Start the 10-Digit Dialing Now!


The bad (or more accurately slightly inconvenient) news is that those in the 317 area code are soon going to have to dial three more numbers. The very good news is that consumers are not required to change their existing numbers.

To ease the inconvenience, the Indiana Utility Regulatory Commission and the Indiana Office of Utility Consumer Counselor urge callers to start their 10-digit dialing practices now. The new process will become mandatory on September 17 of this year.

The new 463 area code will be implemented in an overlay with the existing 317 area code. A similar 812/930 overlay took place in Southern Indiana last year. The change is necessitated by the projected exhaustion of 317 number combinations later this year.

This IURC/OUCC release has all the details.
