The Dakota Central Processing and Distribution Center, a major USPS mail processing facility, operates under dedicated ZIP code 57399 in Huron, South Dakota. This 68,000-square-foot facility employs approximately 62 workers and handles mail sorting, distribution, and shipping operations for central South Dakota. One of only three processing facilities in the state (alongside Sioux Falls and Rapid City), Dakota Central serves as a regional hub for mail moving through the Great Plains.
Located in Beadle County, the facility processes letters, flats, and packages for the surrounding region. In 2025, following advocacy by South Dakota's congressional delegation, USPS confirmed the facility would retain its local mail processing operations rather than shifting them to Fargo. The Postal Service announced plans to invest up to $3 million to upgrade Dakota Central as a Local Processing Center. This dedicated ZIP has served the facility for over two decades. Huron is the valid mailing city.
