509 

The Washington area code that encompasses the ENTIRE East side of the state. Notably, Spokane. Although it covers a comically large area which points out the lack of actual people, it straws its pride and strength from not being as fractured as 360.

A: Hey, what's your number?
B: 509-xxx-xxxx.
A: Man, you must be from Spokane or the Tri-Cities, right?
B: No, I'm from Clarkston.
A: What? Isn't that in Idaho or something?
