Area Code 812 History:

01/01/1947
Area code 812 was put into service.

Area code 930 has been approved as an overlay of area code 812 by the Indiana Utility Regulatory Commission with an implementation date of October 06, 2014. Effective September 06, 2014 ten digit dialing in the 812 and 930 area codes will be mandatory.

Ten digit dialing (area code + seven digit number) is necessary in the 812/930 overlay because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
