817 area code — Arlington, TX geographic
Area code 817 is a geographic code serving Arlington, Texas in the Central time zone. It has been in service since January 1, 1953. The same territory is also served by its overlay code (682/817 complex). Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.
The code currently holds 780 working prefixes, held by 34 different carriers. Of these, 466 are pooled prefixes shared by multiple carriers. Numbers are anchored to 25 rate centers — billing localities that fix where each prefix belongs.
As demand grew it in turn gave rise to 254 (1997), 940 (1997), 682 (2000).
The current NANPA exhaust forecast for the 682/817 complex is 2Q 2041.
Local calls inside 817 are dialed 10D.
To check where a specific 817 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.

FAQ
Why do 682 and 817 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 682/817 complex shares one service area, and local calls are dialed with 10 digits.
Will 817 run out of numbers?
NANPA's current forecast projects exhaust in 2Q 2041 — decades of capacity remain.
Why am I getting spam calls from 817 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 817 number does not prove the call originated there — see our guide to spotting spoofed calls.
