626 area code — Alhambra, CA geographic

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

The 626 area code covers Alhambra, California, Pacific time zone, and dates back to June 14, 1997. Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.

The code currently holds 730 working prefixes, held by 37 different carriers. Of these, 509 are pooled prefixes shared by multiple carriers. Numbers are anchored to 10 rate centers — billing localities that fix where each prefix belongs.

The current NANPA exhaust forecast is 1Q 2030. Relief planning (a future overlay or boundary change) is in progress.

Local calls inside 626 are dialed 1+10D.

Among California codes, 626 stands out as projected by NANPA to exhaust its numbering capacity by 1Q 2030.

To check where a specific 626 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.

The code was carved out of 818 (1997).

FAQ

Why am I getting spam calls from 626 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 626 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 626 number from?

626 is assigned to Alhambra and surrounding areas of California in the Pacific time zone. The three digits after the area code (the prefix) narrow it down to a rate center.

Is 626 a toll-free number?

No. 626 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 626 run out of numbers?

NANPA's current forecast projects exhaust in 1Q 2030, so a new overlay is likely to be planned.
