History
The North American Numbering Plan was created in 1947 to organise telephone numbers across the United States, Canada and neighbouring regions. When an area runs out of phone numbers, the North American Numbering Plan Administrator (NANPA) either splits the area or adds an overlay code that covers the same area; overlays are now the usual approach, which is why 10-digit dialing is standard in most places. Area code 509 serves Spokane, Yakima, Pasco.
How to dial 509
From the United States or Canada, dial 1 + 509 + the 7-digit number. From abroad, dial your international prefix, then 1 + 509 + the number — for example, +1 509 555 0132.
Is a call from 509 a scam?
Scammers can fake any area code, including 509. A number that looks local is not proof of who is calling. Never share passwords, verification codes or payment details with an unexpected caller; hang up and call the company back on a number from its official website. Report scam calls at reportfraud.ftc.gov, and forward spam texts to 7726.
