South Houston Texas ZIP Codes

South Houston holds a single ZIP code.

We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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 South Houston codes above are listed without a column we would have to invent.

Scope every ZIP code recorded for South Houston. 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 South Houston ZIP code begins 775. Those first three digits identify the sectional center facility that processes mail for this part of Texas. Statewide that range covers 71 ZIP codes, so South Houston accounts for 1% of it.
