The area code 843 is located in Charleston, South Carolina.
Area code 843 serves Charleston and much of coastal South Carolina, covering the Lowcountry and the Pee Dee regions along the Atlantic coast. It was introduced in 1998 after a split from 803, and it includes historic districts, major beaches, and busy port areas. This area code connects residents, businesses, and travelers across a region known for its rich history and coastal charm.
In 2015, overlay area code 854 was added to the same region, so new phone numbers may use 854, and 10‑digit dialing is required for local calls. Area code 843 spans the Eastern Time Zone (ET) and covers both urban hubs and barrier island communities. It includes key tourism, military, and port centers that drive the coastal economy.
The region blends American history with modern growth: Fort Sumter in Charleston Harbor is where the first shots of the Civil War were fired in 1861, while Myrtle Beach’s Grand Strand draws millions of visitors each year. The 843 service area also reaches parts of the federally recognized Gullah Geechee Cultural Heritage Corridor along the coast. If you see a call or text from 843, it likely ties to coastal South Carolina, including Charleston, Myrtle Beach, or Hilton Head.
