Austin is the state capital. Larger cities have many ZIP codes because each code follows mail delivery routes, not city limits.

Sample addresses

John Jackson 3333 Liberty Pl Beaumont, TX 77701
William Clark 2836 Mill Ave Waco, TX 76707
Priya Thompson 1436 Cedar Blvd Lubbock, TX 79402

These examples use real city and ZIP pairs with invented street lines, so they are safe for testing and documentation.

Tips for working with these ZIP codes

  • Store ZIP codes as text, not numbers, so the format stays consistent across states with leading zeros.
  • Texas spans more than one time zone (Central and Mountain). Use the ZIP code or county, not the state, to decide local time.
  • A quick sanity check: a valid TX ZIP code begins with one of the prefixes listed above.
  • City names in addresses are post office names. A suburb may share a ZIP code and city name with a nearby larger town.

Create realistic Texas addresses for testing, with real cities, counties and ZIP codes.
