Area code 210

Area code 210 serves Texas, including San Antonio (Central time). It has been in service since November 1, 1992 and shares its area with 726.

Numbers starting with 210 drew 2,153 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 819 complaints to the FCC since November 2023. The number on your screen can be faked, so a 210 number proves nothing about where a call came from.

Phone companies holding 210 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 71% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
