History of Area Code 678
The 678 area code was introduced in 1998 as an overlay to 404 to meet the growing demand for phone numbers in the Atlanta metropolitan area of Georgia. It covers cities such as Atlanta, Alpharetta, Marietta, and Sandy Springs and operates alongside area codes 404, 770, 470, and 943. As additional overlays were added over time, ten‑digit dialing became necessary, ensuring all calls connect correctly without requiring any existing numbers to change.
How Does a 678 Phone Number Work for Your Business?
A 678 phone number helps your business establish a local presence in the greater Atlanta metropolitan area without needing a dedicated physical office, in cities like Atlanta, Duluth, and Lawrenceville. It allows companies to connect with customers across north-central Georgia using landlines, mobile phones, or VoIP systems, while managing calls professionally from anywhere.
In the 678 overlay zone, local calls must be dialed using the full 10‑digit number (area code + phone number), while long‑distance calls within the U.S. require adding a leading 1 before the 10‑digit number (for example, 1‑678‑555‑XXXX). International callers reach local numbers by dialing their country’s exit code, followed by the U.S. country code 1 and the 678 number.
Major carriers operate in the 678 region, including BellSouth, US LEC, Sprint, and Verizon. Simultaneously, businesses can select local 678 numbers using VoIP and virtual phone services like Calilio, taking advantage of features such as auto-attendant, call forwarding, and IVR. This helps businesses maintain a strong local presence across Georgia’s primary metro hubs.
