Adak sits in the western Aleutian Islands of Alaska, roughly 1,200 miles southwest of Anchorage. This is one of the westernmost communities in the United States. The island spans 335 square miles but holds just 171 residents. Most of them rely on the post office because Adak is a PO Box Only Zone with no alternative mail delivery anywhere on the island.
The community traces back to World War II and the Cold War, when the U.S. Navy operated a major base here. After the base closed in 1997, the population crashed from thousands to a handful. Today, 57 of the 171 residents (33%) live in group quarters, likely worker housing for the remaining airport and fishing operations. Transportation employs 89 workers, the dominant industry by far.
Housing tells the story of Adak's decline. Of 244 housing units on the island, only 62 are occupied. That's a 75% vacancy rate. The abandoned military infrastructure includes barracks, family housing, and support buildings now sitting empty. Median home value is just $78,000, reflecting the isolation and limited market.
The post office maintains 29 PO Boxes for 62 households, a 47% adoption rate. General Delivery is also available for transient workers and visitors. With one recorded street (Mechanical St) in the entire ZIP code, the old military grid has no formal addressing system for carrier delivery. Every piece of mail goes through the post office.
Adak's population is diverse for such a remote place. 36% are White, 22% are Alaska Native, 16% identify as two or more races, and 11% are Some Other Race. The median age of 38.8 suggests a working-age population rather than retirees. Just 3 children under 18 and 7 residents over 65 live here. This isn't a place for families or retirement.
Only one street appears in postal records. The former military base's road grid isn't formally addressed for mail delivery.
ZIP Code 99546 has 171 residents and 62 households (average 1.84 persons per household). The median age is 38.8 years, older than the state (35.6) and about the same as the nation (38.8). The gender split is 57.9% male and 42.1% female, which is much higher than the national male share (49.1%), making this a male-majority area. Largest groups are White (35.7%, much lower than the state average of 59.4% and well below the national average of 61.6%) and Hispanic or Latino (22.2%); Hispanic or Latino residents make up 22.2%, which is much higher than the state average (6.8%), and American Indian & Alaska Native share is much higher than the national average (1.1%).
