Where Is Area Code 210?
Area code 210 serves San Antonio and most of Bexar County in south-central Texas. It covers the urban core of the San Antonio metropolitan area and many nearby communities.
The service area includes cities such as Alamo Heights, Castle Hills, Converse, Helotes, Live Oak, Schertz, and Universal City. Area code boundaries follow telephone exchanges rather than exact city or county lines, so 210 also reaches parts of nearby counties.
Notable features in the region include the San Antonio River Walk, the Alamo, and San Antonio Missions National Historical Park. The Texas Hill Country begins north and west of San Antonio, near the outer parts of the region.

History of Area Code 210
Area code 210 was established in 1992 after a split from area code 512. The original 210 service area covered a much larger part of South Texas than it covers today.
Area code 830 was created in 1997 from part of the original 210 region. Area code 956 was also created in 1997 from portions of area codes 210 and 512. These changes moved many communities outside the San Antonio area into new codes and left 210 centered on San Antonio and Bexar County. Area code 726 now overlays 210 in the same geographic region, so local calls require 10-digit dialing.
