Reliance is a small highway corridor community in Sweetwater County, Wyoming, with 303 residents spread across 86 square miles. Despite its classification as a PO Box ZIP code, Reliance has no PO Boxes at all. Instead, mail is delivered entirely via Highway Contract routes and one Rural route, serving 154 single-family homes along numbered streets that hint at the town's historic grid layout.
The community sits at the intersection of rural Wyoming isolation and highway accessibility. Main Street holds 28 delivery points, making it the primary corridor through town. Other streets follow a simple numbered grid: North Street, 1st through 6th Streets, and Reliance Road. This pattern suggests origins as a railroad or mining settlement, common in southwest Wyoming's energy-rich landscape.
With a median age of 42.6 years and 87% homeownership (112 owner-occupied homes versus 17 rentals), Reliance is a stable, working-class community. Employment data shows 48 workers in transportation and warehousing, pointing to the town's role along a major route. The housing stock is notably old: 101 of the 170 total units were built before 1939, and 21 are mobile homes. Per capita income of $29,354 and sparse economic data reflect the challenges of collecting statistics in very small communities.
Reliance's classification as a PO Box ZIP is a legacy designation that doesn't match current reality. The USPS classified this ZIP during an earlier era, but today's delivery system uses contract carriers to bring mail directly to homes. There's no post office building with boxes. It's simply a rural community where highway contractors handle the mail, covering vast distances across the high desert terrain of Sweetwater County.
The numbered street grid (1st through 6th Streets) and simple directional streets suggest a planned railroad or mining settlement from Wyoming's early development era.
ZIP Code 82943 has 303 residents and 129 households (average 2.35 persons per household). The median age is 42.6 years, older than the state (38.7) and older than the nation (38.8). The gender split is 55.8% male and 44.2% female, which is higher than the national male share (49.1%), making this a male-majority area. Largest groups are White (81.5%, much higher than the national average of 61.6%) and Hispanic or Latino (17.2%); Hispanic or Latino residents make up 17.2%, which is higher than the state average (10.2%).
