Area codes and dialing in South Carolina
South Carolina's 6 area codes mix older geographic codes with newer overlays. The busiest metros — around Charleston, Columbia, Greenville — carry the most numbers and rely on overlays, which is why 10-digit dialing is required there. Quieter parts of the state may still use a single code. The original code in the South Carolina list is 803 (Columbia).
Whenever a South Carolina region runs low on numbers, a new overlay is added on top rather than splitting the map, so existing customers keep their numbers. See 10-digit dialing for what that means in practice, or the newest area codes for upcoming changes.
