The term FFL is used to describe a Federal Firearms License. We are often asked whether a person needs an FFL to sell a gun. The answer is, “typically, yes.” Generally, an FFL is necessary for people to sell firearms. However, there are exceptions. Under federal law, specifically 18 USC 922, it is unlawful for any person “except a licensed importer, licensed manufacturer, or licensed dealer” to “engage in the business of dealing” in firearms.
