Area code 425 is a geographic code serving Bellevue, Washington in the Pacific time zone. It has been in service since April 27, 1997. Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.
The code currently holds 627 working prefixes, held by 33 different carriers. Of these, 405 are pooled prefixes shared by multiple carriers. Numbers are anchored to 14 rate centers — billing localities that fix where each prefix belongs.
The code was carved out of 206 (1997).
The current NANPA exhaust forecast is 1Q 2044.
Local calls inside 425 are dialed 10D; 1+10-digit dialing permissible at service provider discretion.
Practical takeaway: the 425 label narrows geography to Washington, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.

FAQ
Will 425 run out of numbers?
NANPA's current forecast projects exhaust in 1Q 2044 — decades of capacity remain.
Why am I getting spam calls from 425 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 425 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 425 number from?
425 is assigned to Bellevue and surrounding areas of Washington in the Pacific time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
