About 564 Area Code
Area code 564 serves Seattle and the entire western Washington region as an overlay for existing codes 206, 253, 360 and 425. Introduced on August 28, 2017 to address telephone number exhaustion across the region, 564 covers major population centers including Seattle, Tacoma, Bellevue, Everett, Vancouver, Bellingham, Olympia and Bremerton. The code spans King, Pierce, Snohomish, Thurston, Whatcom, Kitsap, Skagit and other western Washington counties. It supports local voice and SMS-capable numbers used by businesses, tech companies, healthcare providers and service organizations across one of the nation's most dynamic economic regions.
Western Washington hosts major employers across technology (Amazon, Microsoft, Google), aerospace (Boeing, Blue Origin, SpaceX), healthcare, maritime and international trade. Local businesses use 564 numbers for customer support, sales calls, appointment scheduling, tech support and logistics coordination. These practical use-cases deliver higher answer rates than toll-free or out-of-area numbers because they signal local presence and community connection in this tech-savvy, globally connected market.

How Does Local 564 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 564 number in Seattle and Washington, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.
The typical parts of a United States local number are:
- Country code (+1): identifies United States for international routing.
- Area code (564): directs the call to the Seattle / Washington region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
Example formats:
| International Format (E.164) | +1 564 555 1234 |
| Local Format (National) | (564) 555-1234 |
