  • Public administration employs 82% of the workforce, mostly tribal government and North Slope Borough positions

Community Overview

Anaktuvuk Pass sits in the heart of Alaska's Brooks Range, the only inland Iñupiaq community in the North Slope Borough. The name means "place of caribou droppings" in Iñupiaq, and for good reason: this village of 425 people lies along the ancient migration route of the Western Arctic caribou herd. At 68 degrees north latitude, the community is 250 miles north of Fairbanks and accessible only by air.

Geographic Context and Isolation

This is a PO Box Only Zone. There's no alternative mail delivery across the 3,598 square mile territory. The post office uses a hybrid system with 5 PO Box records and 2 rural carrier routes serving Maptegak Street and Summer Street. With just 113 households spread across nearly 3,600 square miles, traditional street delivery infrastructure isn't practical in this remote Arctic location.

Population and Demographics

Three out of four residents (74%, or 315 of 425 people) are Alaska Native, making Anaktuvuk Pass one of Alaska's strongest Iñupiaq communities. Households average 3.8 people, nearly double the national norm, typical of Alaska Native extended family structures. The median age is 24.1 years, indicating a young population with deep roots in subsistence living and traditional culture.

Economic Context

Public administration employs 82% of the workforce, which means most jobs come from tribal government, the North Slope Borough, and local schools. Education is limited: just 4.5% of adults hold bachelor's degrees. Median household income is $83,250, supported by North Slope Borough oil revenue distributions and subsistence hunting. The cost of living is extreme in a village where everything arrives by air, yet median home values are $137,500 and median rent is $1,143.

Postal History and Mailing Information

The community uses "Anaktuvuk" as an accepted mailing alias (added in May 2005), though "Anaktuvuk Pass" remains the official post office name. The post office has served this village since before ZIP tracking began in October 2004, functioning as the lifeline for government documents, medications, supplies, and the rare packages that make it 250 miles beyond road access.

Street Name Patterns

Minimal Addressing

Only 2 streets with ZIP+4 records across 3,598 square miles, typical of remote Alaska Native villages with minimal addressing infrastructure.
