678 area code — Atlanta Northeast, GA geographic

Data: NANPA public reports, current as of July 28, 2026.

If a call shows area code 678, the number was issued in the Atlanta Northeast area — a code active since 1998, on Eastern time. Together with 404, 470, 770, 943 it forms the 404/470/678/770/943 overlay. Because of number portability and VoIP, the area code tells you where the number was issued, not where the caller is right now.

NANPA lists 783 active NXX prefixes in 678, assigned to 27 carriers. 620 of those prefixes are pooled — shared between carriers in thousands-number blocks. The code spans 41 rate centers (billing localities).

Official projections put exhaust for the 470/678/770/943 complex at 1Q 2039.

Its parent code is 470, which it left in 1998. Later relief produced 470 (2010) from its territory.

The dialing plan is 10D for home-NPA local calls and 10D across codes.

Practical takeaway: the 678 label narrows geography to Georgia, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.
