564 area code
The 206 and 360 numbering regions in western Washington.
564 overlays both the Seattle 206 region and the broad western Washington 360 region. It does not identify one particular city, and it should not be assumed to cover every other western Washington code. Ask for the town when deciding whether a request is local to a Seattle, Olympia or Vancouver business.

Questions about 564
Can 564 be either Seattle or elsewhere in western Washington?
Yes. NANPA lists 564 with both 206 and 360. The prefix alone cannot distinguish Seattle from communities in the much larger 360 region.
Is a 564 call safe to answer?
The 564 prefix identifies a numbering region, not a caller's identity or trustworthiness. Verify an unexpected request by contacting the organization through a number you already know.
Can I get a 564 business number?
Search the available numbers in VeraDial. Inventory changes, so a 564 number is not guaranteed. You can also keep your current carrier number and forward voice calls to a VeraDial line; existing texts stay with your carrier.
