N.C. Gen. Stat. § 55B-10

No professional corporation shall open, operate, or maintain an establishment for any of the purposes set forth in this Chapter without first having obtained a certificate of registration from the licensing board or boards. Applications for such registration shall be made to the licensing board or boards in writing and shall contain the name and address of the corporation and such other information as may be required by the licensing board or boards. If the board finds that no disciplinary action is pending before the board against any of the licensed incorporators, officers, directors, shareholders or employees of such corporation, and if it appears that such corporation will be conducted in compliance with the law and the regulations of the board, the board shall issue, upon the payment of a registration fee, not to exceed fifty dollars ($50.00), a certificate of registration which shall remain effective until January 1 following the date of such registration or until such other expiration or renewal date as may be established by law or by the regulations of the licensing board.
