[edit] Northern Indiana
- The 219 area code covers the northwest part of the state, including the cities of Gary, Hammond, Merrillville, Valparaiso and Michigan City.
- The 574 area code covers north-central Indiana, and includes the cities of South Bend, North Judson and Warsaw.
- The 260 area code covers the northeast section of Indiana, including Fort Wayne and Angola.
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.
[edit] Central Indiana
- The 765 area code covers the entire central part of the state, with the exception of the Indianapolis Metro area.
- The 317 area code covers the Metro Indianapolis area. The counties covered by 317 are Boone County, Hancock County, Hamilton County, Hendricks County, Johnson County, Madison County, Morgan County and Shelby County.
317 covered all of Northern and Central Indiana until 1948, when 219 was created. Central Indiana remained under the 317 banner until 1997, when growth in and around Indianapolis prompted the creation of 765.
[edit] Southern Indiana
- 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 Clarksville are all included in the 812 area code.
[edit] Timeline for Expansion and Exhaustion
According to the Indiana Office of Utility Consumer Counselor, the 812 area code will run out of numbers by 2011. Expansion is planned, however no indication of when or what the new area code will be numbered has been given. 317 is expected to run out of numbers in 2013, while 765 will exhaust its numbers by 2014. The northern area codes are not expected to run out until 2027. [1]
