What We Do

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 almost $68 billion in revenue, the Postal Service is at the core of a more than $1.3 trillion mailing industry that employs more than 8 million people. The nearly 487,000 employees of the Postal Service compose one of the largest civilian federal workforce in the country.

Delivering more than 155.4 billion pieces of mail yearly to 154 million delivery points and operating 31,000 postal facilities, America’s postal system is one of the government’s most trusted entities. The USPS OIG, an independent agency within the Postal Service under the general supervision of nine presidentially appointed governors, employs more than 1,125 auditors, investigators, and professional support personnel stationed in more than 100 offices to meet the challenge of preserving this trust.

 

Our Mission

The OIG achieves its mission of helping maintain confidence in the postal system and improving the Postal Service’s bottom line through independent audits and investigations. Audits of postal programs and operations help to determine whether the programs and operations are efficient and cost-effective. Investigations help prevent and detect fraud, waste, and misconduct and have a deterrent effect on postal crimes.
