In the 1950s, leaders and residents of Bay, Saginaw and Midland counties asked state authorities for local institutions of higher education. A college district was established in 1957 and Delta College opened in September 1961.
A post office named "University Center" was opened on July 16, 1961 to serve the institutions. The ZIP code is designated as unique by the postal service, indicating that it is "used for a specific company or organization." SVSU lies entirely within Saginaw County's Kochville Township, and Delta College lies entirely within Bay County's Frankenlust Township, but both institutions are served by the University Center ZIP code. Sometimes there are certain instances that SVSU is considered to be part of the Saginaw ZIP code 48604. Similarly, Delta College is sometimes considered to be part of the Bay City ZIP Code 48706.
