Protecting USPS®

The Postal Inspection Service maintains a police force tasked with securing high-value Post Offices, facilities, and postal vehicles. These Postal Police Officers ® are on duty every hour of every day.

Protecting USPS® Employees

The safety and well-being of postal service employees is a top priority for the Postal Inspection Service. Postal Inspectors and Postal Police Officers work diligently to investigate and prevent instances of violence against our employees.

Illegal Narcotics

The Postal Inspection Service works aggressively to prevent the flow of illicit drugs and contraband through the mail stream, and takes all practicable measures to ensure the sanctity and security of the U.S. Mail. The Inspection Service is central to the strategy to eliminate the mailing of opioids and other illicit drugs and it works closely with other law enforcement agencies, including U.S. Customs and Border Protection, to share intelligence, coordinate cases and conduct joint enforcement operations. As part of this effort, the Inspection Service has developed tools to identify those who attempt to hide behind the secrecy of the dark web and cryptocurrency to misuse the postal network.
