Introduction
The 843 area code brings together coastal South Carolina's most recognizable communities — from the cobblestoned streets of historic Charleston to the sandy stretches of Myrtle Beach and the resort communities of Hilton Head Island. Split from the original 803 code in 1995, the 843 prefix now serves eastern and coastal South Carolina, a region powered by tourism, military installations, healthcare, and a fast-growing professional services sector. As Charleston rises on national lists of best-in-class business destinations, the 843 code has become a signal of presence in one of the Southeast's most desirable markets.
Key Takeaways
- Area code 843 covers coastal and eastern South Carolina — Charleston, Myrtle Beach, Hilton Head Island, Florence, Beaufort, Summerville, and Conway.
- It was split from area code 803 in 1995 as South Carolina's coastal counties outgrew the capacity of a single statewide prefix.
- The territory observes Eastern Time (EST/EDT), aligning with major East Coast markets.
- Key industries include tourism, military (MCAS Beaufort, JB Charleston), healthcare, real estate, and manufacturing.
- A local 843 number can be obtained through a cloud provider instantly — no South Carolina address required.
Understanding the 843 Area Code and Its Geographic Relevance
Area code 843 is a geographic NANP code assigned to coastal and eastern South Carolina. When the original 803 code — which had served all of South Carolina since the state's inclusion in the NANP — could no longer keep pace with coastal growth, 843 was established in 1995 to serve the eastern half of the state. No overlay has been required since, reflecting the region's steady but manageable population trajectory. The 843 territory borders Georgia to the southwest — businesses with ambitions in Augusta and northeastern Georgia can extend reach with a 706 area code just across the state line.

Benefits of an 843 Area Code for Businesses
- Charleston Market Access: Charleston is one of the fastest-growing metros in the Southeast — a hub for corporate relocations, fintech startups, and established manufacturing alongside its historic tourism economy. A 843 number immediately anchors a business in this high-growth market.
- Tourism & Hospitality Reach: Myrtle Beach draws over 14 million visitors annually, and Hilton Head Island commands premium resort rates year-round. A local 843 number is essential for hospitality operators, property managers, tour companies, and travel services.
- Military Community Connection: Beaufort County hosts Marine Corps Air Station Beaufort and Parris Island, while Joint Base Charleston serves the broader Charleston metro. Businesses supporting military families and contractors benefit significantly from a recognized local presence.
- Higher Answer Rates: South Carolinians are far more likely to answer calls from a 843 number than from an unfamiliar out-of-state prefix — a measurable advantage for sales, patient outreach, and customer service teams.
- Local SEO: A 843 number in Google Business Profile and local directories boosts visibility in Charleston, Myrtle Beach, and Hilton Head-specific searches.
Companies serving both the Charleston coast and the Upstate often pair an 843 line with an 864 area code to cover Greenville and Spartanburg as well, establishing statewide South Carolina presence.
