During the week of June 2, 2025, we performed a self-initiated audit at the St. Louis Processing and Distribution Center (P&DC) and Network Distribution Center (NDC) and seven delivery units serviced by the two plants. The delivery units included the Ballwin, O’Fallon, and St. Charles Main Post Offices, Maryville Gardens and Southwest Stations, and the Clayton and Creve Coeur Branches in the St. Louis, MO area.
We issued individual reports for the seven delivery units, P&DC, and NDC. We issued another report summarizing the results of our audits at all seven delivery units with specific recommendations for management to address.
The audit team identified deficiencies in all five areas we reviewed affecting mail delivery and property conditions.
We identified deficiencies in all of the areas we reviewed that affected the efficiency of operations at the St. Louis P&DC and NDC. We also identified other issues related to the security of registry items at the P&DC and safety and security at the NDC.
