U.S. Postal Inspection Service (USPIS)
The USPIS is the law enforcement, crime prevention and security arm of the U.S. Postal Service. Its postal inspectors keep the mail free from criminal attacks, and they are trained to ensure mail is safe from biological, chemical, radiological or potentially explosive substances. The USPIS supports intellectual property rights enforcement by partnering with CBP officers and ICE special agents to conduct interdictions and criminal investigations at five critical airports across the country. Postal inspectors are members of numerous federal taskforces that halt the flow of counterfeit financial instruments, pharmaceuticals and other commodities from entering this country. Postal inspectors are also coordinators of Operation Stamp Out, an IPR Center-sponsored campaign to interdict counterfeit postal money orders and other financial instruments shipped to the United States.
