Find any 509- phone number in Washington

The 509 area code is part of the North American Numbering Plan (NANP) which is used to assign telephone numbers throughout much of the United States, Canada, and the Caribbean. The 509 area code is the telephone area code for the eastern Washington State, including Spokane, which is the largest city it serves. This area code was created in a split from the 206 area code in 1957. It is now one of the 29 area codes Washington State has altogether.

The NANP divides areas of the country by telephone area codes, commonly referred to as area codes. In addition to geographic region, area codes often represent a particular type of service, such as a long-distance or toll-free service. Many area codes are split to form new area codes as populations or phone needs increase, allowing for more phone numbers in the same area. The 509 area code is a geographically based area code, meaning that people in the area are assigned telephone numbers with the 509 area code. This is not to be confused with a special service area code, such as 800, 888, or 900 numbers.
