, and that 643 million were available for assignment. These 643 million available numbers do not include any telephone numbers in NXXs that had not yet been assigned to a carrier. As more NXXs are assigned to carriers by the NANPA, and more area codes are opened, more numbers will become available. Intermediate, reserved, aging and administrative categories collectively account for another 94 million telephone numbers of the NXXs assigned to ca rriers. The quantity of incumbent LEC assigned numbers is down slightly, reflecting the decreasing number of incumbent LEC lines.16 The quantity of mobile wireless assigned numbers is up, reflecting that sector’s growth. The quantity of CLEC assigned numbers continues to rise, in part, because of telephone service provided through voice over Internet protocol (VoIP). Table 2 presents statistics for numbers located in ten-thousands blocks for which carriers must report the utilization information at the thousands-block level. As previously explained, carriers that do not meet the statutory definition of a rural carrier are required to report in this manner. Table 3 presents statistics for rural carriers, which are required to report only at the ten-thousands block level.17 As might be expected, overall utilization rates are lower in rural areas (about 14% of from other carriers use the incorrect section of the form, however, so within the database it can appear that more than one carrier reported data for the same block of numbers. 15 The NANPA lists the codes that have been issued on its website at: http://www.nanpa.com/reports/reports_cocodes_assign.html. 16 See Table 1 of the most recent Local Telephone Competition report at http://www.fcc.gov/wcb/iatd/comp.html. 17 See First NRO Order, 15 FCC Rcd at 7604-05, para. 71. A small number of rural carriers may operate in areas with pooling. As all carriers in pooling areas are required to report at the thousands-block level, rural carriers in pooling areas, if any, should be included in Table 2 rather than Table 3. U.S. Federal Communications Commission Numbering Resource Utilization in the United States 4 telephone numbers are assigned to end users) than in more urban areas (about 50% of telephone numbers are assigned to end users). Table 4 shows utilization statistics on a state-by-state basis. As might be expected, states that are relatively rural and have low population densities have a lower percentage of numbers that have been assigned to end-user customers than in more urban, populous states. Again, carriers report for only those numbers that have been assigned to them, so the quantity of available numbers does not include any of the NXXs that had not yet been assigned to a carrier. Table 5 shows the number of carriers reporting telephone number utilization data for each state. Carriers are required to report their NRUF data at the OCN level.18 Carriers typically obtain one or more OCNs per state in which they operate. The number of carriers in each state is determined by counting the number of OCNs reported in each state. Table 6 shows utilization statistics on an area code -by-area code basis. The table also shows the total number of OCNs reported in each area code. Again, carriers report for only those numbers that have been assigned to them, so the quantity of available numbers does not include any of the NXXs in the state that had not yet been assigned to a carrier. Table 7 shows actual quantities of assigned, aging, and available numbers for wireline carriers (incumbent LECs and CLECs) and for mobile wireless carriers on an area code-by-area code basis. The information in Table 7 is useful for at least two reasons. First, while there is no information on the number of working telephone lines in each area code, Table 7 provides at least some indication of what these numbers are. For several reasons, however, the number of working lines per area code cannot be perfectly divined from this information. Although mobile wireless carriers typically assign one geographic telephone number to each mobile wireless telephone, some also assign telephone numbers to other wireless devices. Similarly, wireline subscribers do not necessarily match the number of wireline phone numbers. For instance some wireline customers want multiple telephone numbers associated with a smaller number of lines. This is common when the customer has a PBX. Other wireline customers, especially those expecting many inbound calls, such as to a help line, want a single telephone number that serves many lines. Thus, the quantity of telephone numbers in an area code provides only a rough guide to the number of lines in service in each area code. Second, the information in Table 7 provides the only information available for examining churn.19 After a customer disconnects from a carrier’s network and chooses not to port the number to another carrier, that carrier will hold that number out of circulation (“age” the number) for up to ninety days if the customer was a residential subscriber, and up to one year if the customer was a business subscriber. Therefore, the quantity of aging numbers gives some indication of the number of customers that have disconnected from the carrier’s network in the previous three months to a year. For several reasons, aging numbers, however, do not give a perfect indication of churn. Aside from not measuring numbers ported to another carrier, not all carriers age their numbers for the full time allowed. In particular, where carriers cannot immediately obtain new numbers from the NANPA or the pooling administrator because of area code rationing, and the carriers have no other available numbers to assign to end users, carriers may assign end users telephone numbers that have not been aged for the full time that the state regulatory commissions have prescribed. (Thousands-block pooling alleviates this problem by making more numbering resources available.) Moreover, as mentioned in the previous paragraph, wireline carriers do not always issue one telephone number per line. Thus, as with line counts, churn rates can only be roughly estimated from the data in Table 7. 