Our Work
The OIG plays a key role in maintaining the integrity and accountability of America’s postal service, its revenue and assets, and its employees.
With more than $78 billion in revenue, the Postal Service is at the core of a nearly $1.6 trillion U.S. mailing industry that employs approximately 7.3 million people. The more than 635,000 USPS employees compose one of the country’s largest civilian federal workforces.
Delivering approximately 127 billion pieces of mail yearly to almost 165 million delivery points using a fleet of more than 236,000 vehicles and operating more than 31,000 postal facilities, America’s postal system is one of the government’s most trusted entities.
The OIG, an independent agency within the Postal Service under the general supervision of nine presidentially appointed governors, employs more than 1,000 auditors, investigators, and professional support personnel stationed in more than 90 offices across the country.
Every day they work to preserve this trust by detecting and preventing fraud, waste, and abuse in USPS programs and operations.
