Tununak sits on Alaska's western coast, where the Bering Sea meets the Yukon-Kuskokwim Delta. This is one of Alaska's most isolated communities. The post office here doesn't just deliver mail—it's the only delivery infrastructure for 411 people spread across 77.8 square miles of tundra and coastal terrain.
The numbers tell the isolation story. There's no street delivery alternative. Residents either use the post office or have no mail service at all. Of the 87 occupied households, many house extended families, with 4.7 people per household on average. That's typical for Alaska Native communities, where multi-generational living is the norm, not the exception.
The ZIP code shows just two streets in the postal database: Airport Way and Island Drive. That's it. This isn't a place with subdivisions or numbered avenues. What road infrastructure exists serves basic community needs—getting to the airport and moving around the island terrain. For 95% of residents who are Alaska Native, the post office boxes represent the most reliable connection to services, government correspondence, and the outside world.
With a median household income of $49,063 and limited employment options (just 4 business establishments employing 40 people), the post office serves as an essential piece of infrastructure. The community is young, with a median age of 25.1 years, and those 28 children under 5 will grow up knowing PO Boxes as the standard way to receive mail. In Tununak, there's no alternative mail system to transition to—this is the system.
With just two streets in the postal database, Tununak's road infrastructure is purely functional—one route to the airport, one for island navigation. These aren't streets in the suburban sense but essential pathways in an isolated coastal community where the post office provides the only mail delivery system.
ZIP Code 99681 has 411 residents and 87 households (average 4.72 persons per household). The median age is 25.1 years, significantly younger than the state (35.6) and significantly younger than the nation (38.8). The gender split is 56.9% male and 43.1% female, which is much higher than the national male share (49.1%), making this a male-majority area. Largest groups are American Indian & Alaska Native (94.9%, much higher than the state average of 15.2% and well above the national average of 1.1%) and White (2.7%, much lower than the state average of 59.4% and well below the national average of 61.6%); Hispanic or Latino residents make up 0.2%, which is much lower than the national average (18.7%), and American Indian & Alaska Native share is much higher than both the state (15.2%) and national averages (1.1%).
