Area codes 812 and 930

The numbering plan area (NPA) includes Evansville and most of its suburbs, the Indiana portions of the Louisville and Cincinnati metropolitan areas, and the cities of Bedford, Bloomington, Columbus, Greensburg, Jasper, Princeton, Seymour, Terre Haute, and Vincennes.

The NPA also serves a small section of Kentucky located adjacent to Evansville and north of the Ohio River whose most notable landmark is Ellis Park Race Course, a Thoroughbred horse racing track.

Despite the presence of Evansville, Terre Haute and Bloomington, southern Indiana is not as densely populated as the rest of the state.

By 2013, area code 812 was expected to exhaust its supply of central office prefixes in 2015.

[4][5] 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.
