History of 317 Area Code
The area code 317 was introduced in 1947 as one of the original 86 area codes under the North American Numbering Plan (NANP). It initially covered a large portion of northern and central Indiana, including Indianapolis. In 1948, the northern section was separated to create area code 219, leaving 317 to serve primarily central Indiana. Since then, 317 has remained the main area code for Indianapolis and nearby regions.
In 1997, another split occurred, forming area code 765 to serve areas outside the Indianapolis metropolitan region. This required some users to change their phone numbers from 317 to 765.
As demand for new phone numbers increased, an overlay code, 463, was introduced in 2016 to serve the same geographic region as 317. Along with the overlay, 10-digit dialing became mandatory for all local calls within the region. Today, Indiana has eight active area codes: 219, 260, 317, 463, 574, 765, 812, and 930.
