|Some radioamateurs were previously issued an FRN. If you do not currently have an FRN and would like to obtain one, you should register your TIN and call sign prior to November 28, 2001. After this date, you should access CORES registration from the ULS TIN/Call Sign registration screen. This method will ensure that you have the ability to associate call signs with your newly issued FRN.
Effective November 28, 2001, follow these steps: Select "TIN/Call Sign Registration" from the ULS homepage. Choose the "Register Now" button, and click "Continue" to be automatically linked to CORES. Provide the required information and you will receive a confirmation screen displaying your FRN number. Record this number for future reference. Choose the ULS link on the confirmation screen to return to ULS.
