To identify the location of an Washington phone number, you need to understand the North American Numbering Plan (NANP) structure that all Alabama numbers follow: +1 NPA NXX XXXX.
The area code (NPA) is your key to determining location. By matching the three-digit area code to Washington's regional assignments, you can identify which part of the state the phone number originates from. Each area code corresponds to specific cities and counties throughout Washington, making it possible to narrow down the caller's general location.
Here's a complete list of Washington area codes with major cities:
Area Codes | Cities |
---|---|
206/564 | Seattle, Shoreline, Burien |
253 | Tacoma, Federal Way, Kent |
360/564 | Vancouver, Bellingham, Marysville |
425 | Bellevue, Everett, Renton |
509 | Spokane, Yakima, Spokane Valley |

Washington has approximately 10.6 million active phone numbers. Cell phones make up the majority with 8.7 million users, while traditional landlines have dwindled to 445,000 connections statewide. Internet phone services account for about 1.4 million numbers.
This means that when you search a Washington phone number, it's most likely a cell phone. The shift away from landlines means newer phone numbers are typically harder to trace than older landline numbers that had more public information available.
