Area code 564

Area code 564 at a glance

Area code 564 is a geographic area code in Washington, in service since August 28, 2017, according to the North American Numbering Plan Administrator (NANPA). It is an overlay: 564 and 206 and 360 cover the same territory, so neighbors on the same street can have different area codes. It is in the Pacific time zone. The places with the most assigned exchanges include Bremerton, Vancouver, Olympia, Longview, and Aberdeen. By population, its largest named places are Vancouver, Marysville, Olympia, Bremerton, and Longview.

How calls are dialed in 564

According to NANPA's dialing-plan data, local calls within 564 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number. NANPA's dialing-plan note for this code reads: "1+10-digit dialing permissible at service provider discretion"

Carriers with 564 numbers

21 carriers hold the 95 central office codes assigned in 564. T-mobile USA, INC. has the most, with 22 (23%). 95 of the codes (100%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. The code holder is not necessarily the carrier serving a given number today, since numbers can be ported between providers.

Rate centers and towns in 564

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 564 has codes in 32 rate centers. Rate center names in the file are abbreviations; where one matches a Census place, the table links to that city's local-number page.
