843 Area Code: Charleston, SC — Myrtle Beach, Hilton Head & Full Guide

Introduction

The 843 area code is South Carolina's coastal telephone prefix — covering historic Charleston, the Grand Strand resort beaches, Hilton Head Island, and the broad agricultural communities of the Pee Dee region. Understanding the 843 area code matters whether you are tracking an unfamiliar call from the Lowcountry or looking to build a credible local presence in one of the Southeast's most dynamic tourism and real estate markets. This guide covers the code's full history, every major city in the 843 zone, Eastern Time calling windows, scam call protection, and how to get a local virtual number from anywhere in the world. South Carolina's coast is growing fast — and a local 843 number is the fastest way to earn trust in a market where locals still pick up for familiar numbers first.

What Is the 843 Area Code?

The 843 area code is a North American Numbering Plan (NANP) code assigned to the eastern half of South Carolina — a large region that stretches from the North Carolina border in the north to the Georgia border in the south, and from the Atlantic Ocean coastline inland to the Pee Dee and Lowcountry regions. This zone encompasses the most culturally and economically distinct parts of South Carolina, including the Charleston Lowcountry, the Grand Strand beach corridor, the Sea Islands, and the agricultural heartland of the Pee Dee.

What Geographic Area Does 843 Cover?

The 843 area code covers roughly 23 counties in eastern South Carolina. Key counties include Charleston County, Horry County (Myrtle Beach), Beaufort County (Hilton Head), Florence County, Georgetown County, Berkeley County, Dorchester County, Colleton County, and Jasper County, among others. The zone borders the 912 area code in coastal Georgia to the south and the 252 territory in eastern North Carolina to the north.

843 Area Code History: The 803 Split

South Carolina was assigned the 803 area code in 1954 under the original North American Numbering Plan, and a single code served the entire state for over four decades. As South Carolina's coastal communities grew rapidly through the 1970s and 1980s — driven by resort development at Hilton Head, the expansion of Myrtle Beach's tourism corridor, and Charleston's emergence as a major port and cultural destination — pressure on the 803 pool mounted steadily. By the 1990s, mobile phone adoption and business fax lines were exhausting available numbers faster than the single-code system could accommodate.

The 1998 Split That Created 843

In 1998, regulators split the eastern half of South Carolina from 803 and assigned the new 843 code to the coastal and Pee Dee region. Columbia and the state's inland Midlands kept 803, while the coast — already distinguished by its tourism economy, port commerce, and distinct Lowcountry identity — gained a code that matched its geographic and cultural boundaries. The split also introduced mandatory 10-digit dialing for calls within the 843 zone.

Cities and Communities in the 843 Area Code

The 843 area code covers a remarkably diverse stretch of South Carolina — from the antebellum architecture of downtown Charleston to the oceanfront high-rises of Myrtle Beach and the gated golf communities of Hilton Head Island. Here are the major cities and communities that define the 843 zone.

Charleston

Charleston is the largest city in the 843 region, with about 155,000 residents in the city proper and over 850,000 in the greater Charleston-North Charleston metro. It is one of the most historically significant cities in the United States — founded in 1670, a major Revolutionary War and Civil War site, and home to Fort Sumter National Monument where the Civil War began. Today, Charleston ranks among the most visited cities in the South, recognized for its Rainbow Row, cobblestone streets, James Beard award-winning restaurants, and Port of Charleston — one of the busiest and fastest-growing container ports on the East Coast.

Myrtle Beach and the Grand Strand

Myrtle Beach anchors the Grand Strand — a 60-mile arc of Atlantic coastline stretching from Little River to Pawleys Island that draws roughly 20 million visitors per year, making it one of the most visited coastal resort destinations in the United States. The city proper has about 35,000 permanent residents, but the tourism economy, golf courses (over 100 courses within 30 miles), and entertainment venues support far larger numbers during peak season. North Myrtle Beach and Conway — the Horry County seat — are also significant 843 communities.

