A Tale of Two Codes: The History of 317 and 463

The 317 area code has a rich history, dating back to 1947. It was initially assigned to serve the entirety of Indianapolis, Indiana, and the surrounding areas. As the city and its suburbs grew, the demand for phone numbers outpaced the availability within the 317 area code.

To address this issue, the 463 area code was created in 2016 as an overlay area code. This means the 463 area code geographically overlaps with the 317 area code, serving the same region.
