Area code 316 serves south-central Kansas, including the city of Wichita and surrounding communities like Derby, Haysville, and Andover. It was one of the original area codes established in 1947 and once covered most of southern Kansas. In 2001, area code 620 was created from a split to serve the more rural portions, while 316 was retained for Wichita and its suburbs. Wichita, Kansas’ largest city, anchors the region with a strong aerospace, manufacturing, and healthcare presence. The 316 code is widely recognized across the state and is a point of pride for residents. It continues to represent innovation and economic strength in Kansas.
