Area code 317

Area code 317


Area code 317 is a North American Numbering
Plan area code for central Indiana. It serves most of the Indianapolis metropolitan
area, including Indianapolis itself and Marion County and all or part of Boone, Hancock,
Hamilton, Hendricks, Johnson, Madison, Morgan, and Shelby counties. 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. As a result, 317 is the only one of Indiana’s
six area codes that does not border another state. The number pool for 317 is currently expected
to exhaust in 2017, by which time a split or an overlay may be necessary. An overlay of 317 has been recommended. See also
