See our Dealer Regulations policy summary for a comprehensive discussion of this issue.
Federal law requires firearms dealers to obtain a license from the Bureau of Alcohol, Tobacco, Firearms & Explosives (ATF), although resource limitations prevent the ATF from properly overseeing all its licensees.
- Requiring firearm dealers to conduct a background check on purchasers, see the Colorado Background Checks section;
- Setting the procedure for firearm dealers to conduct background checks on behalf of unlicensed firearm sellers, please see the Colorado Universal Background Checks section;
- Requiring firearm dealers to keep records of, or report firearm sales, see the Colorado Retention of Sales & Background Checks Records section; and
- Requiring firearm dealers to ensure that purchasers possess a locking device, see the Colorado Locking Devices section.
Colorado also requires gun dealers to post a sign that states Colorado’s prohibition on knowingly purchasing or obtaining a firearm on behalf of, or for transfer to, another person the purchaser knows or reasonably should know is ineligible to possess a firearm.1 The dealer must post the sign in an easily readable manner, in an area that is visible to the public at each location from which the dealer sells firearms.2
Colorado does not require firearms dealers to obtain a state license or undergo regular inspections.
