Introduction
The 770 area code covers the northern suburbs of Atlanta — one of the fastest-growing metro regions in the United States. Introduced in 1995 as a split from the 404 prefix, it serves over 4.5 million people across 29 counties in North Georgia, from tech-focused Alpharetta to lakefront communities in Hall County.
This guide covers the geography, dialing rules, scam awareness, economic context, and the practical steps to get a 770 number for your business.

What Is the 770 Area Code?
Area codes are the three-digit regional prefixes that route calls through the North American Numbering Plan (NANP), the system managing telephone numbers across the US, Canada, and participating Caribbean nations since 1947. The 770 prefix was carved out of the original 404 code in 1995 as Atlanta's population and business activity expanded beyond what a single code could serve.
Today, 770 is part of an overlay system alongside 404, 678, and 470 — meaning multiple prefixes serve the same geographic area. Ten-digit dialing is mandatory in the region for all local calls. For businesses, a 770 number signals presence in one of Georgia's most commercially active zones.

Dialing Rules for the 770 Area Code
All local calls within the 770 overlay region require 10-digit dialing (770-XXX-XXXX). The overlay with 404, 678, and 470 means the area code must be included on every call, even to a number in the same town.
Calling from another US state: dial 1-770-XXX-XXXX. Long-distance charges may apply depending on your carrier plan, though most modern plans bundle them. International callers use their country's exit code, then 1, then 770-XXX-XXXX — from the UK that is 00-1-770-XXX-XXXX.
Staying Safe from 770 Area Code Scams
High-population metro codes attract scam activity. Robocalls and spoofed local numbers are common across Atlanta's suburbs, with callers impersonating utilities, government agencies, and tech support services to extract payments or personal data.
Protect yourself by registering on the National Do Not Call Registry, using call-blocking apps, and never sharing financial details with an unsolicited caller. Hang up and verify any organization through its official published number. Report incidents at reportfraud.ftc.gov — doing so helps track fraud patterns across the region.
The Economic Landscape of the 770 Region
The 770 area code anchors one of the South's most productive metro economies. Major employers include Lockheed Martin in Marietta, Home Depot's headquarters in Cobb County, and a dense concentration of technology companies in Alpharetta — Georgia's Technology City of the South. Logistics operations connected to Hartsfield-Jackson's supply chains run through Gwinnett County.
The region carries a median household income of approximately $68,000, an unemployment rate below 3.5%, and projected employment growth in AI, cybersecurity, and healthcare. For businesses, a local 770 number connects directly into this economic ecosystem, signaling community presence to both consumers and commercial partners.
