360 Area Code: Olympia, Vancouver & Western Washington

The 360 area code covers western Washington state — the large portion of the state outside the greater Seattle metro. Olympia (the state capital), Vancouver (on the Oregon border), Bellingham (near Canada), Port Angeles, Aberdeen, and over 120 smaller communities all use 360. Created on January 15, 1995, when the original 206 was split, 360 now has its own overlay — 564, active since 2021 — because western Washington has grown large enough to need more numbers.

This guide covers where 360 is, clears up the California confusion, walks through the history, gives you the exact time zone, and explains how 564 works alongside it.

Where is the 360 area code?

The 360 area code location is western Washington — everything west of the Cascades that isn't served by Seattle's 206, Tacoma's 253, or the Eastside's 425. The footprint spans 126 cities across 19 counties, running from the Oregon border in the south to the Canadian border in the north.

Major cities and communities inside the 360 area:

What 360 does not cover: Seattle (206), the Tacoma 253 area code, and Bellevue and Everett (425). Those three codes serve the dense Puget Sound metro; 360 wraps around them.

Is the 360 area code in California?

No — 360 is exclusively a Washington state area code, with no presence in California. The confusion surfaces regularly in search data, most likely because callers receive an unfamiliar 360 number and assume it might be from California without checking.

California uses its own separate set of codes. The Central Valley is served by codes such as 350 for Stockton and Modesto, and 559 and 357 for Fresno and Visalia. Southern California uses 213, 310, 323, and 818, among others. None of these are 360, and 360 has never been assigned to any California location.

If you receive a call from a 360 number, the line is registered in western Washington state.

How 360 was created

Washington state ran on a single area code — 206 — from 1947 until the 1990s. As Seattle expanded and mobile phones arrived, 206 was projected to run out of available numbers.

On January 15, 1995, regulators split the state: 206 was kept for Seattle and King County, and the new 360 took western Washington outside the metro. At the time, a middle digit other than 0 or 1 was unusual; 360 was among the first US area codes to use one, reflecting how fast the national number pool was being consumed.

Growth continued. By 2017, VoIP adoption and further population gains pushed 360 toward exhaustion. The 564 overlay was assigned on August 28, 2017 and began issuing new numbers in 2021. Existing 360 subscribers kept their numbers unchanged; new lines across the same western Washington footprint may now receive either 360 or 564. Ten-digit dialing — area code plus seven digits — is required on all calls within the area.

What time zone is the 360 area code?

The 360 area code time zone is Pacific Time (PT), the same clock as Seattle, Portland, Los Angeles, and San Francisco:

• Winter (standard time): Pacific Standard Time (PST), UTC −8
• Summer (daylight saving): Pacific Daylight Time (PDT), UTC −7

Washington observes Daylight Saving Time, switching on the second Sunday in March and reverting on the first Sunday in November. When calling a 360 number from another time zone, use these offsets: +3 hours from Eastern, +2 from Central, +1 from Mountain.

What western Washington is known for

The 360 region spans coast, farmland, and forests, anchoring industries that rarely overlap in a single area code:

• State government — Olympia is Washington's capital; public administration is the dominant employer across the south 360 region, from agencies to contractors to legislative services.
• Timber and ports — Southwest Washington (Longview, Aberdeen) has deep roots in lumber and paper milling. Longview's port on the Columbia River is among the most active break-bulk ports on the West Coast.
• Skagit Valley agriculture — The Mount Vernon and Burlington area produces a large share of the nation's tulip bulbs, alongside berries, potatoes, and certified seed crops.
• Military — Whidbey Island Naval Air Station (Island County) is one of the largest naval air installations on the West Coast, supporting thousands of military and civilian jobs in the 360 footprint.
• Outdoor tourism — The 360 area includes Olympic National Park (Port Angeles gateway), North Cascades access via Bellingham, and the San Juan Islands ferry network from Anacortes.

For state contractors, agricultural businesses, hospitality operators, and government-adjacent firms, a 360 number signals genuine western Washington presence. Contact us to see which Olympia, Vancouver, or Bellingham prefixes are available for your business.

Spam calls from 360 numbers

Because 360 is a well-known Washington state code, scammers spoof it to make robocalls appear local. Common schemes targeting the Pacific Northwest include fake utility disconnection notices, IRS impersonation calls, and package-delivery texts with suspicious links.

The FCC's STIR/SHAKEN call authentication framework requires carriers to verify caller ID, which is why many phones now show "Spam Risk" labels on suspected spoofed calls before you answer.

If a 360 call seems suspicious:

• Let it reach voicemail before returning it.
• Never share one-time codes, card details, or login credentials with an unexpected inbound caller.
• Enable your carrier's spam filter — most major US carriers offer one at no extra cost.
• Report persistent robocalls to the FCC or FTC.

Key takeaways

• 360 covers western Washington outside Seattle–Tacoma–Bellevue: Olympia, Vancouver, Bellingham, and 126 cities across 19 counties.
• It is a Washington state code with no California connection — all 360 numbers originate in western Washington.
• 360 was created on January 15, 1995, split from the original 206 (which stayed with Seattle).
• The 564 overlay was assigned in 2017 and active since 2021; ten-digit dialing is required on all calls.
• Time zone is Pacific (PT) — UTC −8 in winter, UTC −7 during Daylight Saving Time.
