The U.S. Postal Service’s mission is to provide timely, reliable, secure, and affordable mail and package delivery to more than 160 million residential and business addresses across the country. The U.S. Postal Service Office of Inspector General (OIG) reviews delivery operations at facilities across the country and provides management with timely feedback in furtherance of this mission.
This interim report presents the results of our self-initiated audit of delivery operations and property conditions at the Grand Shelby Carrier Annex in Detroit, MI (Project Number 26-087-1). The Grand Shelby Carrier Annex is in the Michigan 1 District of the Central Area and serves about 19,798 people in ZIP Codes 48208, 48216, and 48226, which are considered urban areas.
We judgmentally selected the Grand Shelby Carrier Annex primarily based on the number of C360 delivery-related inquiries, Leg 1 and Leg 3 failures, and undelivered route data.
