The numbers tell the story clearly. This ZIP maintains 59 PO Boxes for 21 occupied households. That's an adoption rate of 2.81, meaning nearly three boxes exist for every local household. The math doesn't work unless you understand the geography. People drive in from properties along the Entiat River Road and the surrounding national forest lands where no carrier routes exist. Some boxes serve seasonal cabins. Others belong to ranchers whose properties stretch across multiple sections. Still others support households in the even more remote areas upriver where Ardenvoir represents the nearest postal service.
The ZIP classification shows "P" for PO Box only, and that designation reflects reality here. With carrier route type listed as rural and just two street delivery points recorded in the database, this isn't a community where you can opt for curbside mail. The enclosing ZIP is 98822 (Entiat), but even that doesn't help residents here. If you live along the upper Entiat River drainage, you're getting a PO Box in Ardenvoir or you're not getting consistent mail service.
Census data from 2020 counted 31 total housing units, with only 21 occupied year-round. That leaves 10 units vacant, and in a mountain valley known for recreation access, those likely represent seasonal cabins and hunting camps. The median age sits at 42.7 years, and the population is overwhelmingly white (61 of 76 residents). Median household income reaches $43,650, which is modest but not poverty-level for rural Washington. The area covers just half a square mile of land despite the vast service territory, because the ZIP boundary follows the narrow valley floor where the post office and the handful of permanent structures sit. This is classic North Cascades settlement: a tiny core serving a broad backcountry reach.
Street names reflect the area's defining geographic feature: the Entiat River drainage system. With only two named streets in the delivery database and most access via the Entiat River Road corridor, the addressing system shows minimal urban development. This is backcountry territory where property descriptions often rely on forest service roads and milepost markers rather than traditional street addresses.
ZIP Code 98811 has 76 residents and 21 households (average 3.62 persons per household). The median age is 42.7 years, older than the state (38.1) and older than the nation (38.8). The gender split is 72.4% male and 27.6% female, which is much higher than the national male share (49.1%), making this a male-majority area. Largest groups are White (80.3%, much higher than the state average of 66.6% and well above the national average of 61.6%) and Asian (7.9%); Hispanic or Latino residents make up 3.9%, which is much lower than the national average (18.7%).
