Sidnaw is a remote community in Michigan's Upper Peninsula, where PO Boxes serve as the only mail delivery option across 75 square miles of forested terrain. The post office maintains 76 PO Boxes for 60 year-round households, with the extra capacity serving seasonal residents who occupy the area's many vacation properties.
This is a retirement and vacation community with one of the oldest populations among Michigan's small towns. Median age is 65.7 years, and all 60 occupied homes are owner-occupied with zero renters. The population of 104 translates to just 1.7 people per household, typical of retiree couples and single seniors.
Seasonal vacancy defines the community's rhythm. Of 191 total housing units, 118 sit vacant most of the year, used for recreation or occasional visits. That's 62% seasonal occupancy. In summer, the population likely doubles or triples as vacation homeowners arrive from downstate Michigan and neighboring states.
Rural carrier routes serve the scattered homes along roads like State Highway M28, Lake 13 Road, and Sidnaw Road. Street names reference local lakes (Crystal Lake, Estes Lake) and the area's logging heritage. Two rural routes cover the territory, but there's no city carrier delivery. For most residents, the trip to the post office in the small village center is the main reason to leave home.
This is a PO Box Only Zone. There's no alternative mail delivery anywhere in the territory. Residents drive to the Sidnaw post office for packages, prescriptions, and all mail services. The median home value of $83,800 and median household income of $57,500 indicate a modest, working-class retirement community, not a wealthy resort area.
All mail must be addressed to a PO Box:
