ZIP code 49786 was assigned to the Hiawatha Correctional Facility, a Michigan Department of Corrections prison that operated in Chippewa County from 1989 to 2009. Unlike the neighboring Kinross Correctional Facility which occupied converted Air Force buildings, Hiawatha was purpose-built as a prison on former Kincheloe Air Force Base land. The postal designation dates back over two decades.
The facility closed in August 2009 as part of a statewide MDOC reorganization that eliminated 6,400 prison beds across Michigan. After sitting dormant for six years, the Hiawatha campus reopened in October 2015 as the relocated Kinross Correctional Facility, which now uses a different ZIP code. With zero active ZIP+4 codes and no Census data, ZIP 49786 appears to remain in the postal system as a legacy designation. Kincheloe, Sault S Marie, and Sault Sainte Marie are the valid mailing city names on file.
