Indiana counties that in whole or in part use 812 and 930.

Area codes 812 and 930 serve the southern third of the state of Indiana. 812 is the main area code and 930 became an overlay area code when available phone numbers were becoming limited. The area is Evansville (812's largest city) and most of its suburbs, the northern suburbs of Louisville and the northwestern suburbs of Cincinnati. Other cities in the area code are Bedford, Bloomington, Columbus, Greensburg, Jasper, Princeton, Seymour, Terre Haute, and Vincennes.

812 is a number that was included in the list of original NANP area codes, introduced in 1947. Available phone numbers were sufficient with the areas growth and has never been overlaid or split. On July 31, 2013, it was announced that 812 would be overlaid with area code 930, the state's first overlay. The move came because the 812 supply was expected to exhaust in 2015; the supply of numbers is limited because portions of the Louisville and Cincinnati LATAs spill into the 812 territory, meaning numbers located in Louisville's 502, Cincinnati's 513 and northern Kentucky's 859 are not available for use.[1] On March 1, 2014, a six-month permissive dialing period began, during which it was possible to complete calls within the 812 area with both seven and ten digits. Ten-digit dialing was originally planned to become mandatory in September 2014 with the first 930 numbers to become available in October.[2][3] However in August, the Indiana Utility Regulatory Commission delayed the implementation of mandatory ten-digit dialing until February 7, 2015, and the assignments of the first 930 numbers until March 7 to provide law enforcement and emergency medical services more time to update their telecommunication equipment.[4][5][6]
