United States Postal Inspection Service
The United States Postal Inspection Service (USPIS), or the Postal Inspectors, is the federal law enforcement arm of the United States Postal Service. It supports and protects the U.S. Postal Service, its employees, infrastructure, and customers by enforcing the laws that defend the United States' mail system from illegal or dangerous use. Its jurisdiction covers any crimes that may adversely affect or fraudulently use the U.S. Mail, the postal system or postal employees. With roots going back to the late 18th century, the USPIS is the oldest continuously operating federal law enforcement agency.
