470 Area Code: Atlanta, Georgia

The 470 code is one of several area codes serving metropolitan Atlanta, layered over the broader Atlanta-region geography. Atlanta itself sits in the rolling Piedmont country of north Georgia, on a high ridge that helped determine the city's location as a railroad junction in the nineteenth century — the city's original name, Terminus, reflected exactly that. The 470 designation, part of the North American Numbering Plan, covers the same broad metropolitan footprint long served by the older 404 and 770, and has been filling with allocations as Atlanta's number demand has continued to grow.

Other Georgia cities — Albany, Columbus, Macon, and Sandy Springs among them — recur in the directory's records linked to 470 numbers. None of those are inside the 470 footprint. Their appearance reflects standard public-record dynamics across Georgia, with porting and address linkages routinely placing other-city names alongside 470 records. The directory currently documents 421 distinct prefixes within 470 in detail, a working subset of the prefix population the code carries.

Atlanta's home values run well above the US median, in line with broader Atlanta-metro pricing pressure. Median household income sits above the national reading, the city's median age skews a few years under the US figure, and population places Atlanta among the largest cities in the southeastern United States. The metropolitan area as a whole pulls steadily on populations from across the surrounding region, and the 470 footprint shares the city's broader demographic profile because the codes overlap.
