To get an FRN number, go to the FCC’s Commission Registration System (CORES) at apps.fcc.gov/cores, create a username, and register. The process is free, takes about ten minutes, and your 10-digit FCC Registration Number appears on the confirmation screen right away. The number never expires and stays with you for every future dealing with the FCC.1eCFR. 47 CFR Part 1 Subpart W – FCC Registration Number
An FRN is the account number the FCC uses to link your licenses, applications, and payments to a single identity. You need one before you can file an application, pay a fee, bid in a spectrum auction, contribute to the Universal Service Fund, or pay a forfeiture.1eCFR. 47 CFR Part 1 Subpart W – FCC Registration Number
What to Have Ready Before You Start
Gather three things before opening the registration page:
- A valid email address. This becomes your CORES username, and the FCC will send a verification link to it during signup.
- Your full legal name and mailing address.
- A taxpayer identification number. Individuals use their Social Security Number; businesses use their Employer Identification Number. The FCC collects this under the Debt Collection Improvement Act of 1996.2Federal Communications Commission. Debt Collection Improvement Act Implementation
Your SSN or EIN is stored internally and never displayed publicly. The FRN itself is what appears in FCC filings and databases, so your taxpayer number stays private.
Businesses should note two rules. Each subsidiary with its own taxpayer ID needs a separate FRN, and a single company can hold multiple FRNs if that fits its operations.3eCFR. 47 CFR 1.8002 – Obtaining an FRN
Register Through CORES
Create Your Username
Open apps.fcc.gov/cores and click Register. Enter your email, set a password, and answer the security questions. Passwords must be 12 to 15 characters with at least one lowercase letter, one uppercase letter, one number, and one special character.4FCC Registration System. FCC Registration System – Passwords Confirm your email address using the verification link the FCC sends, and your username goes live.
Register the FRN
Log in and choose the option to register a new FRN. You’ll indicate whether you’re registering as an individual or an entity, confirm whether your address is inside the United States, and enter your name, address, and taxpayer ID.1eCFR. 47 CFR Part 1 Subpart W – FCC Registration Number Review everything before you submit. Your 10-digit FRN appears on the confirmation screen immediately.
Paper Alternative
If you’d rather not register online, complete FCC Form 160 and mail it to the FCC at 44 L St NE, Room 3-136, Washington, DC 20554. The form is available as a PDF on the FCC website. This route takes longer because the FRN isn’t issued in real time.
h2>If You Don’t Have an SSN or EIN
The system has built-in options for people who can’t provide a U.S. taxpayer ID. Foreign individuals, foreign businesses, foreign government agencies, amateur radio clubs, tribal governments, and petitioners can register by selecting the applicable exemption reason during registration.5FCC Commission Registration System. Taxpayer Identification Number (TIN)
If you’ve applied for an EIN but haven’t received it yet, you can select that option and update your record once the IRS assigns your number. Online registration otherwise works the same way for domestic and foreign applicants, with only minor differences in the address fields.6FCC Commission Registration System. Registration
Cost
There is no fee for the FRN itself. Costs come later, when you file for an actual license or authorization. A new amateur radio license application currently costs $35,7Federal Communications Commission. Personal Service and Amateur Application Fees and commercial license fees vary by service. Simply holding an FRN without any active license does not trigger any charges.
After You Have Your FRN
Your FRN is tied to the CORES username that created it, and that username is automatically the FRN Administrator. If you already had an FRN from before the current CORES system launched, you can associate that older FRN with your new username so it works across other FCC systems.8FCC Commission Registration System. What You Need to Know
Federal rules give you 10 business days to update your FRN record after any change to your name, address, email, or other registration details. Log into CORES to edit the fields, or file FCC Form 161.1eCFR. 47 CFR Part 1 Subpart W – FCC Registration Number Outdated contact information can mean missed FCC correspondence, including payment deadlines and license renewal notices.

Three wrong answers locks the account, and the only way back in is to call FCC support at 877-480-3201, Monday through Friday, 8 a.m. to 6 p.m. ET.

Watch Out for Debts Owed to the FCC
The FCC’s Red Light Display system flags delinquent debts against your FRN, whether from unpaid regulatory fees, overdue auction payments, application fee shortfalls, or unpaid forfeitures.10Federal Communications Commission. Red Light Frequently Asked Questions The agency will dismiss any pending application filed under an FRN with a delinquent debt.
Registering a second FRN doesn’t solve this. Because FRNs are linked by taxpayer ID, a debt attached to one FRN can block applications filed under a different FRN sharing the same SSN or EIN.2Federal Communications Commission. Debt Collection Improvement Act Implementation Unpaid regulatory fees also carry a 25% late penalty,10Federal Communications Commission. Red Light Frequently Asked Questions and the Debt Collection Improvement Act requires the FCC to refer delinquent debts to the Treasury and to credit bureaus. Paying in full or setting up satisfactory payment arrangements is the only way to clear the flag.
