We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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 Union codes above are listed without a column we would have to invent.
Scope every ZIP code recorded for Union. Source GeoNames US postal codes (2026-07 postal dump) and Census 2024 county Gazetteer (2024 Gazetteer). Updated . ZIP codes are delivery-route groupings, not areas; the boundaries implied by any ZIP map are approximations.
How these codes cluster
Every Union ZIP code begins 293. Those first three digits identify the sectional center facility that processes mail for this part of South Carolina. Statewide that range covers 53 ZIP codes, so Union accounts for 2% of it.
