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.

For laws:

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.
