S.C. Code Ann. § 33-56-45

A fire department conducting or intending to conduct a professional solicitation of charitable funds may comply with the registration and fee requirements of this chapter if the local governing body having jurisdiction over that department and other departments in its area singly registers the multiple departments annually and pays a single annual registration fee of fifty dollars pursuant to Section 33-56-30. The single annual registration and fee payment of fifty dollars effectively registers all fire departments within the jurisdiction of the local governing body. Recordkeeping is the responsibility of individual fire departments, and the Secretary of State shall provide all registered fire departments with the appropriate forms.
