S.C. Code Ann. § 50-9-320

No resident or nonresident born after June 30, 1979, may obtain a hunting license in this State unless he first exhibits the certificate of completion he receives pursuant to Section 50-9-310 to the authorized hunting license agent from whom he desires to buy a license. A certificate of successful completion of a hunter's education program issued by other states or territories of the United States, Canadian provinces, or other nations is valid for purposes of this article if the department approves the course as comparable to the program required by this article. A license issued in violation of this section is invalid.
