Area code 559 serves California’s Central Valley, including Fresno, Clovis, Visalia, and Tulare. It was created in 1998 from a split with 209 to accommodate the expanding population and agricultural industry. The region is known for its farming productivity, with crops like grapes, almonds, and citrus dominating the economy. Fresno, as the largest city, anchors the area with education, healthcare, and government services. Ten-digit dialing is generally required. Area code 559 is a symbol of California’s agricultural core, representing resilience, multicultural communities, and the essential labor that fuels the state’s food supply.
