564 will be newest area code for Western Washington

OLYMPIA – Washington state is getting a new area code next year.

The Utilities and Transportation Commission on Thursday approved a plan to implement 564 as the newest area code in Western Washington. The code will be available in areas currently covered under area codes 360, 206, 253, and 425 as those numbers run out. The new area code will first be distributed to new numbers in the 360 area code in the fall of 2017.

The commission on Thursday also approved mandatory 10-digit dialing for all Western Washington area codes by late 2017.

A projection by the North American Numbering Plan Administrator has the 360 area code being out of numbers by early 2018.
