The term registry number refers to which identifier?

• A. Date of establishment
• B. Prescription number
• C. DEA number
• D. Registration date

Answer: (C)

A registry number is the unique credential issued by the DEA to professionals who are authorized to prescribe or dispense controlled substances. This identifier ties the practitioner to federal registration and is used on records and prescriptions to show they’re legally permitted to handle controlled substances. It isn’t a date or timestamp like date of establishment or registration date, and it isn’t the number assigned to a specific prescription. A prescription number is about a single order, not the clinician’s authorization. So, the term registry number refers to the DEA number.
