South Carolina (803) Area Code Overlay

To ensure a continuing supply of telephone numbers, the new 839 area code will be added to the area served by 803. This is known as an area code overlay. Get ready to change the way you dial your local calls!

You do not need to change your existing area code or telephone number.

New Dialing Procedure
  • When calling a number within your own 803 region, dial ten digits: 1 + (803) plus the 7-digit telephone number. (Note: The 1 is optional when calling from a cellular or mobile phone.)
  • You should begin using the new dialing procedure on October 26, 2019. Beginning April 25, 2020, you must use the new dialing procedures for all local calls. After this date, if you do not use the new dialing procedures, your calls will not complete and a recording will instruct you to hang up and dial again.
  • Starting May 26, 2020, new telephone lines or services may be assigned numbers using the new 839 area code. All calls made within and between area codes 803 and 839 must be placed using the ten-digit telephone number (803 or 839 plus the seven-digit telephone number).

Don't Forget
  • Reprogram any equipment that stores frequently called local numbers so that it dials all ten digits. This includes life safety systems or medical devices, PBXs, fax machines, dialup Internet modems, alarm and security systems or gates, speed dialers, mobile phones, call forwarding settings, voicemail services, and similar functions.
  • Update your website, stationery, advertising materials, bank checks, contact information, and your personal or pet ID tags to include the area code.
What Will Not Change
  • Your telephone number, including current area code.
  • The price of a call, coverage area, or other rates and services.
  • Whatever is considered a local call now will still be a local call.
  • Continue to dial 1 + area code + telephone number (eleven digits) for calls to area codes other than 803 and 839.
  • In an emergency simply dial 911.
  • If 211, 311, 411, 511, 611, 711 or 811 services are currently available in your community, no extra digits are needed.
