This isn't a counting error. It's what happens when seasonal property dominates. Of the area's 101 total housing units, 95 are classified as seasonal or vacation properties. That's 94% of all housing. Most owners don't live here year-round, but they need a mailing address that works every month of the year. A PO Box at the Nikiski post office solves that problem.
The numbers tell the rest of the story. Median household income reaches $133,057—well above Alaska's state average. Only 3 households are occupied full-time, giving the area a population-to-household ratio of 8.0. The post office serves Halbouty Road and Kenai Spur Highway, but most mail goes to boxes, not mailboxes. This is a place people visit, not where they settle.
With only 2 streets receiving carrier delivery, Nikiski's postal infrastructure focuses overwhelmingly on PO Box service. The streets that do exist—Halbouty Road and Kenai Spur Highway—are major corridors rather than residential subdivisions, reinforcing the seasonal, dispersed character of the area.
ZIP Code 99635 has 24 residents and 3 households (average 4.00 persons per household).
