Stamp Stock Accountability Controls

Financial controls at postal retail units (retail units) are established and monitored by the Office of the Controller (Controller). We identified control issues during our past audits at selected retail units related to stamp stock shipments, single drawer accountability, and segmented inventory accountability. As a result of that work, the Controller advised they were strengthening controls over stamp stock accountabilities and upgrading financial controls to resolve the issues. The objective of our audit was to review the design and effectiveness of internal controls over stamp stock accountabilities used by the Controller to reduce financial control risks at U.S. Postal Service locations. Based on our review, we expanded our objective to include related controls used by other headquarters organizations.
