History of Area Code 843

Area code 843 was created on September 19, 1998, in a split from area code 803. The split gave coastal and eastern South Carolina a separate area code as telephone demand grew. Charleston, Myrtle Beach, Florence, and other eastern South Carolina communities moved into 843 at that time.

Area code 854 now overlays area code 843. The South Carolina Public Service Commission approved the overlay in 2013, and area code 854 entered service on October 19, 2015. Because of the overlay, 10-digit dialing applies in the 843 region.
