About ZIP Code 99753

Koyuk sits on the Norton Sound coast in western Alaska, 171 air miles northwest of Nome. The 312 residents here are overwhelmingly Inupiaq, with 90% of the population identifying as Native American. That makes this one of Alaska's most culturally homogenous communities, and the post office serves as a critical lifeline for daily life.

This isn't just a PO Box ZIP. It's the only mail system for 5.1 square miles of isolated coastal territory. The post office maintains 50 PO Boxes for 91 households, an adoption rate of 55%. There's no alternative. The nearest neighboring ZIP with street delivery doesn't exist in this region. Rural carrier Route R serves the single documented street, Birch Street, but the community's geographic isolation makes PO Box service the primary option for most residents.

The population density tells its own story. With 312 people living across 5.1 square miles, that's just 61 people per square mile. Extended families are common here, with a population-to-household ratio of 3.4, higher than the national average of 2.5. The median age is 26.3 years, indicating a relatively young population that's sustaining this coastal community.

Koyuk's economy reflects its remote location and subsistence traditions. The median household income is $34,250, well below Alaska's state median. Only 2 people work from home, and unemployment sits at 4.3%. Seven businesses operate here, employing 13 people. The median home value is $97,200. This isn't a place people move to for jobs. It's a community rooted in tradition, location, and kinship.

Street Name Patterns

Minimal Street Infrastructure Single Documented Street
