Area code 219 split into 219, 260, and 574

On January 15, 2002, area code 219 was split into three parts due to number exhaustion. Northwest Indiana retained 219, north-central Indiana received 574, and northeast Indiana was assigned area code 260. This change was part of a three-way split to relieve number exhaustion.

The permissive dialing period for area codes 574, 260, and 219 ended on this date, requiring callers to use the correct area code for calls within the affected regions.
