History of 564 Area Code
The 564 area code was introduced on August 28, 2017, to meet the growing demand for phone numbers in western Washington. It was first added as an overlay to the 360 area code, allowing new numbers to be assigned without changing existing ones. Because of this, 10-digit dialing became mandatory for all local calls in the region.
Historically, Washington was originally served by a single area code, 206, which was later split in 1957 to create 509 for eastern areas. As demand continued to rise, 360 was introduced in 1995 for western regions outside Seattle. Over time, 564 was expanded to overlay additional areas, including 206, ensuring enough numbering capacity for future growth.
