What You Need to Know

  1. Why do I need a username and password?

If you wish to conduct business with the FCC, you must first register an FCC Registration Number through the FCC's COmmission REgistration System (CORES). To access CORES, you must create a unique username and password in the FCC User Registration System.

You will use this username to access CORES to update your FRN information and reset/update your FRN Password (Only FRNs created in the Legacy CORES have a password of their own). CORES will now require FRNs to have Administrator(s). These user(s) will manage which users have access to the FRN and what user role they will have.

  1. What is an FRN?

An FRN, or FCC registration number, is a 10-digit number that is assigned to a business or individual registering with the FCC. This unique FRN is used to identify the registrant’s business dealings with the FCC. FRNs created in the Legacy CORES have a password.

Presently, some FCC licensing systems allow you access using the FRN and the FRN password. In the updated CORES, you will associate previously registered FRNs to your username, and the FRN may be used in other FCC systems that still allow FRN login along with your Username password. FRNs registered in the updated CORES DO NOT have a password of their own, the associated Username’s password can be used with the FRN where still applicable.

  1. Why must I register with the FCC?

Effective Dec. 3, 2001, all applications and remittance must use an FRN.

Registering via the FCC Registration site is how you provide the FCC with basic information. Each individual or organization doing business with the FCC is required to provide and maintain current official contact information. The contact information you provide will be used to communicate important FCC-related information to you.

  1. What do you mean by "doing business" with the FCC?

A filer, licensee, certificate holder, or any entity sending payments to the FCC is considered to be doing business with the FCC and must, therefore, have an FRN. To register for an FRN, you must access CORES with your registered username and password.

  1. Why should I register for an FRN on the Internet and not by paper form?

The CORES online portal provides you with the easiest and fastest way to receive your FCC Registration Number (FRN). It also provides you with tools to manage your FRN, including viewing financial related information. Upon registering online, your FRN will be available to you immediately.

  1. If I register for a username to access CORES, will that affect my ability to access other FCC systems?

In addition to CORES, various other FCC systems have started allowing users to log in with their FCC Username. Some systems still require FRN and FRN-password to login. As an added feature, you will be able to log in to FCC systems that still require an FRN using your FRN and FRN-Password OR your FRN and Username-Password.
