About United States Postal Inspection Service
The United States Postal Inspection Service (USPIS) is the federal law enforcement arm of the United States Postal Service. It supports and protects the United States 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 United States Mail, the postal system, or postal employees. With roots going back to the late 18th century, the USPIS is the country's oldest continuously operating federal law enforcement agency.
