The Complete 843 Area Code Guide: Charleston, South Carolina Coverage & Business Benefits

Introduction

The 843 area code covers coastal South Carolina's best-known towns — historic Charleston, sunny Myrtle Beach, and the resorts of Hilton Head Island. It split off from the old 803 code in 1995. Since then it has served eastern and coastal South Carolina, a region built on tourism, military bases, health care, and a fast-growing pool of professional firms. Charleston keeps landing on national best-city lists for business, so an 843 number now signals a real presence in one of the Southeast's most sought-after markets.

Understanding This Prefix and Its Geographic Relevance

Area code 843 is a geographic NANP code covering coastal and eastern South Carolina. The old 803 code once served the whole state, but coastal growth outran it. So in 1995, 843 took over the eastern half. No overlay has been needed since — the region's growth has stayed steady, not explosive. The 843 territory borders Georgia to the southwest. Businesses eyeing Augusta and northeastern Georgia can add 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, drawing corporate relocations, fintech startups, and long-standing manufacturers alongside its historic tourism trade. An 843 number plants a business firmly in this high-growth market.
• Tourism and hospitality reach — Myrtle Beach pulls in over 14 million visitors a year, and Hilton Head Island holds premium resort rates all year round. A local 843 number matters for hospitality operators, property managers, tour companies, and travel services.
• Military community connection — Beaufort County is home to Marine Corps Air Station Beaufort and Parris Island, while Joint Base Charleston serves the wider Charleston metro. Businesses that support military families and contractors gain a lot from a familiar local presence.
• Higher answer rates — South Carolinians are far more likely to pick up a call from an 843 number than from an unfamiliar out-of-state prefix. That is a real edge for sales, patient outreach, and customer service teams.
• Local SEO — an 843 number on Google Business Profile and in local directories lifts visibility in searches specific to Charleston, Myrtle Beach, and Hilton Head.

Companies that serve both the Charleston coast and the Upstate often pair an 843 line with a 864 area code to also cover Greenville and Spartanburg, giving them a presence across the whole state.

How to Get a Local Phone Number

• Step 1 — define your use case: Decide if the number is for a main business line, a vacation rental line, a health care practice, or a remote worker covering the Charleston market. That choice shapes which features you need, such as auto-attendant, call recording, or CRM routing.
• Step 2 — find a provider with 843 inventory: Pick a cloud provider that keeps a real-time list of available 843 numbers. Acepeak sets up South Carolina numbers instantly, with no physical presence required.
• Step 3 — choose your line type: A standard local number, a vanity number, or a DID for team routing. You can also port an existing 843 number if you are switching providers.
• Step 4 — activate and go live: Sign up, verify your identity, pick your number, and set up call routing. Most users are live within minutes. Porting from another carrier usually takes one to three business days.
