The 770 area code was split off from 404 in 1995 to handle the suburban sprawl outside I-285. Instead of covering downtown Atlanta, it wraps around the city, catching Cobb, Gwinnett, Cherokee, and Fayette counties on its way through the metro's commuter belt [1]. Since then, overlays 678, 470, and 943 have joined it, which is why every call in the region needs 10 digits, even to the shop down the street [1].
Metro Atlanta drives about two-thirds of Georgia's economy, and most of that engine lives inside the 770 footprint [2]. Between the corporate campuses in Sandy Springs, the logistics parks near Duluth, and the small storefronts lining Roswell Road, this is one of the busiest small-business corridors in the Southeast. A local number here signals you actually work in the neighborhood, not just service it from far away.
When a customer in Kennesaw sees a 770 number pop up, they answer. When they see an unfamiliar out-of-state code, they often don't. That single detail can change your pickup rate, and it's the reason plenty of Atlanta-area businesses run their sales and support lines on Tonet with a 770 number, whether the team sits in Marietta or works remotely from three time zones away.

Frequently Asked Questions
Can I still get a 770 number, or has the pool run out?
New 770 numbers can be scarce because it's the oldest overlay in the region, but they do come available. If none show up when you sign up, you can pick from 678, 470, or 943, which cover the exact same area.
Do I have to dial 10 digits when calling other 770 numbers?
Yes. Because 770 shares its geography with 678, 470, and 943, the FCC requires 10-digit dialing for all local calls in the region, even to a business on the same street [1].
Can I port my existing 770 number to Tonet?
Yes. If your business already has a 770 number with another carrier, we can port it over for free. Most ports finish in about a week, and your service keeps running the whole time.
How much does a 770 business number cost?
Plans start at $10 per user per month, billed daily with no contract. Additional phone numbers are $2.50 per month each, so you can add a separate line for sales or a second location without much fuss.
Does a 770 number work if my team is remote or out of state?
Absolutely. Your team can answer 770 calls from a laptop, desk phone, or the mobile app anywhere in the country. Customers in Atlanta still see a familiar local number when you call them back.
