Okla. Admin. Code § 45:10-3-8
Whenever any license issued by the Commission shall become lost or destroyed before the expiration date thereof, the licensee to whom such license was issued shall immediately reprint the license and display said license as directed by 37A-2-154. If the licensee is unable to reprint the original license, they shall make written application to the Director for a duplicate license. Said application shall set forth all the facts and circumstances concerning the loss or destruction of such license and shall be sworn to by the person applying for such duplicate. Upon receipt of such application, the Director may cause an investigation to be made, and if satisfied that the application is made in good faith and is true and correct, shall issue a duplicate in lieu of the license that was lost or destroyed. Such duplicate license shall show on its face that it is a duplicate license.