18 See First NRO Order, 15 FCC Rcd at 7594, para. 41. Carriers obtain OCNs from the National Exchange Carrier Association. 19 Churn is the rate at which customers change carriers or disconnect service. U.S. Federal Communications Commission Numbering Resource Utilization in the United States 5 Table 8 focuses on telephone number pooling. It shows the number of thousands-blocks that carriers have received from the Pooling Administrator, the total number of thousands-blocks in telephone rate centers where pooling exists,20 and the percentage of those thousands-blocks that are pooled. A thousands-block is potentially poolable when 90% or more of the numbers are classified as available for assignment. Pooling is required in the top 100 Metropolitan Statistical Areas (MSAs).21 Pooling also occurs in other areas where a state regulatory commission has exercised delegated authority to require pooling.22 Carriers also have voluntarily implemented pooling in certain areas. The Commission established an initial national roll-out schedule for thousands-block number pooling for wireline carriers, which was completed in December 2003,23 and required most mobile wireless telephony carriers to participate in that schedule starting in August 2003.24 Table 9 examines the efficacy of thousands-block pooling by showing the utilization of the thousands-blocks that were distributed by the Pooling Administrator and the utilization rate that would have resulted had whole NXXs been issued. 25 Overall, if whole NXXs had been issued instead of individual thousands-blocks, utilization within those bl ocks would have been about 22%. With pooling, however, utilization was 64%, about a three-fold in crease. Another way of measuring the benefit of pooling is examining the quantity of telephone numbers saved through pooling. With pooling, 257 million telephone numbers were distributed to carriers in pooling areas. Had there been no pooling, over 740 million telephone numbers would have been distributed to the carriers. Thus, about 483 million telephone numbers have been saved through thousands-block pooling. Table 10 shows utilization data for two specia lized non-geographic area codes: 500 and 900. Area code 500 is used for “follow me” service, which, among other things, can be used to route an incoming call to different phone numbers, depending on the time of day. Area code 900 is used for information services where the caller is not charged the normal long distance rates set by the caller’s long distance carrier, but usually is charged much higher prices that are preset by the call’s recipient. 20 A rate center is a geographic area used to determine distances and prices for local and long distance calls. 21 The composition of MSAs may change over time. If a rate center is part of a top 100 MSA at any time after 1990, then the FCC generally requires number pooling. See Fourth NRO Order, 18 FCC Rcd at 12473, para. 2. 22 Most recently, the Commission granted authority to the Idaho, Alabama, and Wisconsin commissions to expand pooling to areas outside of the top 100 MSAs. See Numbering Resource Optimization; Implementation of the Local Competition Provisions of the Telecommunications Act of 1996, WC Docket 07-118, CC Docket Nos. 99-200, 96- 98, Order, 22 FCC Rcd 16081 (2007). The Commission also has sought comment on whether it should delegate authority to all states to implement mandatory pooling at their discretion. See Numbering Resource Optimization, CC Docket No. 99-200, Order and Fifth Notice of Proposed Rulemaking, 21 FCC Rcd 1833 (2006). 23 See The Common Carrier Bureau Announces The First Quarter Schedule For National Thousands-Block Number Pooling, CC Docket No. 99-200, Public Notice, 17 FCC Rcd 103 (2001). See also Numbering Resource Optimization, CC Docket No. 99-200, Order, 17 FCC Rcd 7347 (2002). 24 See Fourth NRO Order, 18 FCC Rcd at 12473, para 1; 68 F.R, 43009, July 21, 2003. Thus, the Commission required wireless telephone carriers to participate in thousands-block number pooling (starting on August 20, 2003) somewhat before they were required to begin deploying local number portability (by November 24, 2003). 