Cranberry Isles sits off the coast of Maine near Mount Desert Island and Acadia National Park. This small archipelago includes Little Cranberry Island, Great Cranberry Island, and several smaller islands in Hancock County. The 2.2 square miles of land support a population that swells dramatically from summer to fall.
With 186 total housing units but only 41 occupied year-round, 72% of homes sit vacant most of the year, awaiting seasonal residents. Winter population stands at just 64 people, but median age of 56.3 years and 95% homeownership point to an established community of retirees and summer residents who have deep ties to the islands.
The Cranberry Isles post office maintains 79 PO Boxes for 41 year-round households. That's 1.93 boxes per household. This reflects the island's dual population: year-round lobstermen and caretakers alongside seasonal homeowners who maintain boxes to receive mail during their months away. There's no alternative. This is a PO Box Only Zone, and ferry access makes street delivery impractical.
Mail arrives via two rural carrier routes serving streets with names like Cranberry Road, Ocean Road, Boat Yard Drive, and Frenchman Bay. These routes wind across the small islands, delivering to the 80 residential delivery points and 12 businesses that serve both populations. Median home values of $400,000 and median household income of $68,000 reflect the island's appeal to those seeking Maine coast seclusion.
Of the 56 adults, 49% hold bachelor's degrees or higher, and 12% work from home. The 7 business establishments employ 17 people. Transportation and warehousing accounts for significant employment (17 workers), likely including ferry operations and marine services that connect the islands to the mainland. Everyone here was born in the United States. Two people rent. The rest own their homes outright or with mortgages.
Mail sent to Cranberry Isles, ME 04625 should use either a PO Box number or a street address with rural route designation. The accepted alias "Cranberry Is" (added May 2005) may also be used for the city name. Given the island location and seasonal population, PO Boxes ensure reliable mail receipt year-round.
Street names reference the island's cranberry heritage, coastal location, and connection to Frenchman Bay.
ZIP Code 04625 has 64 residents and 41 households (average 1.56 persons per household).
