Community Overview

Angoon sits on the west coast of Admiralty Island in Southeast Alaska's Inside Passage. This Tlingit community of 364 residents occupies a vast 895 square mile territory accessible only by boat or floatplane. Of the population, 286 people (79%) are Alaska Native, making this one of Alaska's predominantly indigenous communities.

Why PO Boxes Are Essential

This is a PO Box Only Zone. No alternative mail delivery exists across the entire territory. The post office maintains just 9 PO Boxes for 136 households, an unusually low adoption rate of 0.066. This doesn't mean residents don't use the post office. Instead, the ZIP+4 data shows 2 rural carrier routes serving the community, with street names like Ravenbeaver Way, Aandeinatt Street, and Big Dog Salmon Way marking the limited road network.

Geographic Context

The geographic isolation shapes everything. Angoon isn't connected to Alaska's highway system. Mail arrives by ferry or air. The 895 square mile territory includes Admiralty Island wilderness, home to one of the world's densest brown bear populations. The 202 housing units include 50 seasonal homes (25%), used by subsistence hunting and fishing families who move seasonally.

Economic Context

Work centers on public administration and transportation. Of the employed workforce, 70 people work in public administration (mostly tribal government and Alaska Native corporations) and 63 in transportation, warehousing, and utilities (ferry operations, floatplane service). Median household income is $45,938. Median home value is $191,700. Only 14% of adults hold bachelor's degrees, but this reflects the community's subsistence-based economy rather than educational opportunity.
