Toll-Free Calling to Upstate SC

There are no long distance toll charges for calls from campus phones to most of the telephones in upstate South Carolina. Toll-free calling to Upstate SC is available on all faculty, staff, and resident student telephones that are part of the campus phone system.

The 4th, 5th, and 6th digits of a 10-digit telephone number make up the telephone exchange number. The University's telephone number is 864-656-3311, so it is in the 656 exchange. Calls to all telephone exchanges in the 864 area code except 513 and 936 will be toll-free. There will be charges for calls to those two exchanges near Clover, SC. Calls to six exchanges in the 828 area code near Columbus and Tryon, NC will also be toll-free. Those exchanges are 802, 817, 859, 863, 894, and 899.

You do not have to remember whether an exchange is toll-free or not when dialing a call. You should continue to dial calls to locations outside the regular Clemson toll-free area by dialing 9, then 1, then the 10-digit telephone number. If the exchange you are calling is toll-free, you will not be prompted for your authorization code and you will not be charged. If the exchange you are calling is NOT toll-free, you will be prompted for your authorization code and toll charges will apply.

"802, 817, 859, 863, 894, and 899" (Near Columbus and Tryon, NC).
