Fishers Island sits just off the Connecticut coast but belongs to New York's Suffolk County. This unusual geographic quirk gives the island a Connecticut ZIP code (06390) despite being part of New York State. The island spans 4.2 square miles of land surrounded by 11.6 square miles of water, creating a distinct island community accessible only by ferry or private boat.
With 606 total housing units but only 180 occupied year-round, Fishers Island is primarily a seasonal retreat. 414 homes (68% of all housing) sit vacant most of the year, used only during summer months. The year-round population of 422 residents swells dramatically when seasonal homeowners arrive.
The Fishers Island post office maintains 509 PO Boxes for just 180 year-round households. That's a 2.83 adoption rate, nearly three times the local population. This high ratio makes sense: seasonal homeowners keep boxes open all year to receive tax bills, property notices, and packages. Year-round residents use PO Boxes because this is a PO Box Only Zone. There's no street carrier delivery on the island.
The island uses rural route delivery (337 addresses on two rural routes) for packages and oversized mail, but standard letters go to PO Boxes. Street names like Clay Point Road, Peninsula Road, Isabella Beach Road, and Oceanic Avenue tell the story of a coastal community built around beaches, harbors, and waterfront living.
The year-round population skews older. Median age is 50.6 years. Only 8 residents are under 18, and just 11 are between 18 and 24. This isn't a family community. It's a place where older adults live permanently and where seasonal residents (often retirees or professionals) maintain second homes.
Of the 422 year-round residents, 359 (85%) are white. The island has small Asian (11) and Hispanic (60) populations, with minimal racial diversity otherwise. Educational attainment is high: 39.5% of adults hold bachelor's degrees or higher. Median household income is $51,964, with per capita income at $35,883.
Fishers Island has maintained this pattern for decades. The ZIP code dates to before October 2004 (when USPS tracking began), and the island's character has remained consistent. The post office accepts mail addressed to both "Fishers Island" and the shorter "Fishers Isle" (added as an alias in May 2005).
Economically, the island supports 42 business establishments employing 252 people. Many of these workers commute to the island by ferry, since employment (252 jobs) exceeds the working-age population. The island's economy runs on hospitality, property management, and services for seasonal residents.
All mail to Fishers Island residents requires a PO Box. Use this format:
