Geographic Coverage & Major Cities
Area code 564 covers all of western Washington, from the Seattle-Tacoma metro to Olympia, Bellingham, and Vancouver. Because it is a regional overlay, it shares the identical footprint of the 206, 253, 360, and 425 codes rather than covering a separate zone.
- Seattle – the urban core shared with 206
- Tacoma & the South Sound – shared with 253
- Bellevue & the Eastside – shared with 425
- Olympia, Bellingham & Vancouver – outer western Washington, shared with 360
As a western Washington overlay, 564 numbers are assigned across the whole region alongside the four established codes.
A Brief History of Area Code 564
Area code 564 was activated in 2017 as an all-services overlay covering the entire western Washington region – the 206, 253, 360, and 425 areas all at once. Rather than overlaying a single code, it was designed as a broad regional relief code. An overlay adds a new code without changing existing numbers, which is why western Washington uses mandatory 10-digit dialing.
Time Zone & Best Time to Call
Numbers in the 564 area code use Pacific Time (PT). The region observes Daylight Saving Time, shifting from PST (UTC-8) to PDT (UTC-7) between March and November each year.
