Texas County Map with Zip Codes
A Texas county map with zip codes mixes two different layers. County outlines are not zip codes, and neither one is a parcel map.

A Texas county map with zip codes puts two layers on one picture: the state's 254 county outlines, and postal zip codes. They do not match. A zip code can cross a county line. A county contains many zip codes. Neither layer is a lot line.
Texas is large enough that the county name is the first thing you need. After that, the parcel map comes from that county's appraisal district or GIS office, not from the zip code.
Use each map for what it is
- The county outline answers "which county is this town in?"
- The zip code answers "how does the post office group this delivery area?"
- The parcel viewer answers "which tax lot is this, and how does the county draw it?"
Open the parcel and lot-line map
- Start at the Platbookmapper home page.
- Or open the Texas county directory and pick the county.
- Follow the official GIS link and search the site address or the property ID on the appraisal notice.
Rural Texas land often will not search by street address. The property ID or geographic ID on the tax statement is the reliable key. Platbookmapper links out to those county viewers. It does not host a zip-code map, and it does not replace a survey.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
