Which area codes overlay 678?

678 is part of an overlay complex with 404, 470, 770 and 943. An overlay puts more than one area code over the same geography instead of splitting the region in two, so existing numbers keep their code and new ones get the added code. Two neighbours on the same street can hold different area codes. That is why ten-digit dialling is required here: you cannot assume a local call shares your area code.
