Frequently Asked Questions for Pharmacists on DEA Numbers beginning with "F"
Q: I have begun seeing DEA numbers that begin with the letter “F.” Are these numbers valid?
A: Yes. Due to the large Type A (Practitioner) registration population, the initial alpha letter “B” has been exhausted. DEA will begin using the new alpha letter “F” as the initial character for all new registration for Type A (Practitioner) registrations.
