N.D. Cent. Code § 43-15-25
The license issued by the board to a pharmacist under this chapter, and the registration thereof, entitles the holder to act in the capacity therein stated for one year unless duly canceled, suspended, or revoked. Every licensee who desires to retain a license, on or before the first day of March in each year, shall pay to the secretary of the board a renewal fee in an amount to be fixed by the board not to exceed one hundred dollars. Upon payment of the fee, the board shall issue a renewal license. The license and renewal must be displayed in a conspicuous place in the pharmacy and drugstore where the holder is employed. After a licensee has held licenses duly issued over a period of fifty consecutive years, the secretary of the board may issue the licensee a lifetime license that entitles the licensee to act in the capacity of pharmacist thereafter without further payment unless the license is canceled, revoked, or suspended.
