The Missouri Bureau of Narcotics and Dangerous Drugs (BNDD) requires all individuals and firms who prescribe and dispense controlled substances within the state to be registered with the department. 

Applications can be submitted online or mailed. Registrations are issued for one year. Registrants must re-apply yearly for a new registration. There is no renewal. BNDD certificates are not sent out by mail, but can be printed from the BNDD website. 

Only one mailed reminder will be sent to each clinic. However, every clinician in the clinic needs to apply for registration in order to dispense or handle controlled substances.
