CORES/FRN Information


If you wish to conduct business with the FCC, you must first register through the FCC’s COmmission Registration System (CORES).  Upon registration, you will be assigned a FCC Registration Number (FRN).  This number will be used to uniquely identify you in all transactions with the FCC.  Other than the initial registration process to receive your FRN you will not have to disclose your SSAN again.  If you do not have an Amateur Radio license already, we highly recommend you apply for your FRN before you take your initial license examination.


To register in CORES and receive your FRN, go to this web site:




Click on the “Register” option, and fill out the FRN registration form.  After you submit the registration form you will receive an email from the FCC with your FRN number and a temporary password.  You can change this temporary password to a password of your liking.


Keep your FRN and password in a safe location because you will have to have it in order to access your account with the FCC in the future to complete a change of address, renew your license and any other dealings with the FCC.


You can also call the FRN Help Line at 877.480.3201 (Monday-Friday 8:00 AM-6:00 PM EST) for assistance in registering in CORES and/or getting your FRN.
