An updated version of the Commission Registration System (CORES) became available to the public on September 1, 2016. This new functionality allows users to register for a new FCC Username Account.This Username Account allows customers to create new FRNs, modify existing FRNs, associate existing FRNs to their Username Account, and view the financial history of associated FRNs. These changes are designed to enhance security and make CORES more user-friendly. Additional details about these modifications can be found on the updated CORES website at the FCC Registration Help Page, which provides guidance for how to:

The current Commission Registration System (CORES)  will be retired during the Fall of 2016; 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.

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