To cancel a registration, a letter can be emailed to bdc@dph.sc.gov or faxed to 1-803-896-0627, Attention: Renewal Clerk, referencing your South Carolina Controlled Substance Registration number and Federal DEA number, stating that you are requesting to cancel your registration due to whatever the reason may be, e.g., moving out-of-state, retired, no longer practicing your profession, or you no longer possess a valid South Carolina practitioner license.

An expired registration that is canceled by BDC, without any correspondence from the registrant, due to failure to renew said registration by the registrant, cannot be reinstated unless a satisfactory explanation is provided, in writing, and a penalty of $100 is paid.
