Area code 770

770 is a telephone area code assigned to metropolitan Atlanta, Georgia and its suburbs and exurbs. Today, 770 is generally reserved for use outside Interstate 285, with 404 generally reserved for inside the Perimeter (I-285).

This area code also serves north Georgia and is an overlay with the 404 and 678 area codes.

Currently, cell phone subscribers in the region can choose from either the 404, 678, or 770 area code when signing up for service.

In shorthand, 770 is usually written by local residents as 7/phone-number
