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 OUCC's consumer fact sheet on the 317 area code, distributed at the field hearings, offers more details.
