The Indiana Utility Regulatory Commission has approved a new area code for Southern Indiana to address its dwindling number of available telephone numbers.
The IURC said Wednesday the new 930 area code will be an overlay inside the existing 812 area code. Customers seeking new land lines or wireless numbers in that area will get the new 930 area code.
IURC spokeswoman Danielle McGrath says telecommunications companies must submit plans within 45 days for how they’ll implement the change, which should be in place by late next summer.
The change will mean that residents in the existing 812 area code will need 10-digit dialing for all calls, regardless of whether they are local or long distance.
The 812 area code was created in 1947. It’s been unchanged since that time.
