Michigan 1 District: Delivery Operations
During the week of May 5, 2026, we performed a self-initiated audit at the Detroit Processing and Distribution Center (P&DC), and three delivery units serviced by the P&DC. The delivery units included Grand Shelby Carrier Annex, Gratiot Station, and Strathmoor Station Detroit, MI.
We issued individual reports for the three delivery units and one report for the P&DC. We will also issue another report summarizing the results of our audits at all three delivery units with specific recommendations for management to address.
The audit team identified deficiencies in five areas we reviewed affecting mail delivery and property conditions at the three delivery units.
