Twin Mountain sits in the heart of New Hampshire's White Mountains, where 713 residents live across 48.7 square miles of Coos County. The median age here is 56 years, which is notably higher than most communities and points to a retirement-friendly population. With a population-to-household ratio of 2.17, most homes house couples or individuals rather than larger families.
The post office maintains 388 PO Boxes for 328 households, creating an adoption rate of 1.18. This means the Twin Mountain post office serves beyond just the immediate residential area, providing mail access for vacation property owners and surrounding rural locations. About 35% of the housing stock (184 of 532 units) sits vacant for seasonal use, showing the dual character of this community: year-round residents plus seasonal visitors drawn to the White Mountains.
Mail delivery follows a mixed pattern. Most addresses receive rural carrier service (146 ZIP+4 records), with limited city carrier service (2 records). The 55 street names tell the story of mountain living: Presidential View Drive, Old Cherry Mountain Road, Moose Lane, and Sugar Loaf Drive. Major routes include US Route 3, Route 115, and Route 302, which connect the community to the broader region.
Twin Mountain isn't a PO Box Only Zone, so street delivery exists alongside PO Box service. However, many residents prefer PO Boxes for convenience and reliability in a rural mountain setting. The median household income is $78,750, with home values at a median of $229,100. About 21% of workers operate from home, a pattern common in scenic rural areas that attract remote professionals and retirees.
Street names emphasize the White Mountains setting with routes named for geographic features like Cherry Mountain and Presidential peaks, plus nature-themed roads.
ZIP Code 03595 has 713 residents and 328 households (average 2.17 persons per household).
