N.C. Gen. Stat. § 25A-24

With respect to consumer credit sales, each instrument of indebtedness shall be identified on the face of the instrument as a consumer credit document, or otherwise clearly indicate on its face that it arises out of a consumer credit sale, provided, that such designation of an instrument of indebtedness regarding as sale which is not by definition a "consumer credit sale," shall not solely because of such designation cause the transaction to be a consumer credit sale.
