What Time Zone Is 678 Area Code in the USA?
Area code 678 falls under the Eastern Time Zone (ET), which is observed by most counties in Georgia. Like many regions in the eastern United States, this area follows daylight saving time rules. From mid-March to early November, clocks are moved forward by one hour, potentially affecting calling schedules and business operations for both residents and organizations.
The Eastern Time Zone and its daylight saving procedures are confirmed by verified time zone guidelines maintained by the National Institute of Standards and Technology, ensuring consistency across interstate and international communications.
History of the 678 Area Code
Area code 678 was established in 1998 as part of an overlay plan designed to supplement the existing 404 and 770 area codes within the Atlanta region. Rapid population growth, economic development, and an expansion of telecommunications services led to an increased demand for new telephone numbers. The overlay method allowed existing subscribers to retain their current telephone numbers without necessitating a widespread geographic split. Instead, 678 was introduced to provide additional numbering resources to accommodate new lines.
Over the years:
- 1995: Area code 770 was created to handle suburban regions surrounding Atlanta, splitting off from 404.
- 1998: Area code 678 was overlaid on the areas served by 404 and 770 to handle the increasing number of newly assigned lines.
- Continued Growth: Key business sectors, including technology, finance, and logistics, contributed to the sustained demand for telephone numbers in the Atlanta metropolitan area.

According to U.S. Census data for Georgia, the broader metro area population exceeds five million inhabitants, with a significant portion assigned either 404, 770, or 678 area codes. Additionally, the strong presence of industries in tech, healthcare, manufacturing, and services has contributed to consistent demand for new telephone assignments.

Is the 678 Area Code Toll-Free?
Area code 678 functions as a standard geographic code covering parts of Atlanta and its surrounding regions. Unlike toll-free codes—such as 800, 888, 877, or 855—calls placed to numbers in the 678 area code typically incur standard charges based on the caller’s telephone plan and the type of call placed. No specialized regulations designate 678 as a toll-free line.
For callers who need toll-free services, the Federal Communications Commission (FCC) offers guidance on assigning and managing numbers beginning with toll-free prefixes. Additional details may be found by visiting the FCC Toll-Free Resource. Organizations or individuals seeking more information regarding toll-free dialing or local calling rules may also consult the FCC’s public reference center located at 45 L Street NE, Washington, DC 20554.
