Area code 478

It covers Macon and central Georgia (Warner Robins, Swainsboro, Wadley, Milledgeville, Hawkinsville, Eastman, Cochran, Dublin, Perry).

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.