25 Calculating the utilization rate had whole NXXs been issu ed was a 4-step process: 1) the number of thousands- blocks that a carrier held in a rate center was determined; 2) that number was rounded up to the next ten, which is the number of thousands-blocks the carrier would have received if it had received whole NXXs; 3) the number in step 2 was multiplied by 1,000 to calculate the total quantity of telephone numbers the carrier would have had in the rate center; and 4) the number of telephone numbers that the carrier actually has in that rate center is then subtracted from the quantity calculated in step 3. U.S. Federal Communications Commission Numbering Resource Utilization in the United States 6 Charts 1 through 4 focus on utilization rates as a function of the number of thousands-blocks that carriers of different types hold within a local geographic area.26 These charts show average utilization rates of incumbent LECs, mobile wireless carriers, CLECs, and paging carriers, respectively. We used rate centers as our measure of local geographic area because thousands-blocks are assigned to carriers on a rate-center basis. Carriers serving densely populated areas may need more than one thousands-block to provide service. In these densely populated areas, carriers should generally be able to achieve higher utilization rates than carriers serving less densely populated areas, where one thousands-block (or in many rural areas, a ten-thousands block) may be used to serve just a few customers. Table 11 focuses on NPA-NXX assignment information. There are three different databases that contain sources of NPA-NXX assignment information: the NANPA’s NRUF database, the NANPA’s NANP Administration System (NAS) database of NPA-NXX assignments, and the Local Exchange Routing Guide (LERG).27 For a variety of reasons, the databases are not identical. Timing is a large factor in the differences. For instance, during an area code split, a carrier will maintain both the old and new NPA-NXXs in its systems during the phase called permissive dialing. 28 After permissive dialing ends, the carrier should remove the old NPA-NXXs from its systems. During permissive dialing, some carriers report utilization data for both the old and th e new NPA-NXXs. Further, some carriers may not remove the old NPA-NXXs from their systems promptly after permissive dialing ends, and may therefore report utilization data on both the old and the new NPA-NXXs. Also, carriers sometimes delay updating the LERG after an NPA-NXX has been removed from their switch or when the carrier has given the NPA-NXX back to the NANPA. Thus, the NRUF da tabase, the NANPA assignment database, and the LERG may not be identical. Table 11 shows the number of NPA-NXXs that appear in the three databases. Table 12 shows the percentage of numbers that have been assigned to end users over time. The utilization rate for incumbent local exchange carriers is slowly declining and mobile wireless and CLEC utilization rates are generally increasing. The utiliza tion rate for paging continues to drop because the paging market is shrinking. Table 13 shows, on a quarterly basis, the number of NXX assignments made by the NANPA, the number of NXXs that have been returned to th e NANPA, and the number of net NXX assignments to carriers. The table shows that fewer NXXs generally are being issued each quarter, and that carriers continue to return unneeded NPA-NXX s to the NANPA for reassignment. 26 The points in Chart 1 were calculated using a three-step process. First, thousands-blocks were grouped depending on the number of thousands-blocks held by a carrier within a rate center. Second, the number of thousands-blocks held in a rate center was rounded to the nearest ten, to help protect the confidentiality of the data. Third, the average utilization rates were calculate d for each of the groups (i.e., from the group of 10 thousands-blocks per rate center through the group of 1,000 thousands-blocks per rate center). For example, for all instances where a carrier reported from 5 to 14 (which round to 10) thousands-blocks in a rate center, the average utilization rate was calculated. A similar average utilization rate was calculated for all instan ces where, for a carrier in a rate center, the number of thousands-blocks in a rate center was rounded to 20, 30, and so on through 1,000. To preserve carrier confidentiality, some data points have been collapsed into a single data point. For example, if there were only two companies with 350 thousands-blocks in a rate center, and another two companies with 360 thousands-blocks in a rate center, those data points were collapsed. This way, no carrier-specific data are released. 27 The NANPA’s assignment information can be found online: http://www.nanpa.com/reports/reports_cocodes_assign.html. The analysis in Table 11 examines only those codes that NANPA marked “assigned” (i.e., this study does not examine those code s marked “protected”, “reserved”, “unassignable”, or “vacant”). The LERG is published monthly by Telcordia Technologies. 28 During permissive dialing, a phone number may be called by using either the old or the new NPA. U.S. Federal Communications Commission Numbering Resource Utilization in the United States 7 Tables 14 through 16 display information on telephone number porting. All telephone number porting information in this report is derived from the local number portability database, which was designed solely for the purpose of routing calls.29 There are several reasons that the quantity of ported numbers in the database at any given time does not equal the sum of numbers ported in prior months. When consumers who have already ported their telephone numbers do so again, the porting database retains only the most recent porting activity for those numbers. Consumers can also port their numbers back to the original carrier.30 When this happens, it is counted as a port even though the number drops out of the porting database.31 Also, carriers sometimes port blocks of numbers to other carriers before reassigning them in the LERG. Once the numbers are reassigned, they can be dropped from the porting database. Table 14 shows, on a quarterly basis, the