The 317 telephone area code serving Indianapolis and most of its suburbs is low on available numbers and is projected to run out in 2017. Short-term solutions, implemented at the state level, have significantly extended the lifespan of 317 since it was last changed in 1996. However, the long-term solution will require the introduction of a new area code.

On July 10, 2014, the telecommunications industry formally asked the Indiana Utility Regulatory Commission (IURC) to add a new area code to the 317 area. This request is pending as IURC Cause No. 44513.

The IURC will consider and determine when and how a new area code will be implemented for the 317 area. Testimony from the Indiana Office of Utility Consumer Counselor (OUCC) is due on January 6, 2015.

In its formal petition, the telecommunications industry seeks an overlay for the entire 317 area. All new area codes introduced in the United States since 2008 have used the overlay method, including the 930 area code that will be introduced in southern, south-central and western Indiana this fall. 

If an overlay is approved, changes to calling patterns will likely be phased in during 2015. With an overlay:

  • All existing 317 numbers would remain unchanged.
  • All customers would dial ten digits for local calls (area code + number), though local calling areas would not change. Calls that are currently local would remain local.
  • Toll calls would still use eleven digits (1 + area code + number).
  • Businesses, not-for-profit organizations, government agencies and other customers would not need to incur costs for reprinting signage, stationery, advertising, or business cards because of the area code change.

Consumers may provide input for the case record by submitting written comments to the OUCC through December 29, 2014. The IURC has held five public field hearings in the case:

  • Indianapolis - Friday, September 26, 10:00 a.m.: Room 222, PNC Center, 101 W. Washington St.
