Area code 478 is a telephone area code serving part of the state of Georgia, in the United States. It covers Macon and central Georgia (Warner Robins, Swainsboro, Wadley, Milledgeville, Hawkinsville, Eastman, Cochran, Dublin, Perry). It was formerly part of area code 912. The new area code, along with area code 229 (for Southwestern Georgia), became effective in 2001 in a 3-way split.

Prior to October 2021, area code 478 had telephone numbers assigned for the central office code 988. In 2020, 988 was designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which created a conflict for exchanges that permit seven-digit dialing. This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021.
