Alcohol, Tobacco, Firearms, and Explosives Bureau

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is responsible for enforcing Federal criminal laws and regulating the firearms and explosives industries.

ATF, formerly known as the Bureau of Alcohol, Tobacco, and Firearms, was initially established by Department of Treasury Order No. 221, effective July 1, 1972, which transferred the functions, powers, and duties arising under laws relating to alcohol, tobacco, firearms, and explosives from the Internal Revenue Service to ATF. The Homeland Security Act of 2002 (6 U.S.C. 531) transferred certain functions and authorities of ATF to the Department of Justice and established it under its current name. ATF works, directly and through partnerships, to investigate and reduce violent crime involving firearms and explosives, acts of arson, and illegal trafficking of alcohol and tobacco products.

The Bureau provides training and support to its Federal, State, local, and international law enforcement partners and works primarily in 23 field divisions across the 50 States, Puerto Rico, the U.S. Virgin Islands, and Guam. It also has foreign offices in Mexico, Canada, Colombia, and France.
