Area codes 210 and 726

Common card · No. 355851

Area codes 210 and 726 are telephone overlay area codes in the North American Numbering Plan (NANP) for San Antonio and most of its innermost suburbs in Bexar County in the U.S. state of Texas. Area code 210 was created in an area code split of 512 in 1992. After only a few years, the threat of exhaustion of central office codes forced a split in 1997. Most of the 210 numbering plan area outside of Bexar County was renumbered with either area code 830 (which completely surrounded 210) or area code 956. Area code 726 was assigned to the same area in an overlay complex, activated in 2017 to alleviate exhaustion concerns in 2018.
