The FCC is planning on retiring the Legacy Commission Registration System (CORES). Customers wishing to register a new FCC Registration Number (FRN) or modify an existing FRN are encouraged to use the updated Commission Registration System. Users of the updated CORES will need an FCC Username to login. Please go to the FCC User Registration System to register an FCC Username.
