About Area Code 839
Area code 839 is a North American Numbering Plan (NANP) area code that has been in service since 2021. It is administered by NANPA on behalf of the FCC and serves the South Carolina region anchored on Columbia.
839 is an overlay code, which means it shares its geographic boundaries with one or more existing area codes (803). Overlays are created when a region exhausts the supply of phone numbers in its original area code. Within an overlay region, residents must dial all 10 digits even for local calls, because the same 7-digit number can exist under multiple area codes.
Mobile numbers in 839 are portable: a person who moved away from Columbia may still carry a 839 mobile number on their device. If you receive an unexpected call from a 839 number, run it through the reverse lookup tool above for the most accurate, free identification.
If you live or do business in South Carolina, you may also interact with neighbouring or overlay codes (803). See the related codes section below to explore the rest of South Carolina.
