Islesford sits on Little Cranberry Island, one of Maine's most distinctly seasonal communities. Of the 167 total housing units, 130 are vacation properties that sit empty most of the year. That's 78% seasonal vacancy, among the highest in coastal Maine. Only 30 households live here year-round, yet the post office maintains 123 PO Boxes.
The adoption rate of 4.1 boxes per household isn't about necessity. It's about affluence. Second homeowners need year-round addresses for property taxes, insurance documents, and seasonal deliveries. When your summer cottage is worth $402,900 (the median home value), you don't rely on a neighbor to collect your mail. You rent a box.
Main Street is the only named street in the ZIP+4 database, with just 4 delivery records. There's no street delivery here. The 11 businesses that operate during tourist season all use PO Boxes. So do the handful of lobstermen and artists who stay through winter. The post office building itself appears in the database as a named structure, the organizational center for an island that swells from 96 year-round residents to several hundred in July and August.
With only Main Street appearing in postal records, this reflects the minimal road infrastructure typical of small Maine islands. The single street with 4 delivery records serves primarily as an administrative designation rather than an active delivery route.
ZIP Code 04646 has 96 residents and 30 households (average 3.20 persons per household). The median age is 39.6 years, younger than the state (45.1) and about the same as the nation (38.8). The gender split is 47.9% male and 52.1% female, which is slightly lower than the national male share (49.1%), making this a female-majority area. Largest groups are White (92.7%, much higher than the national average of 61.6%) and Black or African American (1.0%, much lower than the national average of 12.4%); Hispanic or Latino residents make up 1.0%, which is much lower than the national average (18.7%).
