This episode demystifies DEA numbers: who needs them, how they’re structured, and simple ways to verify them. Matt and Don walk through practitioner types, state-by-state prescribing nuances, the 2-letter/7-digit format, and the manual checksum formula—plus when to escalate concerns even if the number “checks out.” Part two of our six-part series on controlled substances.

Hosts:
Matt Uhrich & Don Weinberger

🎯 Learning Objectives:

• Identify which practitioners are allowed to write prescriptions for controlled substances.
• Explain the requirements for DEA numbers.
• Distinguish between a valid and invalid DEA number.

💊 Topics Covered:

• Who can prescribe controlled substances (physicians, dentists, vets, and mid‑level practitioners)
• DEA number format: two letters + seven digits; what the letters mean
• Manual and electronic DEA number verification; system limitations
• Red flags and when to involve the pharmacist
• State-level restrictions on what specific prescribers may write

🧠 Reflection Prompt:
If a controlled-substance prescription came in from a prescriber you don’t recognize, how would you verify the DEA number and what other red flags would you check?

📌 Key Takeaways:

• DEA numbers are required for Schedules II–V and follow a standard 9-character format.
• Use the checksum as a quick screen, but always escalate any concerns to the pharmacist.
• Pharmacy systems help but aren’t foolproof—licensure or scope limits may still block validity.
• Know your state’s rules for which practitioners can prescribe which schedules.