quantities of telephone numbers that have been ported since wireless porting started on November 24, 2003. The table shows that most porting activity is intramodal, that is between two landline carriers or between two mobile carriers. Many telephone numbers are ported so that they can be used with VoIP-based telephony. Because almost all VoIP providers get their numbers from CLECs, telephone numbers that are ported for VoIP-based service are included in the wireline-to-wireline totals. Table 15 shows the quantity of telephone numbers in the porting database at the end of each quarter. Table 16 is based on ports in the database as of September 30, 2010, and shows the quarter in which the numbers were ported. Table 17 shows the number of ports in the database on a state-by-state basis, and Table 18 shows the number of carriers involved in porting on a state-by-state basis. Table 19 shows the percentage of assigned numbers that were ported.32 Customers may port their numbers multiple times, and in doing so, they may change the nature of their service (wireline versus wireless), so there are two possible methods of determining whether a number was ported from a wireline carrier or not. The first method is to use the type of carrier that is currently porting the number away from itself, and the second is to determine which type of carrier originally held the number. The choice of methodologies depends on what is being measured. Because it is useful to know porting patterns for numbers as they are currently being used, Tables 14 and 19 use the porting carrier’s type to establish whether a wireline or wireless number is being ported. For the rest of the tables, the original carrier’s type is used to dete rmine the porting carrier’s type. This is done so that the number of wireless subscribers can be better determined.33 For instance, in order to properly calculate the number of wireless units at a particular point in time using telephone number data, one can take the quantity of wireless assigned numbers as reported on NRUF forms, add the number of wireline to wireless ports and subtract the number of wireless to wireline ports. 29 NeuStar, Inc. currently is the portability administrator and operates seven different porting databases. Commission staff combines information from these databases into a single database. 30 When a customer who is using a ported number discontinues service entirely, the ported number also goes back to the original carrier. 31 Area code splits can cause a number that was at one time ported from Carrier A to Carrier B to appear to be ported from Carrier A to Carrier B at a later date than actually occurred, as the database record must be updated to reflect the new area code. When this happens, the old porting record also disappears from the database. 32 Paging carriers are not required to port numbers. 33 According to NRUF rules, a number that is ported to another carrier is classified as assigned. In order to avoid double counting, the recipient of the ported number does not report ported numbers in NRUF. See 47 C.F.R. § 52.15 (f)(1)(v). U.S. Federal Communications Commission Numbering Resource Utilization in the United States 8 Tables 20 through 24 show information about toll-free numbers in the North American Numbering Plan. AT&T introduced toll-free service in 1967. The Commission changed procedures for routing toll-free calls on May 1, 1993 to make toll-free numbers "portable." This change enabled customers to switch service providers yet retain their toll-free numbers. The quantity of assigned toll-free numbers grew rapidly, and new toll-free calling codes were opened to meet the demand. In March 1996, calling code 888 was placed into service. The third toll-free calling code (877) went into effect April 4, 1998, and the fourth toll-free calling code (866) went into effect July 29, 2000. The Wireline Competition Bureau authorized Database Service Ma nagement Inc. (DSMI), which maintains the Toll- Free Service Management System for the United States and Canada, to open the 855 toll-free area code on October 1, 2010.34 In the event that another toll-free code is needed, the 844 code would be opened. As of September 30, 2010, there were over 28 million toll-free numbers assigned. Tables 21 through 24 show the growth of each individual toll-free code over the past decade: 800, 888, 877, and 866, respectively. Table 25 shows the current list of area codes, the state or territory they serve, and the month the code was opened. Table 26 shows area code assignments since January 1999, along with the month the code was added, and the code that served the area previously. Table 27 shows how dialing patterns differ from state to state. For instance, in some states, callers making local calls within an area code are required to dial only the 7-digit phone number. In other states, callers making local calls must dial the ten-digit phone number (area code plus the phone number). Finally, in some states, local callers must dial a “1 ” before dialing the area code plus the phone number. Each state’s public utilities commission (or public service commission) determines the calling pattern for each area code in their state.35 For both local and domestic toll calls, there are two basic types of calls: those within an area code and those between area codes. Table 27 shows the dialing patterns for all four types of calls. The last column of Table 27 indicates whether all toll calls in that state require callers to dial a “1” before the telephone number. Additional Information Additional information too lengthy to include in this report is contained on the Commission’s website.36 The first set of additional information lists the more than 2,700 filers. The list includes the service provider’s name, its parent name, and its OCN. The second set of information shows, by carrier type and by rate center, the number of assigned telephone numbers and the number of thousands-blocks reported in that rate center. Some information has been redacted (asterisked out), to prevent the potential release of non-public data. The information 34 See http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-10-1117A1.pdf. 35 The dialing patterns for area codes are listed in the area code database, which can be found at http://www.nanpa.com/area_codes/index.html. 36 This report and additional numbering information can be found at http://www.fcc.gov/wcb/iatd/number.html. All of the Industry Analysis & Technology Division’s re ports are available on the web, and are conveniently categorized. See http://www.fcc.gov/wcb/stats. U.S. Federal Communications Commission Numbering Resource Utilization in the United States 9 also includes the Metropolitan Statistical Area/Primary Metropolitan Statistical Area in which the rate center resides.37 The pooling information submitted by NeuStar, Inc. is also available, and includes the NPA, NXX, X (block number), recipient carrier, date of ass ignment for the block, and other information about the block. NeuStar, Inc. submitted pooling data as of October 15, 2010. For consistency with the latest available NRUF data, only blocks whose assignment was effective by June 30, 2010 were used in creating the tables for this report. Technical Details The following material provides technical details on the data and procedures used in this analysis. With respect to Tables 1 through 3, the reader should note that the number of unique NXXs for each carrier type does not add up to the total number of unique NXXs. 38 This discrepancy occurs when multiple carriers report data for the same numbering resource. In addition, some carriers reported at the thousands-block level and other carriers reported at the NXX level for the same NXX. Further, when all mobile wireless devices were assigned telephone numbers and subscribers generally carried one mobile device for making voice calls, NRUF provided reasonably accurate measures of mobile wireless telephone subscribership. However, consumers are now more likely to use more than one mobile device – particularly non-voice devices, such as Internet access devices (e.g., wireless modem cards, netbooks, and mobile Wi-Fi hotspots), e-readers, tablets, and telematics systems – that commonly are assigned telephone numbers. In addition, certain mobile broadband providers do not assign telephone numbers to some or all of the devices on their networks. This trend became noticeable around 2005, and since that time, the wireless NRUF data has reflected the number of individual subscribers plus a share of the mobile wireless connections or connected devices.39 In the past, when numbers were transferred from an incumbent LEC to another carrier, these numbers were classified as “assigned” because tho se numbers could not be used elsewhere in the incumbent LEC’s own system. According to the Co mmission’s standardized definitions, however, these numbers are classified as “intermediate” numbers. It appears that some large carriers have not reported these numbers as intermediate numbers. Because, in many instances, we were unable to match submissions that report intermediate numbers with submissions that report numbers as being received from another carrier, we had to create filters to ensure that numbers were not double counted. Where a Regional Bell Operating Company (RBOC) has acquired a carrier with CLEC services in the RBOC's operating region, the numbering resources of the acquired CLEC that are in the RBOC's operating region are counted as incumbent LEC resources. Where the acquired CLEC provides services outside of the acquirer's operating region, the numbering resources are treated as CLEC resources. For ease of comparison, Charts 1 through 4 plot utilization rates only when there were 1,000 or fewer thousands-blocks in a rate center. Some incumbent LECs reported more than 1,000 unique thousands-blocks in a single rate center. The average utilization rates in these instances (where the carrier has more than 1,000 thousands blocks in a rate center) were the same as the instances where the carrier has just fewer than 1,000 thousands blocks in a rate center. Therefore, the charts show only the data 37 The rate center’s V&H coordinates from the LERG were used to determine in which MSA/PMSA the rate center resided. If the rate center is not in an MSA/PMSA, then the MSA/PMSA variable is left blank. 38 In some instances, more than one carrier reported numbering utilization data for the same NPA-NXX. Tables 1-3 report on the number of unique NPA-NXXs that were reported by each carrier type and by the industry as a whole. 