New Area Code for Indiana

Tuesday, May 19, 2015
On April 8, 2015 the Indiana Regulatory Commission (IURC) approved an all-services overlay as the relief method for the 317 NPA. The 317 NPA serves the central area of Indiana. The new 463 NPA will serve the same geographic area currently served by the existing 317 NPA. Because of the overlay relief method, ten digit dialing will be required for all calls in this area before central office codes can be assigned to the new NPA. Permissive ten-digit dialing begins March 19, 2016, and mandatory ten-digit dialing begins September 17, 2016. The earliest activate date for central office codes in the 461 NPA is October 17, 2016.
