Area code 316 serves south-central Kansas, including the city of Wichita and its immediate suburbs. It was one of the original area codes assigned in 1947 and originally covered most of southern Kansas. As the region grew, area code 620 was split off in 2001, leaving 316 focused on the Wichita metro area. Wichita, known as the “Air Capital of the World,” is a major center for aviation manufacturing and innovation. Ten-digit dialing is not required locally. Area code 316 carries both historical significance and modern vitality, representing a city and region that blend Midwestern roots with industrial leadership.
