726 area code — San Antonio, TX geographic
726 is the area code for San Antonio, Texas, in service since October 23, 2017, Central time. It is part of the 210/726 overlay complex — these codes share the same territory. Note that porting and VoIP mean a 726 number can be used from anywhere — the code marks where the number was assigned.
104 central-office prefixes are currently active in this code, spread across 30 code-holding carriers. Thousands-block pooling applies to 104 prefixes, so a single prefix can belong to several carriers. All numbers sit in one rate center.
Practical takeaway: the 726 label narrows geography to Texas, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.
Dialing: 10D locally, 10D to other codes.

FAQ
Why do 210 and 726 cover the same place?
They are overlays: when a code runs low on numbers, a new code is added over the same territory instead of splitting it. The 210/726 complex shares one service area, and local calls are dialed with 10 digits.
Will 726 run out of numbers?
NANPA's current forecast projects exhaust in 1Q 2072 — decades of capacity remain.
Why am I getting spam calls from 726 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 726 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 726 number from?
726 is assigned to San Antonio and surrounding areas of Texas in the Central time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
Is 726 a toll-free number?
No. 726 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
