Understanding the 803 Area Code

It’s easiest to grasp this code when you think of Columbia and the surrounding Midlands.

• Location & Background
  Area code 803 was one of the original codes introduced in 1947, originally covering all of South Carolina.
  Over the years, growing population led to new codes: 864 in 1995 for the Upstate, and 843 in 1998 for the Lowcountry. In 2020, area code 839 was added as an overlay to 803, requiring ten-digit dialing throughout the region.

• Overlay & Dialing Impact
  The overlay with area code 839 means both codes now serve the same geographical area. Dialing across this region now requires ten digits—area code included—for all calls.

• Time Zone
  The entire 803 region operates under the Eastern Time Zone (GMT –5), including daylight saving time.

This reflects how overlays strike a balance—preventing number loss while nudging users to adapt.
