Area code 317 is an area code for Indiana. It was one of the first area codes created in 1947. It initially covered the northern and central portion of Indiana, but after it was split by 219 in 1948 and 765 in 1997, it now covers the central portion of Indiana. It covers areas such as Indianapolis, its capital city, and counties such as Johnson, Hendricks, Boone, Madison, and Shelby. It was overlaid by 463 in 2016.[1]
