About the 864 region
864 covers Greenville in South Carolina, including Upstate, Spartanburg, Anderson and Clemson. The code has been in service since 1995.
As the Greenville region grew, 864 ran low on available numbers, so 821 was added as an overlay code over the same geographic area. Both codes are local to each other and 10-digit dialing applies throughout.
