About the 210 region
210 covers San Antonio in Texas. The code has been in service since 1992.
As the San Antonio region grew, 210 ran low on available numbers, so 726 was added as an overlay code over the same geographic area. Both codes are local to each other and 10-digit dialing applies throughout.
Split of 512; 1997: split three ways to create 830 and 956; 2017: overlaid by 726.
