The area code 726 is located in San Antonio, Texas.
Area code 726 serves the San Antonio, Texas metro as an overlay to long-standing area code 210, covering the same geographic area in and around Bexar County. It supports phones across central San Antonio and nearby suburbs, reaching major landmarks like The Alamo, the San Antonio River Walk, and the San Antonio Missions (a UNESCO World Heritage Site). The Public Utility Commission of Texas approved the overlay in 2016, and new 726 numbers began rolling out in 2017 to meet growing demand for phone numbers. The region sits in the Central Time Zone and is one of the fastest-growing metro areas in the United States.
Major cities and communities in the 210/726 service area include:
As an overlay, 726 does not change existing 210 numbers—it simply adds more numbering options for the same places, including hubs like Joint Base San Antonio (Fort Sam Houston, Lackland, and Randolph). Local calling uses 10-digit dialing throughout the overlay, and calls from outside the area use 1 + 726 (or 210) + the seven-digit number. San Antonio is the second-most populous city in Texas, anchoring a diverse economy shaped by military, healthcare, tourism, and tech. This makes 726 phone numbers common for new mobile lines, small businesses, and new residents across the metro.
“10-digit dialing is required for all local calls in the 210/726 overlay.” (North American Numbering Plan Administration)
Quick facts: 726 is a local Texas area code tied to San Antonio, introduced in 2017, and it works side-by-side with 210 to serve the same communities and landmarks without changing local boundaries.
