Key Facts
  • With 1,488 PO Boxes and 889 households, the post office serves 67% more boxes than local homes, accommodating seasonal residents who maintain year-round mail access
  • This is a PO Box Only Zone where no alternative mail delivery exists, despite limited street carrier routes serving some addresses
  • Over half of all housing units (52%, or 1,121 of 2,137 homes) are seasonal vacation properties, creating dramatic summer population swings
  • Median home values of $1,997,100 place Amagansett among the most expensive coastal communities in New York
  • One-third of workers (33.5%) work from home, well above national averages, suggesting remote professionals and consultants
  • With only 47 residents under 18 and a median age of 50.7, this is a retirement and second-home community rather than a family-oriented beach town

A Seasonal Community

Amagansett sits on the eastern tip of Long Island, New York, between East Hampton and Montauk. This isn't a year-round community. Of 2,137 homes, 1,121 (52%) are used seasonally, and only 889 are occupied year-round. The population of 2,062 swells dramatically during summer months when vacation homeowners return to the Atlantic coast.

Why PO Boxes Dominate

The Amagansett post office maintains 1,488 PO Boxes for just 889 households. That's a 1.67x adoption rate. Many second homeowners keep boxes year-round to receive mail when they aren't in residence. With a median home value of $1,997,100, these are affluent seasonal residents who maintain multiple properties. This is a PO Box Only Zone, meaning there's no alternative mail delivery method available.

Coastal Village Character

Street names tell the story of a historic coastal village. Main Street and Atlantic Avenue anchor the hamlet center. Montauk Highway (with 133 delivery records) is the primary corridor running east toward Montauk Point. Names like Marine Boulevard, Shore Road, and Shipwreck Drive recall the maritime heritage. Others like Fresh Pond Road, Cranberry Hole Road, and Red Dirt Road reference local geographic features.

Demographics of Affluence

Demographics show an older, educated, predominantly white population. Median age is 50.7 years. Of residents 25 and older, 62.3% hold bachelor's degrees or higher. The population is 85% white, with 16% Hispanic. Only 47 residents are under 18. This is a community of empty nesters and retirees, not young families.

Remote Work and High Incomes

Work patterns are unusual. Of employed residents, 33.5% work from home. Many are professionals, consultants, or writers who can work remotely from their beach homes. The median household income of $132,917 and per capita income of $106,282 place Amagansett well above national averages. This isn't a working-class beach town. It's an exclusive retreat.

Delivery Patterns

Delivery infrastructure combines urban and rural routes. Two city carrier routes (C routes) and one rural route (R route) serve the year-round population along 72 distinct streets. The limited street delivery doesn't cover all addresses, which is why PO Box adoption remains high even for permanent residents. General Delivery is available for those who need it.

Mailing to Amagansett

For year-round residents and seasonal homeowners alike, a PO Box is the standard mailing address:
