Wilson Creek is a small rural community in central Washington's Grant County, where PO Boxes provide the only option for mail delivery across 79 square miles. With a population of 259 spread across a vast agricultural landscape, this isn't a place where mail carriers drive residential routes. The post office maintains 149 PO Boxes for 119 households, a rate of 1.25 that accounts for both local residents and people from surrounding farms and ranches.
This is a PO Box Only Zone. There's no alternative delivery method for the territory. Two rural carrier routes handle what limited delivery exists, but the 35 streets in the ZIP+4 database serve primarily as location identifiers rather than carrier routes. Main Street, Railroad Street, and numbered streets like 1st through 8th form the small town center, while roads with alphanumeric names (Road Q NE, Road R NE) serve the surrounding agricultural area.
At a median age of 50.5, Wilson Creek skews older than most of Washington. The community of 259 includes just 9 residents under 18. Homeownership stands at 80% (95 of 119 occupied homes). Nearly 40% of workers (5 out of 13 counted) work from home, a pattern common in remote rural areas where employment options are limited. The median household income of $51,250 and median home value of $184,200 indicate a modest, working-class community.
With only 4 business establishments employing just 3 people, Wilson Creek functions primarily as a residential and agricultural service point. The post office serves as one of the few public facilities in town, handling mail for local residents and the surrounding farming territory.
