Mackinac Island sits in the Straits of Mackinac between Michigan's Upper and Lower Peninsulas. This 3.8 square mile island is one of America's most unusual vacation communities. No cars are allowed. Transportation is limited to horse-drawn carriages, bicycles, and foot traffic, making the post office the only practical way to receive mail and packages year-round.
The island's 817 PO Boxes serve a year-round population of just 583 residents living in 293 households. That's a 2.79x adoption rate. The math tells the story: seasonal homeowners, summer workers, and businesses maintain boxes even when they're not on the island. This is a PO Box Only Zone. There's no alternative delivery method despite the presence of one rural carrier route serving a handful of addresses.
With 687 vacant homes out of 980 total housing units, 70% of the island's housing sits empty for much of the year. Of those vacant properties, 417 are seasonal homes. The population swells dramatically from late spring through early fall when tourists arrive by ferry and seasonal residents open their Victorian cottages. Median home values of $834,600 and a median age of 48 years point to an affluent vacation community rather than a working-class town.
Street names tell the island's dual story. Market Street and Main Street anchor the downtown commercial district where 98 businesses employ 482 people. But roads like Fort Holmes Road, British Landing Road, and Garrison Road recall the island's military history as a strategic Great Lakes outpost. The presence of M-185, Michigan's only state highway where motor vehicles are banned, and South Bike Trail confirm the car-free character that defines modern Mackinac Island.
The tourism economy dominates employment. Of the island's workforce, 95 people work in accommodation and food services. That's 45% of total employment serving the hundreds of thousands of visitors who arrive each summer. Another 15 work in public administration, likely managing Mackinac Island State Park, which covers 80% of the island's land area. The median household income of $100,125 is well above Michigan's average, supported by tourism dollars and seasonal business ownership.
The post office operates year-round while the island's population fluctuates wildly. Winter brings ice and isolation, when the 583 permanent residents rely on PO Boxes for prescription medications, online orders, and connection to the mainland. Summer transforms the village into a bustling resort where thousands of seasonal workers and visitors need mail access. The ferry that's required to reach the island from Mackinaw City or St. Ignace makes PO Box service not just practical but necessary.
Street names combine commercial tourism (Market, Main) with military history (Fort Holmes, British Landing, Garrison) and car-free transportation (M-185, Bike Trail).
