Beirne sits along Highway 51 South in rural Clark County, Arkansas. This is a PO Box Only Zone, meaning there's no alternative mail delivery across the surrounding area. The post office maintains 16 PO Boxes for a local population of just 15 residents in 4 households. That 4-to-1 ratio tells the real story: people from surrounding rural areas without carrier delivery depend on the Beirne post office.
The community uses Highway Contract Route delivery (Route H001), typical of remote corridor communities where USPS contracts with carriers to serve scattered addresses along major roads. General Delivery service is also available, allowing people without permanent addresses to receive mail. With only one street in the ZIP+4 data (Highway 51 S with 2 delivery points), this isn't a traditional town with neighborhoods and subdivisions.
All 15 residents counted in the 2020 Census live in owner-occupied homes. Median age is 39.5 years. The population is entirely White, and there are 2 children under 18. The ZCTA boundary covers just 0.18 square miles, but the postal service area extends much further. The Beirne ZIP exists within the larger territory of ZIP 71743, which surrounds this point location.
No businesses are recorded in Census data for this ZIP. The post office itself is the primary presence, serving as a critical access point for mail, packages, and government documents for people scattered across the rural landscape who can't get delivery to their homes.
Only Highway 51 South appears in delivery records, with 2 delivery points along this rural route.
ZIP Code 71721 has 15 residents and 4 households (average 3.75 persons per household). The median age is 39.5 years, about the same as the state (38.8) and about the same as the nation (38.8). The gender split is 66.7% male and 33.3% female, which is much higher than the state male share (49.0%), making this a male-majority area. Largest groups are White (100.0%, much higher than the state average of 70.2% and well above the national average of 61.6%) and Black or African American (0.0%, much lower than the state average of 15.1% and well below the national average of 12.4%); Hispanic or Latino residents make up 0.0%, which is much lower than the national average (18.7%).
