Una is a small community in Spartanburg County, South Carolina, with just 286 residents living in an area of less than one-tenth of a square mile. Despite its compact size, the Una post office maintains 195 PO Boxes for only 89 households. That's a 2.19 adoption rate, meaning the post office serves more than twice as many boxes as local homes.
This is a PO Box Only Zone. There's no alternative mail delivery across the service area, so residents and surrounding communities rely entirely on the post office for mail access. While Una has some street delivery infrastructure (2 city carrier routes and 1 rural route covering streets like Sibley St), the PO Box system handles the majority of mail.
Una's demographics tell the story of a working-class community. Median household income is $26,979, and 72% of housing units are rentals (64 of 89 occupied homes). The median age of 28.4 years suggests a younger population. Transportation and warehousing employs a significant portion of the workforce (89 workers in ACS data), indicating Una's role in the region's logistics sector.
The housing stock is older, with 113 of 122 units built before 1939, and 96 mobile homes make up much of the community. Median gross rent is $681. Most delivery points are concentrated on Sibley St, which has 49 ZIP+4 records and includes multi-unit addresses. The compact geography and high PO Box adoption rate suggest Una functions as a regional mail access point for surrounding rural areas that lack their own postal facilities.
Delivery concentrated on Sibley St with 49 records including multi-unit addresses; other streets have minimal ZIP+4 presence.
