US Cop

US Cop is an independent, offline directory of a deliberately limited set of current nationwide federal law-enforcement contacts.

This edition includes source-attributed contacts for the FBI, DEA, ATF, U.S. Marshals Service, and U.S. Postal Inspection Service. Each record shows its official source and verification date. Search works offline, and important values can be copied. Phone, Maps, Mail, and Safari open only after you choose and confirm an available action.

The directory is intentionally conservative. It is not a complete directory of federal, state, local, tribal, or territorial agencies. Contact details can change after verification; confirm important information directly with the agency.

US Cop is independent and unofficial. It is not affiliated with or endorsed by any government or law-enforcement agency. It is not for emergencies. In the United States, call 911.
