6 area codes assigned to South Carolina · Eastern Time
2 of South Carolina's area codes share territory with another. Codes in the same row serve the same places, so either can reach a number there — and ten-digit dialling is required throughout.
The remaining 2 codes cover their own area: 821, 864.
South Carolina went from one area code in 1947 to 6 today. A split carves territory off its parent; an overlay sits on top of it, which is why newer codes need ten-digit dialling.
