The area code 854 is located in Charleston, South Carolina.
Area code 854 serves Charleston, South Carolina, and the surrounding Lowcountry along the Atlantic coast. It is an overlay to area code 843, created to add more phone numbers while keeping the same geographic coverage. Introduced in 2015, 854 uses the same boundaries as 843, covering historic Charleston and nearby coastal communities in the Eastern Time Zone. This region is known for Charleston Harbor, the meeting of the Ashley and Cooper Rivers, and landmarks like Fort Sumter and the Ravenel Bridge.
The 854/843 overlay spans much of coastal SC, including major cities and tourist hubs:
Expect strong ties to tourism, port activity, and history here. From the cobblestone streets of Charleston’s Historic District to the beaches of Myrtle Beach and Hilton Head, many popular destinations fall within the 854 area code. Key institutions and employers in the region also use 854 numbers as new lines come online.
With the overlay, 10-digit dialing is required for local calls across the region, and existing 843 numbers did not change when 854 launched. Both wireless and landline phone numbers can be assigned with 854, and local calling areas and rates stayed the same. For context, 843 was created in 1998 from 803, and 854 was added later to meet growing demand in coastal South Carolina. When calling from abroad, use the country code +1, then the area code (854 or 843) and the seven-digit number.
