Indiana was assigned a single area code in 1947: 317, covering the entire state. The split came quickly — 219 was added in 1948 for northern Indiana and 812 the same year for the south, leaving 317 with the central region around Indianapolis.
For nearly five decades the three codes were enough. 765 split from 317 in 1997 for the Indianapolis donut (Lafayette, Muncie, Anderson, Kokomo) leaving 317 restricted to Marion County.
Northern Indiana split further in 2002: 260 carved off northeast Indiana (Fort Wayne) and 574 took north-central (South Bend, Elkhart, Goshen), leaving 219 confined to Gary and the Calumet region. Overlays followed: 930 (over 812, 2014) and 463 (over 317, 2016).
Indiana's relationship with time zones is the most complex in the US — most of the state observes Eastern Time, but Lake County and Porter County (NW Indiana around Gary) plus several counties near Evansville observe Central Time aligned with Chicago. This means an Indiana number's "local time" depends on the area code.
