956 area code — Laredo, TX geographic

Data: NANPA public reports, current as of July 28, 2026.

Phone numbers beginning 956 are registered to the Laredo area of Texas (Central time zone). The code entered service on July 7, 1997. Because of number portability and VoIP, the area code tells you where the number was issued, not where the caller is right now.

NANPA lists 723 active NXX prefixes in 956, assigned to 45 carriers. 585 of those prefixes are pooled — shared between carriers in thousands-number blocks. The code spans 35 rate centers (billing localities).

To check where a specific 956 number was issued, look up its six-digit prefix; to check who is actually calling, ignore the display and verify through an official callback number — caller ID is assertable and routinely spoofed.

Its parent code is 210, which it left in 1997.

Official projections put exhaust at 2Q 2029 — relief planning typically starts years ahead. Relief planning (a future overlay or boundary change) is in progress.

The dialing plan is 7D for home-NPA local calls and 10D across codes.

Among Texas codes, 956 stands out as projected by NANPA to exhaust its numbering capacity by 2Q 2029.

FAQ

Is 956 a toll-free number?

No. 956 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.

Will 956 run out of numbers?

NANPA's current forecast projects exhaust in 2Q 2029, so a new overlay is likely to be planned.

Why am I getting spam calls from 956 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 956 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 956 number from?

956 is assigned to Laredo 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.
