Postal Operations

While classified as a PO Box ZIP, the area does have one rural carrier route that provides street delivery along 5th St and Seantria St. Most mail still flows through the post office boxes, which function as the primary delivery method for this rural Georgia community. The postal facility's reach extends beyond Meldrim's compact 0.06-square-mile footprint to serve the broader rural area.

Street Name Patterns

Numbered Grid Limited Infrastructure

The minimal street network with only two streets receiving mail delivery reflects Meldrim's small size and reliance on PO Box service. The numbered grid pattern on 5th St suggests some traditional town planning, but the limited delivery infrastructure shows most residents depend on post office boxes.
