470 Area Code: Metro Atlanta Location, Coverage & Scam Check (2026)
The 470 area code covers all of metro Atlanta — 29 counties, 143 cities. Learn why you got a 470 number, how it differs from 404, scam alerts, and international calling tips.
Got a call from a 470 number? It's from metro Atlanta, Georgia — but unlike the iconic 404 area code (which only covers Atlanta's urban core), the 470 area code spans the entire metropolitan area. Covering 29 counties and 143 cities with over 6.4 million residents, 470 is what most new Atlanta-area phone numbers get assigned to today.
470 Area Code at a Glance
Location: Metro Atlanta, GA (ITP + OTP)
Counties: 29 counties across metro Atlanta
Time Zone: Eastern (UTC-5 / UTC-4 DST)
Population: ~6.4 million (metro area)
In Service: February 26, 2010
Type: Overlay on 404/770/678
Where Is the 470 Area Code?
The 470 area code covers the entire metro Atlanta region — everything from downtown Atlanta to the furthest suburbs. It's an overlay code, meaning it shares territory with all other Atlanta area codes rather than having its own geographic boundary.
This is what makes 470 different from 404 or 770: those codes are geographically defined (404 = inside I-285, 770 = outside I-285). A 470 number tells you someone is in metro Atlanta, but it doesn't reveal whether they live in Buckhead or Buford, Midtown or Marietta.
Key point: Two neighbors on the same street could have a 404 number and a 470 number. The area code depends on when the number was assigned, not where you live. Since 404, 770, and 678 are fully allocated, most new numbers since ~2015 are assigned 470 or 943.

470 vs 404 vs 770: What's the Difference?
Metro Atlanta's five area codes can be confusing. Here's the definitive breakdown:
| Code | Year | Type | New Numbers? |
|---|---|---|---|
| 404 | 1947 | Original | All prefixes allocated — no new numbers |
| 770 | 1995 | Split | All prefixes allocated — no new numbers |
| 678 | 1998 | 1st Overlay | All prefixes allocated — no new numbers |
| 470 | 2010 | 2nd Overlay | Active — new numbers assigned here |
| 943 | 2022 | 3rd Overlay | Active — newest numbers assigned here |
The bottom line: 404 is a status symbol (it signals "I've been in Atlanta a while" or "I'm intown"), 770 says "suburbs," and 470 just means "I got my number recently." All calls between them are local — no long-distance charges.
History: Why 470 Was Created (and Why It Took 9 Years)
The 470 area code has an unusual history — it was reserved in 2001 but didn't go live until 2010. Here's what happened:
Area code 470 reserved by the Georgia Public Service Commission as the second overlay for metro Atlanta
Implementation delayed for nearly 9 years — number pooling and recycling slowed depletion of 404, 770, and 678
470 goes into service on February 26th, becoming the 347th area code in North America and one of 8 new codes that year
470 becomes the default for most new phone numbers in metro Atlanta as 404, 770, and 678 prefixes run out
Area code 943 added as a third overlay — demand continues growing
The 9-year gap between reservation and activation is unusual. In the early 2000s, the telecom industry introduced number pooling — a technology that recycles unused phone numbers more efficiently. This slowed down number depletion enough to delay 470's launch by nearly a decade.
