The 854 area code is an overlay serving eastern and coastal South Carolina, including Charleston, Myrtle Beach, and Hilton Head Island. Introduced in 2015, it was layered directly on top of the established 843 area code to supply fresh phone numbers across the fast-growing Lowcountry and Grand Strand.
Quick Summary of the 854 Area Code
| Area Code | 854 |
| State | South Carolina (SC) |
| Region | Eastern & Coastal South Carolina (Charleston & Myrtle Beach) |
| Major Cities | Charleston, Myrtle Beach, North Charleston, Mount Pleasant, Florence, Hilton Head Island, Conway, Beaufort |
| Time Zone | Eastern Time (ET) – EST / EDT |
| Dialing Format | 10-digit dialing required |
Geographic Coverage
The 854 area code shares an identical footprint with 843, covering the entire South Carolina coast – Myrtle Beach and Conway on the Grand Strand, the Charleston metro including North Charleston and Mount Pleasant, Beaufort and Hilton Head Island near the Georgia line, and Florence in the inland Pee Dee. Because it is an overlay rather than a separate region, an 854 number and an 843 number can exist on the same street.
Time Zone
The 854 area code observes Eastern Time (ET). Clocks follow Eastern Standard Time (UTC−5) in winter and shift to Eastern Daylight Time (UTC−4) from mid-March through early November. All of South Carolina is on Eastern Time. From the West Coast, this region is three hours ahead of Pacific Time, so a 9:00 AM call in California reaches a 854 number at 12:00 PM local time.
Tip: Business hours across the 854 region generally run 9:00 AM to 5:00 PM Eastern Time, Monday through Friday.
How to Dial a 854 Number
Because area code 854 operates as part of an overlay, 10-digit dialing is mandatory for every local and long-distance call. You must dial the full 10-digit number (854 + the seven-digit line number) even when calling a neighbor across the street. For international callers, dial your country’s exit code, then +1 (the North American country code), then 854, followed by the seven-digit local number.
Scam Alerts for the 854 Area Code
Like every U.S. area code, 854 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Charleston, Myrtle Beach, North Charleston, Mount Pleasant, Florence, Hilton Head Island, Conway, Beaufort should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Threatening calls demanding immediate tax payment via gift cards or wire transfer. |
| Utility Shut-off | Impostors claiming to be Dominion Energy threatening to cut power unless you pay now. |
| Vacation Rental Scam | Fraudulent Myrtle Beach or Hilton Head rental listings that vanish after you pay a deposit. |
| Storm Repair Scam | Fake contractors demanding upfront payment for hurricane or storm damage repairs. |
If you receive a suspicious call from a 854 number, take these steps to protect yourself:
- Do not share personal information such as Social Security numbers, bank details, or passwords over the phone.
- Hang up and verify by calling the organization back using an official number from its website.
- Report the call to the FTC at reportfraud.ftc.gov and to the South Carolina Department of Consumer Affairs.
- Block the number and consider registering with the National Do Not Call Registry.
Red Flag: Legitimate agencies such as the IRS, Social Security Administration, or your local utility company (Dominion Energy or Duke Energy) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 854 caller making such a demand is a scammer.
History and Economy of the 854 Region
n
The 854 area code entered service in 2015 as an overlay for the entire 843 region. Overlays let regulators add a fresh supply of phone numbers to a crowded area without forcing existing customers to change their established numbers, so 854 covers precisely the same cities as 843. The regional economy is powered by the Port of Charleston, advanced manufacturing – Boeing’s 787 Dreamliner plant and Mercedes-Benz vans in North Charleston – and an enormous tourism industry centered on historic Charleston, the beaches of Myrtle Beach, and the resorts of Hilton Head. Because 854 is the newer of the two coastal codes, it appears most often on recently activated mobile numbers and new business lines.

Looking Up an 854 Number
n
To identify an 854 caller, use a reverse phone lookup or search the complete 10-digit number online. Because 854 is a newer code often used for mobile numbers, some callers may have a smaller public footprint, so never share personal or financial details with an unverified caller.
