Locations for Area Code - 854

Area code 854 is an overlay of 843, covering coastal South Carolina including Charleston, Hilton Head, and Myrtle Beach. Introduced in 2020, it accommodates the growing telecommunications needs of the state’s booming Lowcountry region. Ten-digit dialing is required. Although newer, 854 is now widely used for mobile numbers and new business lines. It reflects the ongoing population growth and development in one of the South’s most desirable and historically significant coastal areas, complementing 843 while supporting the region’s modern infrastructure.
