Area code 821

Area code 821 serves South Carolina, including Greenwood, Laurens and Greenville (Eastern time). It has been in service since August 19, 2024 and shares its area with 864.

Numbers starting with 821 drew 30 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 10 complaints to the FCC since November 2023. The number on your screen can be faked, so an 821 number proves nothing about where a call came from.

Phone companies holding 821 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 100% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
