Area code 678 vs 943
678 and 943 are overlay codes: they cover the same ground in Georgia, and a number in one is a local call to the other. 678 is the original, in service since 1998. 943 was added in 2022 because the first was filling up – that is what an overlay is for. Today 678 has 785 of 786 blocks assigned (99.9%) and 943 has 153 of 786 (19.5%), so a new number in the area now almost always comes from 943. In the 33 days to 30 October 2026, 678 drew 864 FTC complaints against 402 for 943 – 73rd and 249th of 422 ranked codes. Older codes are spoofed more because they look more established. Neither code is better or safer than the other. They are the same geography, the same carriers and the same dialing rules; the difference is only how long each has existed and how full it is.

Frequently asked
What is the difference between area codes 678 and 943?

Yes. Overlay areas use ten-digit dialing for local calls, including between the two codes. Seven digits reaches a recording.
Will a new number be 678 or 943?
Whichever has blocks left – currently 943, at 19.5% allocated against 99.9% for the other. Carriers draw from the code with free blocks, which is why the newer code spreads over time.
Is 678 or 943 more likely to be a spam call?
