History

Originally, 317 covered the northern two-thirds of Indiana, while area code 812 served southern Indiana. In the first split of the area code system since its 1947 inception, northern Indiana received 219 the following year. Despite Indianapolis's rapid growth and increased number demand, no further changes were made to 317 until February 1, 1997, when most of central Indiana received 765, with the Indianapolis area retaining 317.[1] As a result, 317 is the only one of Indiana's six area codes that does not border another state.
