ZIP Codes in Texas
Texas's ZIP codes cover the second-largest state in the country by both population and land area, home to around 30 million residents spread across four genuinely massive metro areas - Houston, Dallas-Fort Worth, San Antonio, and Austin - alongside vast stretches of West Texas desert and the fertile farmland of the Panhandle and Rio Grande Valley.
How ZIP Codes Are Organized Across the State
Texas's ZIP codes fall within the 75000–79999 range under the USPS system, one of the widest ranges of any state given Texas's enormous size. Dallas and Fort Worth occupy the lower end around 752xx–761xx, Houston sits near 770xx, Austin, the state capital, carries codes closer to 787xx, and San Antonio occupies 782xx. West Texas, including El Paso, pushes toward the upper end around 799xx.
Texas's Major Metro Areas by Population
The chart below shows how population splits across Texas's four major metro areas, each large enough to rank among the biggest in the entire country on its own.
Houston's ZIP codes cover the country's energy capital, home to a massive petrochemical industry and the Texas Medical Center, one of the largest medical complexes in the world. Dallas-Fort Worth, further north, has grown into a major corporate relocation destination, drawing significant Fortune 500 headquarters moves in recent years. Austin, the state capital, has built a reputation as a major tech hub, sometimes called "Silicon Hills." For a broader comparison, our full US ZIP code directory shows how Texas's wide range fits alongside every other state.
San Antonio and South Texas
San Antonio, home to the Alamo and a strong military presence through several major bases, anchors South Texas and carries a distinctly bicultural character reflecting the region's deep ties to Mexico. Further south, the Rio Grande Valley near the border carries some of the strongest bilingual and cross-border economic ties found anywhere in the country, with ZIP codes here reflecting significant trade activity with New Mexico and Mexico.
West Texas and the Permian Basin
West Texas, around Midland and Odessa, sits atop the Permian Basin, one of the most productive oil and gas regions in the world, and this area has seen dramatic economic booms tied to drilling activity over the past two decades. El Paso, further west, sits right on the border with Mexico and New Mexico, forming one of the largest binational metro areas in North America alongside Ciudad Juárez.
Why ZIP Codes Matter Beyond Mail
In Texas, ZIP codes carry enormous weight across multiple major industries - the energy sector relies on ZIP-level data extensively for both the Gulf Coast petrochemical corridor around Houston and the Permian Basin drilling region in West Texas. Austin's tech companies use ZIP codes for talent recruitment and site selection. And with no state income tax continuing to draw corporate relocations and new residents, ZIP-level population and business growth data across all four major metro areas remains closely watched nationally.
Border Regions and Neighboring States
Texas shares borders with four US states and a long international border with Mexico. To the west, El Paso connects into New Mexico and Mexico simultaneously. To the north, the Panhandle borders Oklahoma and New Mexico. And to the east, the border with Louisiana blends into similar Gulf Coast petrochemical geography near the Sabine River.
