Area code 913 serves the northeastern corner of Kansas, including cities such as Overland Park, Olathe, and Kansas City (KS side). Created in 1947, it is one of the state’s original area codes and now exclusively serves the Kansas side of the Kansas City metropolitan area. The region is known for suburban growth, corporate headquarters, and proximity to major interstates and rail lines. Seven-digit dialing is still permitted. Area code 913 is a major identifier for suburban Kansas, combining modern affluence with a Midwest work ethic.
