770 as an Overlay of 404
Area code 770 is an overlay of area code 404, meaning the two codes share the exact same geographic territory in Atlanta suburbs — most of the metro area outside Interstate 285 (the Perimeter), spanning 29 counties in North Georgia. When 770 was activated in August 1, 1995, all existing 404 phone numbers stayed unchanged. New phone lines in the region may now be assigned either 404 or 770, and ten-digit dialing is required for all local calls. For the full history of the area, its cities, and what these codes mean culturally, see our page on area code 404.

Browse 770 Numbers →There are three ways to get a phone number with the 770 area code, each suited to a different need:
- Buy from a premium-number specialist. Companies that hold curated inventories of specific area codes can sell you a 770 number directly, often with a one-time fee and ownership transferred to you (no recurring carrier fees). This is the option for picking a specific memorable number, or for getting an area code that most carriers won’t let you request. Browse our 770 inventory.
- Sign up with a VoIP carrier. Voice-over-IP services (such as Google Voice, OpenPhone, Grasshopper, and many others) can typically provision a 770 number on request, especially for active overlay codes. You won’t usually get to pick the specific number, but you’ll get a working line in the area code. This is the cheapest option for anyone who doesn’t need a particular number.
- Port an existing 770 number. If you already have a 770 phone number with another carrier, you can transfer it (port it) to a new service provider while keeping the number. This works for landlines, cell phones, and VoIP services, though landlines outside of Georgia sometimes can’t accept inbound ports of 770 numbers due to 911 routing rules.
