United States Postal Inspection Service

The United States Postal Inspection Service, founded by Benjamin Franklin, is one of our country’s oldest federal law enforcement agencies. Postal Inspectors have a long, proud, and successful history of fighting criminals who attack our nation’s postal system and misuse it to defraud, endanger, or otherwise threaten the American public. The Postal Inspection Service enforces more than 200 federal laws related to crime that adversely affects or fraudulently uses the U.S. Mail and postal system.
