Pawn shops/pawnbroker businesses are regulated by the Arizona Revised Statutes. Pawnbrokers need to be licensed by the sheriff of the county in which the person regularly conducts business in addition to any other requirements. You may also wish to consult your attorney for assistance.
If you are selling firearms and ammunition, contact the Federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) for their requirements, in addition to your local fire department. (15)
