Background

The Columbia Main Post Office is located in the Gateway District of the Central Area. This audit was designed to provide U.S. Postal Service management with timely information on potential scanning and mail delivery risks at the Columbia Main Post Office.

The delivery unit has 38 city routes which are delivered by 47 full-time carriers and 12 City Carrier Assistants. The unit also has nine rural routes delivered by eight full-time, seven Replacement Carriers, and six Assistant Rural Carriers. We chose the Columbia Main Post Office based on the number of stop-the-clock scans occurring at the delivery unit.

Our objective was to evaluate select mail delivery and customer service operations and determine whether internal controls were effective at the Columbia Main Post Office. We found issues related to package scanning and also the safeguarding of assets.
