Home » Recent » Travel » Where Is Area Code 564: Comprehensive Washington State Guide

Where is area code 564? It is in Western Washington, enveloping metropolitan areas like Seattle, and serves as a telephone overlay covering several existing codes, such as 360. Introduced on August 28, 2017, area code 564 helps manage the increasing demand for phone numbers fueled by the region's growth. Initially designed to alleviate shortages experienced by the 360 area code, 564 now extends its reach, including parts of area code 206 since mid-2023. As the newest addition among Washington's area codes, it supports a population thriving in notable cities like Vancouver, Everett, and Olympia.

This delay was primarily due to the gradual increase in phone number demand, driven by both population growth and the expansion of businesses in Western Washington.

Implementation and Dialing Procedures

The introduction of area code 564 required a significant shift in dialing habits for residents and businesses in Western Washington. Since July 29, 2017, ten-digit dialing has been mandatory within the region. This means that even local calls now require the area code to be dialed, streamlining the process and preventing number exhaustion.

Interestingly, calls within the 564 overlay region are not considered long-distance. This convenience means that callers do not need to prefix their calls with a '1' when dialing from a landline, maintaining the ease of local communication despite the new area code.

Future Expansion Plans

The Washington Utilities and Transportation Commission (WUTC) has been proactive in planning for future number allocations. As of June 15, 2023, area code 564 has expanded to include parts of the 206 area code, with full implementation expected by June 10, 2025. This move addresses the projected exhaustion of area code 206 by 2025, ensuring continued availability of phone numbers.

Looking ahead, other area codes such as 253 and 425 may also be integrated into the 564 overlay as they approach their own numbering limits. This strategic planning helps accommodate the region's ongoing growth and the evolving communication needs of its residents.
