Area code 509 serves eastern Washington, including cities like Spokane, Yakima, Walla Walla, and Pullman. It was created in 1957 from a split with area code 206. The region is known for agriculture—especially apples, wine, and wheat—as well as for its growing education and healthcare sectors. Eastern Washington is more rural and politically distinct from the Seattle metro area, and 509 reflects this unique identity. Seven-digit dialing is still used locally. Area code 509 symbolizes the inland character of Washington State, emphasizing independence, natural beauty, and a strong connection to the land.
