About the 843 region
843 covers Charleston in South Carolina, including Florence, Darlington, Horry, Marion and Dillon. The code has been in service since 1998.
As the Charleston region grew, 843 ran low on available numbers, so 854 was added as an overlay code over the same geographic area. Both codes are local to each other and 10-digit dialing applies throughout.
