The community sits on a narrow spit of land where the Aleutians curve toward Russia. Cold Bay covers 42 square miles, but that doesn't capture the service area. Native residents make up 56% of the population here. Extended families are common, with 2.2 people per household reflecting multi-generational living patterns typical of Alaska Native communities. The median household income of $111,250 seems high, but costs here run three times the national average. Everything arrives by air or seasonal barge.
Street delivery doesn't exist in the traditional sense. The ZIP contains just three named roads: Farnester Avenue, Nelson Lagoon Road, and Letty Avenue. One rural carrier route handles what limited physical delivery occurs. Most mail goes to boxes at the post office, a building that serves as a daily gathering point during the brief summer and brutal winters when wind chills can hit 40 below. For communities this remote, the PO Box isn't a limitation. It's the lifeline that works when storms ground flights for days.
The postal infrastructure here supports more than mail delivery. With 32 businesses operating despite the tiny population, Cold Bay functions as a service center. Seventeen establishments employed 35 people as of the last business census. Many work in aviation support, fishing logistics, or government services. The post office maintains service to named buildings like the one designated simply as "Postmaster" in ZIP+4 records, the administrative center for this far-flung operation. When you're closer to Siberia than Anchorage, reliable mail service matters in ways most Americans never consider.
With only three named streets in the entire ZIP code, Cold Bay's road system reflects its role as a small but strategic outpost. Nelson Lagoon Road hints at the regional connections this post office maintains, serving communities dozens of miles away. The limited street infrastructure shows why PO Boxes are the only practical mail delivery method in this remote corner of the Aleutians.
