Area code 864


Area code 864 is an area code in the U.S. state of South Carolina that covers Greenville, Spartanburg, Anderson and 12 surrounding counties in upstate South Carolina. It was split from area code 803 on December 3, 1995. Until then, South Carolina had been one of the most populated states served by just one area code.
Other cities in the 864 territory include Clemson, Gaffney, Greer and Mauldin.
With 803 overlaid with area code 839 in May 2020, 864 is the last area of South Carolina that has not been overlaid. As such, it is one of the few urbanized area codes where seven-digit dialing is still possible. Under the most recent projections, it will likely stay that way at least through 2029.
