Area code 478

Where area code 478 is

NANPA lists 478 as an in-service geographic area code for Georgia, first put into service on August 1, 2000. It is not part of an overlay, so every number in its territory starts with 478. It is in the Eastern time zone. The places with the most assigned exchanges include Warner Robins, Dublin, Milledgeville, Sandersville, and Swainsboro. By population, its largest named places are Warner Robins, Perry, Milledgeville, Dublin, and Fort Valley.

Where 478 numbers are local

478 holds 7.1% of the 6,301 central office codes assigned in Georgia, the 8th most of the state's 10 codes. 45 Census places could be matched to rate centers with 478 exchanges; the most populous are Warner Robins (86,199), Perry (24,792), Milledgeville (16,664), and Dublin (16,233). Each place page lists the exact prefixes and carriers for that town.

Ten-digit and seven-digit dialing in 478

According to NANPA's dialing-plan data, local calls within 478 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number. NANPA's dialing-plan note for this code reads: "1+10 digit permissible at service provider discretion."

Who holds 478 exchanges

53 carriers hold the 445 central office codes assigned in 478. Bellsouth Telecomm INC d/b/a Southern Bell Tel & Tel has the most, with 69 (16%). 292 of the codes (66%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. The code holder is not necessarily the carrier serving a given number today, since numbers can be ported between providers.

Local calling areas in 478

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 478 has codes in 50 rate centers. Rate center names in the file are abbreviations; where one matches a Census place, the table links to that city's local-number page.

An area code has 800 possible central office codes that start with 2 through 9, a few of which are reserved (such as N11 service codes and 555). 445 are assigned in 478, 56% of 800. 110 were assigned in 2020 or later.
