564 is the area code for Bremerton, Washington, in service since August 28, 2017, Pacific time. The same territory is also served by its overlay code (206/564 complex). Keep in mind the code identifies where the number was registered; the person calling may be elsewhere.
The code currently holds 92 working prefixes, held by 19 different carriers. Of these, 92 are pooled prefixes shared by multiple carriers. Numbers are anchored to 32 rate centers — billing localities that fix where each prefix belongs.
Practical takeaway: the 564 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.
Local calls inside 564 are dialed 10D; 1+10-digit dialing permissible at service provider discretion.
The current NANPA exhaust forecast for the 360/564 complex is 4Q 2057.
The code was carved out of 360 (2017).

FAQ
Is 564 a toll-free number?
No. 564 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
Why do 206 and 564 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 206/564 complex shares one service area, and local calls are dialed with 10 digits.
Will 564 run out of numbers?
NANPA's current forecast projects exhaust in 4Q 2057 — decades of capacity remain.
Why am I getting spam calls from 564 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 564 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 564 number from?
564 is assigned to Bremerton 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.