Hilton Head Island, Florence, and Beyond

Hilton Head Island in Beaufort County is one of the East Coast's premier resort islands, known for its planned communities, championship golf courses, and the Harbour Town Golf Links. It draws over 2.5 million visitors annually. Florence — the largest city in the Pee Dee region — serves as a regional healthcare, retail, and transportation hub with roughly 38,000 residents. Beaufort, Georgetown, Summerville, and Bluffton round out a diverse community of 843 cities, each with distinct character — from Beaufort's antebellum homes to Summerville's rapidly growing suburban economy northeast of Charleston.

Time Zone and Calling Hours

The 843 area code operates entirely in the Eastern Time Zone, consistent with the rest of South Carolina and the US East Coast. Standard time (EST) runs UTC−5 from the first Sunday in November through the second Sunday in March. Daylight saving time (EDT) runs UTC−4 from the second Sunday in March through the first Sunday in November. The 843 zone aligns with New York, Atlanta, and Miami in every season.

Why Businesses Choose an 843 Number

A local 843 number signals to South Carolina coastal customers that your business understands their community. In a region where local relationships and trust are central to commerce — from luxury real estate in Kiawah Island to vacation rental bookings in Myrtle Beach — an unfamiliar national prefix consistently underperforms a recognizable 843 number in both answer rates and callback conversions.

• Tourism and hospitality — the Grand Strand's 20-million annual visitors generate enormous demand for local-feeling booking services, tour operators, shuttle companies, and destination wedding vendors who need a legitimate 843 caller ID
• Real estate and vacation rentals — the Charleston and Hilton Head luxury markets, along with the Myrtle Beach vacation rental corridor, consistently favor local-number agents and property managers over out-of-state competitors
• Port and logistics — the Port of Charleston handles over 2.7 million TEUs annually, making it one of the top ten container ports in the US; vendors and freight brokers serving port clients benefit from a credible local 843 number
• Healthcare and services — MUSC Health (Medical University of South Carolina), Roper St. Francis Healthcare, and the region's growing network of specialty providers set a local-number standard that healthcare vendors and suppliers follow
• Remote routing — forward your 843 calls to any device anywhere in the world, maintaining a Lowcountry presence without any geographic constraint on your team

843 Scam Calls: How to Stay Protected

The 843 area code is a fully legitimate South Carolina code used every day by hundreds of thousands of residents, businesses, hospitals, and government agencies across the coast. Like any NANP area code, it can be spoofed — a scammer can display an 843 number without any real connection to South Carolina. For the official explanation of caller ID spoofing and consumer rights, see the FCC guidelines.

Common 843 Scam Patterns

Neighbor spoofing — displaying a local 843 number to increase answer rates — is the most frequently reported scam tactic in the region. IRS impersonation calls, Social Security fraud, and extended vehicle warranty scams are common scripts across the 843 zone. During hurricane season, FEMA impersonation scams and fraudulent home repair contractors also spike across the coastal counties — targeting homeowners who have recently filed insurance claims.

How to Protect Yourself

• Never share Social Security numbers, insurance policy details, or bank information with an unsolicited 843 caller
• The IRS and FEMA will never demand immediate payment by gift card or wire transfer — hang up if a caller makes these demands
• Use a reverse-lookup service before returning any unfamiliar 843 number
• Register on the National Do Not Call Registry at donotcall.gov to reduce unsolicited telemarketing

The Full 843 Picture

The 843 area code is the defining telephone prefix for South Carolina's coast — carved out of 803 in 1998 to give the Lowcountry, Grand Strand, and Pee Dee their own identity and number capacity. It operates in Eastern Time, covers one of the most visited and fastest-growing coastal regions in the American South, and serves industries spanning luxury tourism, container port logistics, healthcare, and tech-sector growth in the Charleston metro. Whether you are tracing an unfamiliar coastal SC call or evaluating a market entry into Charleston or Myrtle Beach, the 843 zone is legitimate, active, and thriving.

The next step is clear — if South Carolina's coast is a market you want to reach, securing a virtual 843 phone number today removes every barrier between your business and the region's fast-growing customer base. Local 843 clients respond better to a familiar coastal prefix than to an out-of-state or toll-free number, and a virtual number activates in minutes at a fraction of the cost of a physical South Carolina presence. Take that step now and start building real relationships across the 843 zone from wherever you work.
