FRN

Federal Registration Number (FRN)

To get an FCC issued FRN number, which is needed to take any FCC exam, you must register with the FCC.

For instructions on how to register with the FCC and receive an FRN, visit the FCC’s Registration page and the FCC’s Registration instructions page. Go to https://www.fcc.gov/rofrn for a video on creating an FCC account and getting your FRN.

New Customers of the FCC

1. In order to register for an FRN, customers are required to setup an FCC Username, please see instructions:  Registering/Creating a Username Account in CORES.
2. Once a username is set-up, customers need to log into CORES, to Register for a New FRN.  This new FRN is automatically linked to your Username Account and you are the Administrator of the FRN.  Use this FRN with your Username-password to log into ULS or any other FCC systems requiring an FRN and password login credentials.

Existing Customers of the FCC

1. Customers that already have an FCC FRN still need to register a Username account to access CORES.  Access to CORES is required to pay application fees.  CORES allows customers to: Manage their FRNs; View Financial standing with the FCC; Retrieve and pay fees, such as ULS application fees; and annual regulatory fees. Please see instructions: Registering/Creating a Username Account in CORES
2. Once a username account is set-up and customers successfully log into CORES, the next step for those that already have an FRN is to Associate an Existing FRN to a Username Account.
3. Upon successfully associating an existing FRN to the Username Account, customers may login to ULS using your FRN and Username Password to proceed to file an application, or login to CORES to continue with the Payment Process for an application filed in ULS.
