The Castle Rock Main Post Office (MPO) is in the Colorado/Wyoming District of the WestPac Area. This audit was designed to provide U.S. Postal Service management with timely information on potential scanning, mail delivery, and customer service operations risks at the Castle Rock MPO.
The unit has 33 city routes which are delivered by 46 city carriers. The unit also has 20 Contract Delivery Service (CDS) routes which are delivered by CDS route contract owners and their substitute employees. We chose the Castle Rock MPO based on the number of stop-the-clock (STC) 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 Castle Rock MPO, Castle Rock, CO.
We found delayed mail, inaccurate reporting of delayed mail, and improper scanning of packages.
