Texas has 1,990 ZIP code areas, more than any other state, running from 73960 in the Panhandle to 79938 at the El Paso line. Houston has 97 of them, the largest block in the state, but that is under 5% of the total. Most Texas ZIP codes start with 75 to 79, and the third digit narrows down the region.
Note: many ZIP listing sites I found contain neighbourhood errors, so I’ve used well-known ZIP-to-area matches. ZIP boundaries and assignments change, so confirm any code you publish with the USPS lookup tool.

How to Find the Right Texas ZIP Code
- Use the USPS ZIP Code Lookup with the full street address. It is the authoritative source.
- Check recent mail or a utility bill for the ZIP printed on your address.
- Know that the city name may differ. Many suburbs and unincorporated areas, such as Cypress, use a nearby city name in their mailing address.
- Don’t rely on real estate or listing sites alone. They may lag behind USPS changes.
- Use ZIP+4 for precision. Nine-digit codes pinpoint delivery routes, buildings, or floors.
- Remember P.O. Box ZIPs. Some ZIP codes, like Austin’s 73301, are used only for P.O. boxes or specific organisations.
