Yes. A person who timely files an application for renewal of a license may continue operations authorized by the expired license until the application is finally acted upon. An application is timely filed when it is received accurate and completed at the P.O. Box listed on the application form with the appropriate renewal fee.
If a person does not timely file a license renewal application and the license expires, the person must file ATF Form 7 (5310.12), Application for License, or an ATF Form 7CR (5310.16), Application for License (Collector of Curios or Relics), as required by 27 CFR 478.44, submit the application fee applicable to a new business, and obtain the required license before continuing business activity.
