 A new upstate area code goes into effect next week. South Carolina Public Service Commission is reminding residents the new 821 area code will go into effect on July 19th. It covers Greenville, Spartanburg, Anderson, and surrounding areas. Officials say this means people will have to use 10-digit phone numbers to make any calls in the region. Calls to 7-digit phone numbers will not go through. Existing phone numbers with the 864 area code will not change. I'm Thomas Cage.
