Area Code Overview
Area code 770 was established in 1995 as a split from the 404 code, taking over service for the rapidly expanding Atlanta metropolitan suburbs. It covers a large arc of counties surrounding Atlanta: Cobb County (Marietta, Smyrna, Kennesaw), Gwinnett County (Duluth, Lawrenceville, Buford, Norcross), Cherokee County (Canton), Forsyth County (Cumming), Henry County (McDonough), and portions of several other suburban counties. As growth continued, the 678 overlay was added in 1998 and the 470 overlay in 2014, both covering the same geography.
770 territory encompasses some of the fastest-growing counties in the United States. Gwinnett County, anchored by Lawrenceville and Duluth, has transformed into one of the most ethnically diverse counties in the South, with large Korean, Indian, Hispanic, and Vietnamese communities. Cobb County is home to the Atlanta Braves' Truist Park, a growing corporate corridor along I-75, and large master-planned communities. Forsyth County has among the highest median incomes in Georgia. Across the region, HOA-governed subdivisions are the dominant residential form, and Hartsfield-Jackson Atlanta International Airport serves the entire metro — including substantial traveler populations from the northern suburbs. This mix creates three distinct and locally specific fraud patterns.
Scam Patterns in 770
Georgia Medicaid and PeachCare for Kids Impersonation
Georgia's Medicaid program and PeachCare for Kids (Georgia's CHIP program) serve large enrolled populations throughout the suburban Atlanta counties covered by 770 — particularly in Gwinnett County, which has high enrollment relative to its size due to its diverse and partially lower-income immigrant and working-class communities. Scam texts impersonate the Georgia Department of Community Health (DCH), claiming the recipient's Medicaid or PeachCare coverage is pending termination due to a redetermination requirement, a missing document, or an eligibility discrepancy. Recipients are directed to click a link to upload documentation or confirm personal information. A related variant impersonates navigators or enrollment assisters, offering to re-enroll recipients for a "processing fee." These scams are particularly effective in the post-COVID period during which states were genuinely conducting Medicaid redeterminations. Georgia DCH does not request sensitive information via unsolicited text. Coverage status can be verified at gateway.ga.gov.
Gwinnett County and Cobb County HOA Assessment and Subdivision Fraud
The northern Atlanta suburbs are defined by massive HOA-governed master-planned communities — subdivisions in Gwinnett, Cobb, Cherokee, and Forsyth counties routinely have hundreds to thousands of homes under HOA governance, with monthly or annual assessment obligations and the authority to levy special assessments for capital improvements. Scam texts target 770 homeowners claiming that a special assessment has been levied against their property and that a past-due balance — if not paid immediately via a provided link — will result in a lien being placed on the home. A related variant impersonates HOA management companies (real third-party management firms like Associa or FirstService Residential do manage many of these communities, lending the impersonation additional plausibility) requesting updated payment information for automatic dues drafts. Any HOA communication demanding immediate payment via text link should be verified by calling the management company at a phone number found on your original HOA paperwork or the community's official website — not the number or link in the text.
Hartsfield-Jackson Airport Baggage, Flight Insurance, and Refund Fraud
Hartsfield-Jackson Atlanta International Airport (ATL) is the world's busiest airport by passenger count, and it serves as the primary airport for the 770 northern suburbs — with large portions of Cobb, Gwinnett, and Cherokee county residents flying regularly through ATL. Scam texts targeting 770 numbers impersonate Delta Air Lines (whose global hub is ATL) or generic airline customer service, offering refunds for cancelled or delayed flights that require personal and payment information to process, or claiming that a traveler's checked baggage has been located and requires a "redelivery fee" paid via link. A related variant impersonates travel insurance companies, reaching travelers who have purchased third-party trip insurance through platforms like Expedia or Travelport, claiming a claim has been pre-approved and requires bank information for payment. Delta does not process refunds through unsolicited texts; baggage claims are handled through the airline's official lost and found system. Verify any airline communication through the carrier's official app or website.
VoIP and Spoofing Risk Assessment
Risk Level: MOD
770 is a large, geographically broad code covering both established suburban communities with legacy landline infrastructure and rapidly growing areas with predominantly mobile-first populations. The moderate risk designation reflects the genuine mix of line types across 770 territory. The code is spoofed in targeted campaigns — particularly HOA fraud and Medicaid impersonation — where appearing as a local suburban Atlanta number increases response rates. The proximity of Hartsfield-Jackson and the dominance of Delta in the Atlanta market make airline-related fraud a persistent and specifically localized pattern.
What To Do If You Receive a Text From a 770 Number
- Do not click any link in a text claiming to be from Georgia DCH, an HOA management company, or an airline. Navigate to official websites directly using an address you find yourself.
- Look up the number at Who Sent That Text Message to check for prior reports and to identify whether the number is a VoIP line before responding.
- Verify Georgia Medicaid or PeachCare status at gateway.ga.gov. Verify HOA balance and assessment status by calling your management company at a number from your original HOA paperwork. See our guide on identifying spoofed text messages.
- Report the text by forwarding to 7726 (SPAM). File with the FTC at reportfraud.ftc.gov. Report Georgia Medicaid fraud to the Georgia Medicaid Fraud Control Unit at 404-651-9000. Report HOA-related fraud to the Georgia Attorney General's Consumer Protection Division at consumer.georgia.gov.
Frequently Asked Questions
What area code is 770?
Area code 770 covers the northern and outer Atlanta suburbs, including Cobb County (Marietta, Smyrna), Gwinnett County (Duluth, Lawrenceville), Cherokee County (Canton), Forsyth County (Cumming), and Henry County (McDonough). It was established in 1995 as a split from the 404 area code.
What is the difference between 770, 678, and 470?
All three area codes cover the same geographic territory — suburban Atlanta and the surrounding metro counties. 770 is the original suburban Atlanta code (1995); 678 is a 1998 overlay added when 770 numbers were exhausted; 470 is a 2014 overlay added for the same reason. Receiving a call or text from any of the three indicates a suburban Atlanta-area number, with 678 and 470 skewing more heavily toward mobile and VoIP lines.
Is Hartsfield-Jackson Airport in the 770 area code?
The airport itself (College Park, Georgia) is in the 404 area code. However, the vast majority of north Atlanta suburban travelers using ATL live in 770/678/470 territory, and scam texts targeting airline passengers in the northern suburbs specifically use 770 spoofed numbers to appear as local outreach from airline or travel insurance contacts.
