History of the 803 area code

The 803 area code is one of the original North American area codes established in 1947. It originally covered the entire state of South Carolina.

As the state population grew, 803 was reduced through splits:

  • 1995 — 864 split off for upstate South Carolina (Greenville, Spartanburg)
  • 1998 — 843 split off for coastal South Carolina (Charleston, Myrtle Beach)
  • 2020 — 839 added as overlay for remaining 803 territory

Today, 803 and 839 serve the same geographic area centered on Columbia. New phone lines may be assigned either area code, and 10-digit dialing is required for all local calls. For regulatory details, visit the South Carolina Public Service Commission.