39 See Fifteenth CMRS Report pages 8 – 9. http://hraun foss.fcc.gov/edocs_public/attachmatch/FCC-11-103A1.doc. U.S. Federal Communications Commission Numbering Resource Utilization in the United States 10 where the carriers reported up to 1,000 thousands-blocks within a rate center. This allows a linear scale to be used. In some instances, we observed that some CLECs had a large number of thousands-blocks in a single rate center. Although most CLECs do not have enough end-user lines in a rate center to warrant having so many thousands-blocks in that rate center, there are at least two reasons that a CLEC would do so. First, some CLECs provide service to unified messaging services, such as e-fax.40 These services use large quantities of numbers.41 Also, VoIP providers generally obtain NANP telephone numbers for their customers by partnering with a local exchange carrier, such as a CLEC, through a commercial arrangement rather than obtaining them directly from a numbering administrator. * * * * We invite users of this information to provide suggestions for improved data collection and analysis by using the attached customer response form, e-mailing comments to craig.stroup@fcc.gov , john.vu@fcc.gov , or calling the Industry Analysis and Technology Division at (202) 418-0940 (for TTY, call (202) 418-0484). 40 Unified messaging services allow end users to receive multiple types of messages (such as voice mail and faxes) at one phone number. Typically, these messages are then digitized and e-mailed to the end user. Because the end user does not need to answer the call personally, the messages can be sent to any phone number in the United States. Thus, unified messaging service providers can operate efficiently by obtaining a large number of thousands blocks in a single rate center. 41 Carriers assigning numbers to unified messaging services are instructed to report numbers as “intermediate” until the numbers are assigned by the unified messaging service providers to end users. Some carriers have assigned large quantities of numbers to unified messaging services but may not have received information back from the unified messaging company as to whether those numbers had been assigned to end users. This may explain why some carriers reported dozens of NXXs in a single rate center, yet classified all those numbers as intermediate rather than assigned.

Carriers typically obtain at least one OCN per state in which they do business. Thus, carriers with multiple OCNs are counted multiple times with the exception that is noted following Table 3. 2 Carriers occasionally misclassify the type of service that they provide. For instance, the CLEC operations of incumbent LECs are occasionally classified as incumbent LEC operations.

The database contains the date when the telephone number record was last updated. For most telephone numbers, this was the most recent port. For those telephone numbers affected by area code changes, however, the date refers to when the record was updated to reflect the new area code. See the text for a fuller discussion. 4 Starting with the July 2007 data, the method of determining whether a port came from a wireline or wireless carrier changed. For numbers that have been ported multiple times, the original carrier is now used to determine the porting carrier's type. Previously, the porting carrier's type was based on the most recent port. This was done to better estimate the number of phone numbers used in wireline and wireless service. 3 Data from prior periods can be found in the "Data as of June 30, 2009" edition of this report, which can be found at: http://www.fcc.gov/wcb/iatd/number.html.

Source: Raw data from Local Number Portability Administrator (NeuStar, Inc.). Rollups performed by the Industry Analysis and Technology Division staff, Wireline Competition Bureau. 2 The local number portability database was designed solely for the purpose of routing calls. As such, it retains only the most recent porting activity for any given number. So if a consumer ports a number from Carrier A to Carrier B, and later the consumer then ports the number from Carrier B to Carrier C, the database will not reflect the original port from Carrier A to Carrier B. Also, numbers that revert back to the original carrier (either because the customer ports the number back to the original carrier or because the customer discontinues service with that number) are dropped from the database. Lastly, area code splits can make a number appear to be ported later than it actually was. Starting with the July 2007 edition of this report, the methodology for determining whether a number was ported away from a wireline or a wireless carrier changed. Rather than relying on the carrier type of the most recent port, the numbers now reflect the original carrier type, based on the carrier that is assigned the thousands block of the donated number. 3 Data from prior periods can be found in the "Data as of June 30, 2009" edition of this report, which can be found at: http://www.fcc.gov/wcb/iatd/number.html.

On May 1, 1993, procedures for routing toll- free calls were changed and 800 numbers were made "portable" so customers who switched service providers could retain their numbers. Due to the growth in demand for toll-free numbers, a new toll-free calling code, 888, was added in March 1996, which made it possible to assign about 8 million new toll-free numbers. A third toll-free calling code, 877, was added in April 1998; and a fourth toll-free code, 866, was added in July 2000. 3 On February 15, 2008, SMS800 freed up all unused numbers contained in certain blocks of numbers that were reserved for the provision of certain mobile radio telecommunications (pager) services within a specified geographic area. These numbers were in NPA 800 and had NXXs in the range of NX2 where ‘N’ = 2 through 9 and ‘X’ = 0 or 1 and the numbers ended in a state code.
