About Texas ZIP Codes — 2026 Guide
Texas ZIP codes were assigned by the U.S. Postal Service beginning in 1963. All Texas ZIP codes start with the digit 7, reflecting the state’s position in the national USPS zone system. The second and third digits identify the city or region, while the final two pinpoint the specific delivery area within that region.
Texas has over 1,900 active ZIP codes serving 30.5 million residents across 254 counties. Houston alone has more than 100 ZIP codes due to its enormous geographic footprint — at 669 square miles, Houston is the largest U.S. city by land area. Fast-growing cities like Frisco, Georgetown, and Leander have received new ZIP codes as their populations expanded.
ZIP+4 codes extend the five-digit base with four additional digits to pinpoint a specific building, floor, or street segment. These are used primarily by businesses and bulk mailers. For standard consumer purposes, the five-digit ZIP code is all that’s needed.
One common misconception is that ZIP codes match city or county boundaries. They do not — USPS ZIP codes follow mail carrier routes, not political lines. A single ZIP code can cross county or even city lines. For tax, legal, or government purposes, always verify the specific address rather than relying on ZIP codes alone.
