Area code 509

Area code 509 serves Washington, including Spokane, Yakima and Kennewick (Pacific time). It has been in service since January 1, 1957.

Numbers starting with 509 drew 1,103 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 1,150 complaints to the FCC since November 2023. The number on your screen can be faked, so a 509 number proves nothing about where a call came from.

Phone companies holding 509 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 74% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
