Numbering plan area 770 completely surrounds area code 404. The two plan areas are separated roughly by Interstate 285, known locally as the Perimeter. Generally, 770 includes most of the metro area outside the Perimeter, while 404 serves Atlanta itself and most suburbs inside the Perimeter; a few cities are split between the two codes.
Area code 770, along with 404, is overlaid by area codes 678, 470, and 943. Area code 943 entered service on March 15, 2022. The Atlanta area was the first city in the United States to have mandatory ten-digit dialing throughout its metro area, roughly coinciding with the 1996 Summer Olympics in Atlanta. This means callers in the metro Atlanta region must dial all ten digits (area code + seven-digit number) for all local calls.
Area code 770 is a general purpose code which was placed in service on August 1, 1995.
Our Georgia phone number lookup service will analyze the three-digit prefix of any 770 area code phone number and will show which telecommunications company and rate center it was initially assigned to. This prefix code data may help to determine the U.S. carrier, Georgia geographic region, and local calling area associated with the phone number.
Phone numbers follow the following structure under the North American Numbering Plan:
Understanding the area code can help you determine if a call is local to your area. However, keep in mind that due to mobile number portability and VoIP services, the caller may be anywhere in the United States, so it’s best to search for the most recent phone number details.
