If you wish to conduct business with the FCC, you must first register through the FCC's Commission Registration System (CORES). After registering you will be assigned a FCC Registration Number (FRN),
which will 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 Social Security Account Number (SSAN) again. If you do not have a FRN, I 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 for step-by-step instructions for registering a new Username Account in the CORES system. Be sure to record your password, the Personal Security Question and the answer:
Bring your FRN number with you to the test session. When you fill out the NCVEC Form 605, put your FRN number in the block where it asks for it.
If you have any questions about the application process, you can contact the FCC at 877.480.3210 from 0800-1800 EST.
