Community Overview

Claiborne sits on Talbot County's Eastern Shore of Maryland, a small waterfront community where the Chesapeake Bay shapes daily life. With 201 residents and a median age of 65.8 years, this is one of Maryland's older communities. Most residents are retirees who've chosen this quiet bayside location.

Postal Services

Mail arrives via two rural carrier routes covering 11 streets across 1.24 square miles. Despite its classification as a PO Box ZIP, Claiborne doesn't operate PO Boxes. Instead, all 71 residential delivery points receive direct rural carrier service. This unusual combination (Classified as a PO Box but with street delivery and zero boxes) reflects legacy postal database coding that doesn't match current operations.

A Waterfront Community

The housing stock tells the story of a compact waterfront community. Of 142 total housing units, 114 are occupied year-round, while 27 sit vacant for seasonal use. That's a 19% seasonal vacancy rate, modest for a Chesapeake Bay location. With 70 multi-family units and only 1 single-family home, Claiborne appears to be organized around waterfront condominiums or townhome developments rather than traditional single-family lots.

Local Character

Street names like Bayside Drive, Rich Neck Road, and Claiborne Landing Road point to the waterfront geography. The community is small enough that 11 streets handle all delivery, with Sherwood Manor Drive and Rich Neck Road each serving 6 addresses. Nearby communities include Mayo, Shady Side, and Highland Beach, all within 12 miles across the Bay.

Demographics

Per capita income stands at $50,158, with median home values of $395,800. About 47% of adults hold bachelor's degrees or higher. Everyone here was born in the United States. These numbers describe a comfortable, educated retirement community rather than a working-age population.

Mailing Information

For mailing purposes, use standard street addresses with Claiborne, MD 21624. There's no PO Box option and no need for one. Rural carriers handle all deliveries to waterfront homes and condominiums.
