What We Do
The U.S. Postal Service OIG’s audits and reviews are designed to protect assets and revenue, ensure efficient and economical mail delivery, and safeguard the integrity of the postal system. We perform audits and reviews in compliance with standards published by the Comptroller General of the United States, the American Institute of Certified Public Accountants, the Public Company Accounting Oversight Board, the Institute of Internal Auditors, and the Council of the Inspectors General on Integrity and Efficiency.
Our mission is to conduct and supervise objective and independent audits and reviews of Postal Service programs and operations to:
- Prevent and detect fraud, waste, and misconduct;
- Promote economy, efficiency, and effectiveness;
- Promote program integrity, and
- Keep the Board of Governors, Congress, and Postal Service management informed of problems, deficiencies, and corresponding corrective actions.
Under the leadership of the Inspector General, the Assistant Inspector General for Audit (AIGA) is responsible for the Office of Audit. Deputy Assistant Inspectors General for Audit (DAIGAs) report to the AIGA and oversee audit programs focused on Mission Operations, Support Operations, Financial Accountability, and Revenue and Systems. The DAIGAs advise the AIGA on the major risks facing the Postal Service in their program areas and propose audits based on these risks and stakeholder concerns. The DAIGAs also maintain professional relationships with Postal Service executives to ensure open communication and full coverage of their issues and challenges.
Generally, our audit resources are aligned with those of the Postal Service vice presidents and major functional areas, allowing us to focus our efforts where there are the greatest potential risks and challenges to Postal Service management and operations.
