Area codes 210 and 726 are telephone 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.
The original area code, 210, was created in an area code split from area code 512 in 1992. After only a few years, the threat of number exhaustion forced a split in 1997. Most of the 210 territory outside of Bexar County became area code 830, which completely surrounded 210. Area code 726 was assigned to the same numbering plan area in an overlay complex activated in 2017 to alleviate the threat of exhaustion of central office codes that was expected by 2018.
