Who we are…

The U.S. Postal Inspection Service is the law enforcement arm of the U.S. Postal Service®. Our mission is to protect the Postal Service™, secure the nation’s mail system, and ensure public trust in the mail. We investigate criminal, civil, and administrative violations of postal-related laws, often using forensics and cutting-edge technologies. We work closely with other federal, state, and local law enforcement agencies and, over our long and storied history, have become recognized as one of the country’s most efficient and effective law enforcement organizations.

In fact, the history of the Postal Inspection Service goes back further than that of any other federal law enforcement agency, all the way to August 7, 1775, when Benjamin Franklin appointed the first Surveyor of Post Roads (the forerunner to the modern Postal Inspector). From solving stagecoach robberies over two hundred years ago to investigating cybercrime and identity theft today, the Postal Inspection Service has always been an integral part of American commerce and communication. Today, we continue to evolve—to meet new crimes and threats, to implement new crime-fighting technologies, and to catch the criminals who attack or misuse our nation’s mail system.
