We do not publish a delivery type (standard, PO box, unique) or a neighbourhood for each ZIP.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

Scope every ZIP code recorded for Austin. 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

Those first three digits identify the sectional center facility that processes mail for a region, and Austin does not sit inside just one of them: its codes are split between 2 prefixes, so the city is served by more than one processing centre.

How Austin’s ZIP codes divide across the three-digit prefixes, with each prefix’s statewide size for scale.
