History: Area code 478 was created in 2001 as part of a split of the old 912 territory to meet rising demand for new phone numbers in Georgia. “According to the North American Numbering Plan Administration (NANPA), area code 478 was introduced in 2001 following a split from 912.” This change placed Macon, Warner Robins, and nearby counties in a distinct central Georgia code, while 912 continued to serve the coastal region. Today, area code 478 is the standard local code for many Middle Georgia phone numbers and businesses.
