Hyampom sits deep in Trinity County's backcountry, where 304 residents are scattered across 195 square miles of mountainous terrain. This isn't a town in the traditional sense. It's a rural postal service area covering remote valleys and ridges along the South Fork Trinity River.
There's no alternative to PO Boxes here. Hyampom is classified as a PO Box Only Zone, meaning street delivery doesn't exist across this vast territory. The post office maintains 133 boxes for 146 households. That's a 91% adoption rate. Nearly everyone relies on the post office for mail, packages, and essential deliveries that won't reach isolated homes.
Rural carrier routes serve what few street addresses exist, but most residents make the trip to town. Street names like Lower South Fork Road, Forest Service Road, and Hyampom Road trace the river valleys and Forest Service land that dominates the landscape. This is logging and ranching country, where distances between neighbors are measured in miles.
The community skews older and working class. Median age is 47, and per capita income sits at just $8,273. About 35% of homes were built before 1939, testament to Hyampom's longevity as a mountain settlement. The population is 83% White, with small Hispanic (11%) and Asian (3%) populations.
Hyampom has been here since before the postal service started tracking ZIP introduction dates (listed as before October 2004 in records, but the community is far older). It serves as the mail hub for one of California's most remote corners, where Trinity National Forest and steep terrain keep modern development at bay.
