Northern Indiana[edit]

Prior to January 2002, the entire northern part of Indiana was under the 219 area code. Population growth and increases in cell phone numbers resulted in the 219 region being split into 3 sections. After a random drawing, Northwest Indiana was allowed to retain the 219 area code.

Central Indiana[edit]

317 covered all of Northern and Central Indiana until 1948, when 219 was created. Central Indiana remained under the 317 banner until 1997 (and was overlaid by 463 in 2016), when growth in and around Indianapolis prompted the creation of 765.

Southern Indiana[edit]

  • When the first area codes were mapped out, southern Indiana was assigned 812 and has retained it ever since. The cities of Evansville, Vincennes, Terre Haute, Bloomington, Columbus, Madison and Jeffersonville are all included in the 812 area code.
  • The entire area served by 812 received an overlay code of 930 in 2014, with 10-digit dialing supposed to become mandatory throughout the area on September 6 of that year.[1] According to a recent Verizon alert this will now take effect on February 7, 2015.

Timeline for expansion and exhaustion[edit]

According to the Indiana Office of Utility Consumer Counselor, the 812 area code was set to run out of numbers by 2015. Following the 930 overlay, no additional relief should be necessary for the foreseeable future.

317 was set to run out of numbers in 2017, and as a result the 463 overlay was implemented. Likewise, after the 317/463 overlay, no additional relief should be necessary in Indianapolis for the foreseeable future.

The northern area codes are not expected to run out until well beyond 2040, and 765 should not run out of numbers until around 2030.[2]
