The current Commission Registration System (CORES) system will be retired during the Spring of 2019; after the system is retired, customers wishing to create a new FCC Registration Number (FRN) or modify an existing FRN will need to create an FCC Username Account in the updated CORES system. This Username Account will allow customers to create new FRNs, modify existing FRNs, and associate existing FRNs to their Username Account.

At this time, there are no changes to how other FCC systems associate resources (applications, licenses, etc.) to FRNs.
