About 843 Area Code
Area code 843 serves Charleston and the southeastern coastal region of South Carolina, known as the Lowcountry. Created in March 1998 after splitting from 803, the area code covers major population centers including Charleston, Myrtle Beach, Hilton Head Island, Florence and North Charleston. It spans 19 counties across the Grand Strand, Lowcountry and Pee Dee regions. The code supports local voice and SMS numbers used by tourism businesses, healthcare providers, port operations and military installations throughout coastal and inland communities.
The 843 region features a tourism-driven economy that generated over $14 billion in economic impact recently, with Charleston alone attracting millions of visitors annually. The Port of Charleston serves as a major economic driver for logistics and shipping, while Myrtle Beach powers the hospitality sector with resort operations and golf courses. Businesses use 843 numbers for reservation confirmations, customer support, tour bookings and service coordination. Local numbers typically yield higher answer rates than toll-free alternatives because coastal residents and visitors recognize and trust the familiar regional prefix.
FoneSwift displays real-time 843 inventory with Voice, SMS and MMS capabilities on this page. Availability changes as numbers are purchased or released. Since 854 was added as an overlay in 2015, both codes serve the same geographic area. If your preferred 843 number is unavailable, equivalent 854 numbers reach the same customer base, or nearby codes like 803 (Columbia) or 864 (Greenville) can extend your South Carolina footprint.
For businesses targeting coastal South Carolina, display numbers in both local and international formats (e.g., (843) 555-1234 and +1 843 555 1234) on websites and marketing materials. Register messaging traffic if you plan SMS campaigns to comply with A2P regulations and carrier requirements. Number porting is supported when carriers allow geographic transfers. Tourism, hospitality and service businesses often maintain the same number for years to preserve guest recognition and booking continuity.
