USE OF THE FCC REGISTRATION NUMBER (FRN) IS MANDATORY
The use of FRNs became mandatory effective December 3, 2001, meaning that all transactions 
with the FCC now require use of an FRN number.  If there is no FRN present on the remittance 
advice form (Form 159, Form 159-B or Form 159-W) submitted by the regulatee to make fee 
payment, the FCC will send the filer a notice stating that the payment was received without a 
FRN and that proper credit for the payment will not occur until the FRN is provided.  Regulatory 
fee payments received without a FRN will be retained by the FCC.  Also, a separate remittance 
advice form is required for each licensee FRN. 
You may check the Commission Registration System (CORES) to register for a FRN, to 
determine if you are still registered, or if you have forgotten your FRN.  If you do not yet have a 
FRN, you can register for one through the FCC website listed below, or by completing a Form 
160 (CORES Registration Form) and submitting the Form 160 along with your payment.  
To obtain a FRN:
· Register at www.fcc.gov, click on the CORES Registration link in the left 
margin.
· Complete Form 160.  You may obtain Form 160 at 
http://www.fcc.gov/formpage.html or by calling the FCC’s CORES Helpdesk 
at 1-877-480-3201.  You may also pick up Form 160 in Commission Room 
TW-B200. 
To search for an FRN:
· To check your pre-assigned FRN at www.fcc.gov, click on CORES 
Registration link in the left margin.
If you are unable to register electronically, then submit your completed Form 160 directly to Mellon 
Bank along with your payment and completed remittance advice form (Form 159, Form 159-B or 
Form 159-W).  Mellon Bank will register you and you will receive a confirmation letter from the 
FCC through the U.S. Postal Service mail.  Your regulatory fees will be credited to that FRN.
