Frogs and Toads of South Carolina and Georgia | SREL Herpetology

This site names the toads of South Carolina. It is certainly in the family Bufonidae, so there are four possible species. It will take sometime for you to come up with a proper conclusion, I can't tell from the pictures. You will have to research several factors including dorsal stripes, 'warts' per dark blotch, size of parotid gland etc.. Did you capture this toad or just leave it be? You may never know for sure from just the photos.
