843 area code: A thorough guide to South Carolina’s coastal calling region
The 843 area code is more than a number on a dial pad. It’s the telecommunications umbrella for a vibrant slice of South Carolina, spanning historic cities, sun‑kissed shores, and fast‑growing coastal towns. This guide unpacks the origins, the geography, practical dialing rules, and the practicalities of living with the 843 area code in the modern world, from business communications to personal safety and digital resilience.
What is the 843 area code?
The 843 area code is a distinct numerical region within the North American Numbering Plan (NANP) used to route telephone calls to a defined part of South Carolina. Created in the late 1990s, it emerged when the older central area code was split to accommodate growing demand for telephone numbers. Today, the 843 area code serves a broad coastal belt that includes Charleston, the Grand Strand, and surrounding communities, connecting residents, tourists and businesses with a reliable local numbering system.
Where is the 843 area code located?
Geographically, the 843 area code covers coastal and southern South Carolina. It spans from the Charleston metropolitan area in the south‑eastern portion of the state, along the Lowcountry and sea‑island regions, to the Grand Strand along the Atlantic shore and inland pockets such as the Pee Dee region. In practical terms, if you live or work in or visit Charleston, Mount Pleasant, North Charleston, Goose Creek, Summerville, Hilton Head Island, Bluffton, Beaufort, Georgetown, Myrtle Beach, Conway, or Florence, you are within the remit of the 843 area code.
Origins and history of the 843 area code
The creation of the 843 area code came as South Carolina’s population and business needs grew. In the late 1990s, the NANP introduced splits and overlays to prevent exhaustion of available numbers. The 843 area code split away from the older 803 region—once covering much of the state—to focus on the rapidly developing coast. This historic split helped ensure that residents and enterprises along the coast could obtain numbers without delay, while preserving the existing 803 numbers for other parts of South Carolina. Today, the 843 area code stands as a stable identifier for one of the state’s most dynamic regions.

Dialing rules and practical number formatting in the 843 area code
Understanding how to dial a number within the 843 area code is essential for smooth communication. Here are practical rules and tips to keep in mind:
- Ten-digit dialing is standard for most local calls: the area code plus the seven‑digit local number. In many situations you will dial 10 digits even for a call within the same area code.
- Domestic long distance calls typically require dialing the country’s access code (1 in North America) followed by the 10‑digit number. If you are unsure, your mobile or landline provider can confirm the exact format.
- When saving numbers in your contacts, consider including the area code to ensure that the number remains dialable in all situations, such as when you travel outside the 843 area code.
- Porting numbers between mobile and landline services is common within the NANP, meaning you can retain your 843 area code even if you switch providers.
For businesses, it’s a good practice to present both the local number and the region in marketing materials. A clearly displayed 843 area code helps locals and visitors identify the call’s location, fostering trust and recognisability.

Best practices to stay safe
- Never share sensitive information over the phone unless you have verified the caller’s identity through an official channel.
