470 Area Code: Atlanta, Coca-Cola, Delta, and the World's Busiest Airport

Introduction

The 470 area code is a full overlay on Atlanta's 404 and 678 codes, covering the entire Atlanta metro — one of the most economically significant regions in the Southeast United States. Coca-Cola's global headquarters and Delta Air Lines' world hub at Hartsfield-Jackson, the world's busiest airport by passenger count, both sit in the 470 footprint. The overlay went into service in 2010 to relieve number exhaustion from Atlanta's rapid growth. Local numbers answer at 30–50% higher rates than out-of-state lines — Atlanta's logistics, media, healthcare, and technology sectors respond better to familiar Georgia area codes.

This guide covers the 470 overlay footprint, Atlanta's Fortune 500 anchors, Hartsfield-Jackson, the Georgia Tech and Emory research corridor, Eastern Time calling hours, and how to provision a 470 number with verified caller ID.

• Full overlay sharing 404, 678, and 770's geography across the Atlanta metro
• Home to Coca-Cola, Delta, Home Depot, UPS, and Hartsfield-Jackson Airport
• 10-digit dialing is mandatory for every call within the metro

Where 470 reaches and its overlay history

470 is a full overlay on the Atlanta metro — it shares the same geographic footprint as 404 (Atlanta proper), 678, and 770 (the suburban ring). Every community served by those three codes is equally served by 470.

• Atlanta city proper — Midtown, Buckhead, Downtown, and all Fulton County neighborhoods
• Decatur and DeKalb County — anchored by Emory University, the CDC campus, and Agnes Scott College
• Marietta and Cobb County — the aerospace and defense manufacturing corridor, including Lockheed Martin
• Gwinnett County — one of the fastest-growing, most diverse counties in the Southeast, anchored by Duluth and Lawrenceville
• Sandy Springs, Alpharetta, and Roswell — the north Fulton technology and corporate office corridor
• Smyrna, Kennesaw, and Acworth — Cobb County communities with healthcare, retail, and manufacturing jobs
• Clayton, Fayette, and Henry counties — the southern communities adjacent to Hartsfield-Jackson

Because 470 is an overlay, 10-digit dialing is mandatory for every call within the Atlanta metro — even calls between two 470 numbers, two 404 numbers, or any mix of the four codes sharing the same geography.

Georgia's original area code, 404, was assigned in 1947 to cover the entire state. Rapid growth prompted a full split in 1954, when 912 was carved out to serve South Georgia, leaving 404 for the Atlanta area alone. Suburban growth kept outpacing the numbering supply, so on August 1, 1995, the ring of suburbs — much of today's Cobb, Gwinnett, and north Fulton County — was assigned its own code, 770.

By 1998 the metro needed still more numbers, so on January 1, 1998, 678 launched as the region's first overlay, sharing the same geography as 404 and 770 rather than replacing either. On February 26, 2010, 470 went into service as a second overlay across that same footprint, making 10-digit dialing mandatory and giving Atlanta four area codes serving one contiguous market. The 770 guide covers the neighbouring ground.

Coca-Cola, Delta, Home Depot, and UPS: Atlanta's Fortune 500 economy

Coca-Cola and the global beverage giant

The Coca-Cola Company has operated from Atlanta since its founding in 1886, headquartered in Midtown within the 470 footprint. It employs thousands of corporate, marketing, legal, and supply chain staff, and the World of Coca-Cola museum draws over a million visitors a year.

Delta Air Lines and the aviation economy

Delta Air Lines is headquartered at Hartsfield-Jackson in College Park, employing tens of thousands of corporate, technical, and operations staff. Delta's Atlanta hub is the airline's largest global operation, anchoring an aviation services, maintenance, and logistics ecosystem across the southern and western metro.

Home Depot in Vinings and Cumberland

The Home Depot's global headquarters sits in Vinings, Cobb County, directing the world's largest home-improvement retailer with more than 2,350 stores across North America. The company employs thousands in technology, supply chain, merchandising, and corporate roles, with a significant data-analytics operation on its Atlanta campus.

UPS and the global logistics hub

UPS is headquartered in Sandy Springs, Fulton County, directing a global package-delivery operation from the 470 area code. The Sandy Springs campus houses global technology, finance, and executive functions, and UPS's Hartsfield-Jackson cargo presence makes Atlanta one of the most logistics-intensive metro markets in the country.

