The 360 area code is an integral part of Washington State's telecommunications infrastructure, serving a large area in the western part of the state.

Establishment and Geographic Coverage: The 360 area code was created on January 15, 1995, as a split from the 206 area code. This division was implemented to address the increasing demand for telephone numbers in the region. The 360 area code covers a significant portion of western Washington, excluding the Seattle metropolitan area. It includes cities like Olympia (the state capital), Vancouver (near Portland, Oregon), and Bellingham, as well as the Olympic Peninsula and several islands in Puget Sound.

Economic and Cultural Importance: The area served by the 360 area code has a diverse economy, with significant contributions from government services, education, healthcare, and tourism. The region's natural beauty, including the Olympic National Park and various islands, makes it a popular destination for outdoor activities and tourism. The area is also known for its rich cultural heritage and artistic communities.

Introduction of Overlay Area Code and Ten-Digit Dialing: To address the need for more telephone numbers, the 564 area code was introduced as an overlay for the 360 area code in 2017. With this overlay, ten-digit dialing (area code + phone number) became mandatory for all local calls within the region. This change marked a significant shift in dialing practices and reflects the region's ongoing growth and technological development.

These facts about the 360 area code underscore its crucial role in supporting the dynamic telecommunications needs of western Washington. The area code, along with its overlay 564, ensures efficient connectivity for a region known for its economic diversity, natural beauty, and cultural richness.
