Aiken South Carolina ZIP Codes

Aiken holds 6 ZIP codes, all inside one county and one postal prefix.

We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP. USPS delivery-type products are licensed, and no clean-rights source maps ZIP codes to neighbourhoods — so the Aiken codes above are listed without a column we would have to invent.

Scope every ZIP code recorded for Aiken. Source GeoNames US postal codes (2026-07 postal dump) and Census 2024 county Gazetteer (2024 Gazetteer). Updated 15 July 2026. ZIP codes are delivery-route groupings, not areas; the boundaries implied by any ZIP map are approximations.

Every Aiken ZIP code begins 298. Those first three digits identify the sectional center facility that processes mail for this part of South Carolina. Statewide that range covers 44 ZIP codes, so Aiken accounts for 14% of it.
