SC Area Code Overlay

South Carolina 843/854 Area Code Overlay

 

What is an area code overlay?

An overlay is the addition of another area code to the same geographic area as an existing area code. You won’t have to change your existing area code or phone number, but it does require you to dial the area code and the 7-digit number for all calls. In South Carolina, the 854 area code is being added to the area served by the 843 area code.

 

Who will be affected?

Anyone who has a phone number with an 843 area code is affected, as well as anyone who receives a phone number from the 854 area code in the future. The 843 area code generally covers the eastern and coastal counties in the state of South Carolina serving communities such as:

  •   Beaufort
  •   Bluffton
  •   Charleston
  •   Florence
  •   Hilton Head Island
  •   Myrtle Beach

The 854 area code will cover the same geographic area as the 843 area code.

 

What will be the new dialing procedure for customers with an 843 or 854 area code?

The new 854 area code is being added to the geographic area served by the 843 area code. Because more than one area code will serve the same geographic area, if you have an 843 or 854 phone number, you will need to dial  or enter the area code for all calls including calls within the same area code. To complete local calls from a phone with an 843 or 854 area code, the new dialing procedure requires you to dial the area code + 7-digit phone number.

 

When will the South Carolina 843/854 area code dialing change begin?

Beginning March 14, 2015, if you have an 843 area code, you should start dialing the area code for all calls. There will be a grace period, so if you forget and dial just 7 digits during the grace period, your call will still be completed.

Beginning September 19, 2015, if you have an 843 area code, the new dialing procedure (all 10 digits) will be required for all calls. On or after this date, if you don’t use the new dialing procedure, your call won’t be completed and a recording will instruct you to hang up and dial again.

Beginning October 19, 2015, new telephone lines or services may be assigned numbers with the 854 area code. If you have an 854 area code, you must dial the area code + 7-digit phone number on all calls or the call won’t be completed.

 

Why is the South Carolina 843/854 area code overlay necessary?

The 854 area code is being added to the area served by the 843 area code to ensure a continuing supply of phone numbers. Because more than one area code will now serve the same geographic region, the area code + phone number must be used when dialing any phone number, including calls within the same area code.

 

Will the South Carolina 843/854 area code overlay affect my service?

No. The only change is dialing the area code for all calls. Your current area code and 7-digit phone number will not change. The price of a call, your plan and coverage area, and other rates and services won’t change because of the overlay. All local calls will remain local, even though the area code will be required to place a local call.
