How to Get a 564 Phone Number
There are three ways to get a phone number with the 564 area code, each suited to a different need:
- Buy from a premium-number specialist. Companies that hold curated inventories of specific area codes can sell you a 564 number directly, often with a one-time fee and ownership transferred to you (no recurring carrier fees). This is the option for picking a specific memorable number, or for getting an area code that most carriers won’t let you request. Contact us about a 564 number.
- Sign up with a VoIP carrier. Voice-over-IP services (such as Google Voice, OpenPhone, Grasshopper, and many others) can typically provision a 564 number on request, especially for active overlay codes. You won’t usually get to pick the specific number, but you’ll get a working line in the area code. This is the cheapest option for anyone who doesn’t need a particular number.
- Port an existing 564 number. If you already have a 564 phone number with another carrier, you can transfer it (port it) to a new service provider while keeping the number. This works for landlines, cell phones, and VoIP services, though landlines outside of Washington sometimes can’t accept inbound ports of 564 numbers due to 911 routing rules.

Is the 564 area code still in use?
Yes. 564 is actively assigned to new phone lines in Western Washington, including metropolitan Seattle, the Puget Sound region, and western areas outside the urban core.
What is the difference between 564 and 206?
Today they share the same geographic territory in Washington. New phone lines in the area may be assigned either code. The two codes work identically for calling, billing, and service.
What is the parent area code of 564?
Area code 564 is an overlay of 360. Both codes serve the same region of Washington.
Can I get a 564 number if I don't live in Washington?
Yes. Phone numbers are no longer tied to a physical address. With VoIP service or a number broker, you can hold a 564 number from anywhere in the world. The number routes to whatever device or carrier you specify.
Is 564 a scam area code?
No. 564 is a legitimate, active area code for Western Washington, including metropolitan Seattle, the Puget Sound region, and western areas outside the urban core. Like any area code, scammers occasionally spoof 564 caller IDs, but the code itself is heavily used by real Washington businesses, government offices, and residents.
Why does area code 564 exist if Washington already had area codes like 206 and 360?
Area code 564 was created as an overlay to relieve number exhaustion. It was first proposed in 1999 to address shortages in the 360 area code, but implementation was delayed until August 28, 2017. Rather than splitting a geographic region — which would require residents to change their numbers — regulators chose an overlay, adding 564 on top of the existing 360 territory. In 2025, it was further extended to overlay the 206 region as well.
Does having a 564 number mean I am in a different part of Washington than a 206 or 360 number?
No. Area code 564 is an overlay, meaning it covers the same geographic territory as 206 and 360. A person in Seattle may have a 206 number or a 564 number depending on when their line was activated. The digits no longer indicate a different location — only which pool of numbers was available at the time of assignment.
Is ten-digit dialing required for 564 area code calls?
Yes. Ten-digit dialing (area code + seven-digit number) has been mandatory throughout Western Washington since July 29, 2017, for all local calls. This rule applies to all area codes in the region — 206, 253, 360, 425, and 564.
Will 564 eventually overlay area codes 253 and 425 as well?
Potentially. Per NANPA analysis, the 564 overlay complex may be extended to cover 253 (Tacoma) and 425 (Bellevue/Snohomish County) if and when those codes near exhaustion, following the same phased approach used for 360 in 2017 and 206 in 2025.
