Federal Firearms License (FFL)
The federal license required to deal in firearms — a prerequisite for a compliant firearms merchant account.
A Federal Firearms License (FFL) is the license required to manufacture or deal in firearms in the United States. For payments, a valid FFL is the baseline an acquiring bank verifies before approving a firearms merchant.
Beyond the license, firearms sellers must show age-verification and shipping controls. With those in place, a supportive acquirer can bank the category that most generalist processors refuse.
