The Indiana Utility Regulatory Commission will accept public comments tonight at a meeting in Vincennes on what to do when available phone numbers run out for the 812 area code.
Available numbers are predicted to run out in 2015.
A new area code will need to be added either through an overlay or a geographic split.
The overlay method involves having more than one area code in a given area.
If a geographic split is used, all customers in part of the 812 area would keep their current numbers, while all customers in other parts of the 812 area would be required to switch to numbers with the new area code.
Tonight's hearing will be held at the Vincennes Lincoln High School Auditorium.
An informational session on the regulatory process and the options for area code relief will be held at 5:30 P.M.
Public comments will be accepted beginning at 6:00 P.M.
