[edit] History

Originally, 317 covered the all of Northern and Central Indiana and area code 812 covered Southern Indiana. However, in the first split of the area code system since its inception, Northern Indiana split off as area code 219 in 1948. Eventually, population growth and increased number demand necessitated another split. Beginning on February 1, 1997, with mandatory dialing effective June 28, the greater Indianapolis area retained 317 and the remainder of Central Indiana split off into area code 765.^[1]
