A Gold Rush Town at the End of the Road

Skagway sits at the northern end of Alaska's Inside Passage, where 1,240 year-round residents occupy a territory of 445 square miles. This is a PO Box Only Zone. There's no alternative mail delivery across this mountainous landscape. The Skagway post office maintains 807 PO Boxes for 531 occupied homes, a 1.52 adoption rate that extends beyond the town itself to serve surrounding areas accessible only by the Klondike Highway and Dyea Road.

Street Names Preserve Gold Rush History

The street grid tells Skagway's story as a historic gold rush town turned cruise ship port. Broadway, the main thoroughfare with 36 delivery points, runs through downtown past Victorian-era buildings that once housed stampeders heading to the Yukon goldfields. State Street and Main Street form the commercial core, while numbered avenues (1st through 23rd) climb the hillside in a grid established in the 1890s. The Klondike Highway, with 21 delivery addresses, connects Skagway to Canada's Yukon Territory along the historic White Pass route.

Seasonal Community, Tourism Economy

This isn't primarily a year-round residential community. Of 760 total housing units, 136 are used seasonally, giving Skagway an 18% seasonal vacancy rate. The town's population swells dramatically during cruise season (May through September), when over a million visitors pass through this port of 1,240 permanent residents. That tourism economy shapes everything: 481 workers are employed in transportation (38% of the workforce), and per capita income reaches $53,798.

Rural Mail Delivery

Rural carrier routes serve the scattered residences outside downtown. Two rural routes handle 294 ZIP+4 records across roads like Dyea Road (leading to a Klondike ghost town), Liarsville Road, and residential streets stretching along the Taiya Inlet. Multi-unit buildings with designations like UNIT and APT concentrate on Broadway, State Street, and the numbered avenues, housing both permanent residents and seasonal workers. The post office is located in downtown Skagway at the Post Office facility.

Demographics

Demographics show a working-age population with median age 40.7 years. The community is 86% White (1,070 of 1,240 residents), with 108 Hispanic or Latino residents. Median household income of $78,594 is above the national average, though housing costs match: median home value is $430,000. Owner-occupied homes (297) slightly outnumber rentals (234). Educational attainment is moderate, with 28% holding bachelor's degrees or higher.