CNN and Atlanta's media industry

Ted Turner launched CNN from Atlanta on June 1, 1980, as the first 24-hour cable news network, and the network's headquarters has remained in the 470 footprint ever since. CNN's newsroom operations moved back to the original Techwood Campus in Midtown Atlanta in 2023 and 2024, closing out decades based at the downtown CNN Center. The network's presence anchored Atlanta as a national media production hub alongside Turner's other cable ventures, TBS and TNT, both still headquartered in the metro.

Tyler Perry Studios and Georgia's film industry

Tyler Perry Studios occupies 330 acres of the former Fort McPherson Army base within the 470 footprint — larger than the combined Warner Bros. and Paramount lots in Los Angeles — with 12 purpose-built soundstages and a backlot spanning a White House replica, a bank, and a jail. Perry opened the studio in 2019 as the first major film production studio outright owned by an African-American filmmaker, and productions there have included Black Panther and HBO's The Immortal Life of Henrietta Lacks.

Georgia's transferable film tax credit, worth up to 30% of qualified production spending, has helped the state build more soundstage space than New York and second only to California nationwide, with much of that production activity based inside the 470 metro.

Hartsfield-Jackson and the world's busiest aviation hub

Passenger hub and Southeast gateway

Hartsfield-Jackson carried more than 108 million passengers in 2024 — again the world's highest total, a title it has held nearly every year since 1998. As Delta's primary global hub, it connects the Southeast to every major market on every continent, making the metro a preferred location for companies needing strong international air access.

Cargo, logistics, and the airport economy

Hartsfield-Jackson handles significant air cargo operations feeding the 470 metro's logistics sector. The industrial corridor around Clayton County, College Park, Hapeville, and East Point hosts distribution centers, freight forwarders, and cargo handlers employing tens of thousands within the southern 470 footprint.

Georgia Tech, Emory, and the CDC knowledge corridor

Georgia Tech and the innovation ecosystem

Georgia Institute of Technology, in Midtown Atlanta, is one of the top engineering and technology universities in the country, feeding talent into Atlanta's aerospace, logistics-tech, fintech, and cybersecurity sectors. Its ATDC (Advanced Technology Development Center) is among the most active university-based tech incubators in the Southeast.

Emory University and the CDC public health cluster

Emory University in DeKalb County houses one of the top medical schools and health systems in the Southeast — Emory Healthcare is Georgia's largest health system. The CDC operates its global headquarters adjacent to Emory in Druid Hills, employing thousands of epidemiologists and public health scientists.

Time zone, getting a 470 number, and call trust

Time zone and calling hours for 470

The entire 470 area code observes Eastern Time — UTC-5 in winter (EST), UTC-4 during Daylight Saving (EDT). Atlanta shares the clock with New York and Washington D.C. — one hour ahead of Central, two ahead of Mountain, three ahead of Pacific. West Coast teams should plan outbound calls for early Pacific morning to reach the Atlanta business day before noon Eastern.

How to get a 470 number

1. 1Cloud phone platform — search available 470 numbers in real time and activate a line the same day. letsdial provisions an Atlanta number in under three minutes on a free trial.
2. 2Port your existing number — already have a 470, 404, 678, or 770 line elsewhere? letsdial ports it in without downtime and keeps the number active through the transition.

Call trust in a four-code overlay market

Atlanta's corporate market — Fortune 500 procurement at Coca-Cola, Delta, UPS, and Home Depot, plus pharma and biotech buyers at Emory and the CDC — applies aggressive call screening. Apply STIR/SHAKEN A-level attestation so every outbound 470 call arrives verified with your business name on screen. In a four-code overlay, recipients can't tell geography from the prefix, so verified identity matters more. Register text campaigns for 10DLC compliance and warm new numbers before scaling volume.

470 is officially documented under the North American Numbering Plan, which governs area code assignments across the US, Canada, and the Caribbean. That record is published in full as North American Numbering Plan.

Conclusion

The 470 area code gives access to Atlanta's full metro identity alongside 404, 678, and 770, reaching Coca-Cola, Delta Air Lines, Hartsfield-Jackson, and the broader corporate community that makes Atlanta the Southeast's commercial capital. A local Atlanta number is one of the most commercially valuable phone identities in the southeastern US, and letsdial provisions one in minutes with STIR/SHAKEN attestation and 10DLC registration handled automatically.
