The FCC mails you a renewal notice 90 days before your license expires, and you have a window of six months to renew

Your ham radio license renewal happens through the Federal Communications Commission (FCC), not your state. The FCC will send you a paper notice by mail roughly three months before your license expires — check the expiration date printed on your current license to know when to expect it. You can renew starting six months before expiration and up to six months after, so you have a full year window, but waiting until after expiration means your station goes silent until the FCC processes your renewal.

The renewal process itself is straightforward: you fill out FCC Form 605, pay the filing fee (currently $170 for most amateur radio licenses, though this can change), and submit it either online through the FCC's Universal Licensing System or by mail. Most people renew online because it takes minutes and you get confirmation when ready. If you renew before expiration, your new license term begins the day your old one ends. If you renew after expiration, there is a gap where you cannot legally transmit.

Key Takeaways

  • The FCC sends renewal notices by mail about 90 days before expiration, but you can renew online anytime in the six months before or after your license expires.
  • You need your FCC Registration Number (FRN) and call sign to renew, both printed on your current license or available through the FCC's ULS database.
  • The filing fee is $170 for most amateur radio licenses, paid when you submit Form 605 through the FCC's online system or by check if you mail it.
  • Renewing online through the Universal Licensing System takes about 10 minutes and you receive confirmation the same day, while mail renewal takes 4 to 6 weeks.
  • If your license expires before you renew, you cannot legally operate your station, but you can still renew up to six months late without reapplying from scratch.

Getting your FCC Registration Number and gathering required information

Before you start the renewal, you need two pieces of information from your current license: your FCC Registration Number (FRN) and your call sign. Both are printed on the license card the FCC sent you when you first passed your exam. The FRN is a 10-digit number unique to you; the call sign is the letters and numbers you use on air (for example, W5ABC or N0XYZ).

If you have lost your license card or cannot find it, you can look up both numbers on the FCC's Universal Licensing System (ULS) at wireless.fcc.gov/uls. Click "Search" and enter your call sign in the search box. The ULS will show your current license record, including your FRN, expiration date, and license class (Technician, General, or Extra). Write down the FRN before you start your renewal process — you will need it to log in.

You will also need a valid mailing address and, if anything has changed since your last renewal (your name, address, or email), you should have that information ready. The FCC uses your address to mail your renewed license, so make sure it is current.

Renewing online through the FCC's Universal Licensing System

Online renewal is the fastest route. Go to wireless.fcc.gov/uls and click "Login" in the upper right. Enter your FRN and password (if you have renewed online before, you already have a password; if not, you will create one on your first visit). Once logged in, look for "Renew License" or a similar option in the menu — the exact wording changes occasionally, but it is always on the main dashboard.

The system will pull up your current license information and ask you to confirm or update it. Review your name, address, and call sign. If anything is wrong, correct it now — this is your chance to update your mailing address if you have moved. The form will also ask whether you want to renew at your current license class or upgrade (for example, from Technician to General). Most people straightforward renew at the same level.

At the end of the form, you will see the filing fee ($170 for most licenses). Pay by credit card or debit card — the system accepts Visa, Mastercard, American Express, and Discover. After you submit payment, the FCC issues you a receipt number when ready. Your license is officially renewed at that moment, even though the FCC will not mail your new card for several weeks. You can print the receipt as proof of renewal if you need it.

Mailing a paper renewal if you prefer not to go online

If you do not have internet access or prefer to mail your renewal, read FCC Form 605 from the FCC website (fcc.gov/wireless/licensing-databases/universal-licensing-system) or call the FCC at 1-888-CALL-FCC to request it by mail. Fill out the form by hand or type it. You will need to enter your FRN, call sign, name, address, and license class. The instructions on the form walk you through each field.

Include a check or money order for $170 made out to "FCC" and mail everything to the address listed on the form (currently the FCC's office in Gettysburg, Pennsylvania, but always verify the current address on the form itself). Mail renewal takes 4 to 6 weeks from the time the FCC receives it, so send it at least two months before your license expires if you want your new card before the old one runs out.

Keep a copy of the form and your cancelled check or money order receipt. If the FCC does not process your renewal within six weeks, you can contact them with your receipt number to check the status.

What happens if your license expires before you renew

If your license expires and you have not yet renewed, you cannot legally transmit on any frequency until the FCC processes your renewal process. This includes emergency communications — the FCC does not grant a grace period for operating after expiration. However, you can still renew up to six months after expiration without reapplying for your license from scratch (which would require passing the exam again).

The moment you submit your renewal process — whether online or by mail — you are back in the system, and the FCC will process it. If you renewed online, you are officially renewed when ready upon payment. If you mailed a paper form, you are renewed once the FCC receives and processes it, which takes several weeks. During that processing time, your license is still technically expired, so do not transmit.

To avoid this situation, renew at least 30 days before expiration. The online system is available six months in advance, so there is no reason to wait until the last minute.

Updating your information during renewal

Renewal is the right time to update your mailing address, email, or phone number. The FCC uses your mailing address to send your new license card, so if you have moved, change it before you submit your renewal. You can also update your email address so the FCC can contact you about future renewals or any licensing issues.

If you want to change your license class during renewal (upgrade from Technician to General, for example), you can do that through the renewal form, but you must have already passed the exam for the higher class. The FCC will not let you upgrade without proof that you have passed the test. If you have passed a higher-class exam but have not yet received your upgraded license, contact the FCC before renewing to make sure your exam results are in the system.

You cannot change your call sign through the renewal process. If you want a different call sign, that is a separate request made through the ULS after your renewal is complete.

Timeline and what to expect after you renew

If you renew online, your license is active the moment you pay. The FCC will mail your new license card within 2 to 4 weeks. Until it arrives, you can operate using your old card or print your receipt from the renewal as proof that you have renewed.

If you mail a paper form, the FCC processes it within 4 to 6 weeks of receiving it. Your license becomes active once they process the form, not when you mail it. The new card arrives a week or two after processing.

Your new license term runs for 10 years from the date your old license expired (or from the date the FCC processes your renewal if you renewed after expiration). The FCC will mail you another renewal notice about 90 days before the new expiration date.

Frequently Asked Questions

Can I renew my ham radio license if I have not been using it?

Yes. The FCC does not require you to prove you have been active on the air. You can renew even if you have not transmitted in years. However, if you let your license expire and do not renew within six months, you will have to pass the exam again to get a new license.

What if I lost my license card but still have my call sign?

You can look up your FRN on the FCC's ULS website using your call sign, then use that FRN to renew online. You do not need the physical card to renew. Once you renew, the FCC will mail you a new card.

Do I have to renew at the same license class?

No. If you have passed a higher-class exam (for example, you passed the General exam after getting your Technician license), you can upgrade during renewal. Select the higher class on the renewal form. You cannot downgrade to a lower class during renewal.

What if the FCC website is down when I try to renew?

The ULS is usually available, but if it is down, you can mail a paper Form 605 instead. The FCC publishes the mailing address on the form itself. Mail renewal takes longer, so plan ahead if you know the website is having issues.

Can someone else renew my license for me?

No. Only you can renew your license using your FRN and password. If you need help filling out the form, someone can information you, but you must submit it yourself or sign a paper form if you mail it.
