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, when growth in and around Indianapolis prompted the creation of 765.

Southern Indiana[edit]

Timeline for expansion and exhaustion[edit]

According to the Indiana Office of Utility Consumer Counselor, the 812 area code will run out of numbers by 2015. It will be overlaid with 930 in the near future, after which no additional relief should be necessary for the foreseeable future.

317 is expected to run out of numbers in 2017, by which time a split or (more likely) overlay would be required for that area as well. Relief planning is currently in the early stages.

The northern area codes are not expected to run out until well beyond 2040, and 765 should not run out of numbers until around 2025. [2]
