# South Carolina Area Code 843
The 843 area code serves the coastal regions of South Carolina, including the Charleston metropolitan area, Beaufort, and surrounding communities. Established in 1997 through a split of the original 803 area code, the 843 area code covers approximately the eastern and southern portions of the state. This region encompasses both urban centers and rural areas along the Atlantic coast, serving a population of over 2 million residents. The area code is primarily associated with the historic city of Charleston, known for its cultural significance and growing business sector, making 843 a recognizable identifier for this dynamic region of South Carolina.
The North American Numbering Plan (NANP) is the standardized system that designates area codes like 843 throughout the United States, Canada, and other territories. Administered by the North American Numbering Plan Administration (NANPA), this system organizes telephone numbers into geographic regions, each identified by a three-digit area code followed by a seven-digit local number. Area codes are assigned based on population density, calling patterns, and anticipated growth needs within specific regions. When an area's demand for phone numbers exceeds available capacity, new area codes are created through splits, as occurred with 843 in South Carolina. This systematic approach ensures efficient telephone service delivery and helps maintain organized communication infrastructure across North America.
