About the 210 area code

Since 1992, San Antonio, Texas has had its own area code, 210, which also reaches Leon Valley, Helotes, Alamo Heights, and Kirby. Central time applies throughout.

The code was formed by splitting territory away from 512. Its footprint was trimmed twice when 830 and 956 were spun off, and today 726 sits on top of it as an overlay, so every local call is a ten-digit call.

Dialing note: 210 is part of an overlay complex with 726, so local calls in this area are dialed with all ten digits.

Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 10/08/2026.
