LEGACY CORES USERS MUST REGISTER IN THE NEW CORES SYSTEM
Legacy CORES (COmission REgistration System) users must register in the new CORES System.  The FCC retired the legacy version of CORES on July 15, 2022.  The updated version of CORES Registration has been available since 2016, but most amateurs do not know it is available.

The FCC is advising all users to transition to the updated CORES system as soon as possible to take advantage of the new features and security enhancements.  Additionally, licensees must be registered in the new system to be able to pay the $35 FCC application fee required for license renewals, vanity call sign requests, and new licenses.

CORES INSTRUCTIONS
Licensees who haven’t already created a CORES account must register a unique username (your email address) and a password. Visit the FCC CORES website to set up your account. If you don’t know your FRN, you may search for it on that web page. You will need your FRN for the next step.

Log into your new account and click the first option, ASSOCIATE USERNAME TO FRN.
Enter your FRN and comment. An example of a comment is ”Associating FRN.”
Click CONTINUE.

If you know your password to your FRN, enter it now. This password will likely be different from the one used for your username account. If you do not know your FRN password, choose the “Forgot FRN Password” option. You can also call the FCC at 877-480-3201 to have them reset your password for you.

Once you have completed these steps and your FRN has been associated with your username, the site should bring you back to the main menu. Log out.

You can view these instructions on the FCC Registration Help page.  Your FRN can also be found in the system by searching for your call sign on the FCC’s License Search page.

The FCC also offers helpful CORES Tutorial Videos. Specifically, view the videos “Getting Started With the New CORES” which explains how to register for a CORES Username account and “Associating an FRN to a Username” which instructs legacy CORES users on how to link an existing FRN to a username.  The FCC also has a license renewal instructions page.  Visit the ARRL website for further information about the FCC application fee.

For assistance, call the FCC Licensing Support Center at 877-480-3201 (Mon.-Fri. 8 a.m.-6 p.m. ET), or submit a help request on the FCC’s Wireless Licensing Help Center website.
