The United States Postal Service Office of Inspector General (USPS OIG) is an independent federal oversight agency established in 1996 to ensure accountability and efficiency in USPS operations. It was created to address concerns about waste and misconduct within USPS law enforcement. The agency has grown from 10 employees to over 1,000 and operates separately from the USPS Postal Inspection Service. The USPS OIG's mission is to maintain public confidence in the postal system and enhance USPS's financial performance through independent audits, investigations, and research. It conducts audits of USPS programs and operations, investigates fraud and misconduct, and produces research and insights on various topics affecting the postal service. The agency also oversees IT infrastructure and analytics to improve operational efficiency. Key components of the USPS OIG include the Office of Audit, Office of Investigations, and the Research and Insights Solution Center.
