DEA number

A DEA number (DEA Registration Number) is a number assigned to a health care provider (such as a medical practitioner, optometrist, pharmacist, dentist, or veterinarian) by the U.S. Drug Enforcement Administration allowing them to write prescriptions for controlled substances.

Though there is no legal basis for preventing use as a general prescriber identification number, for security reasons the DEA prefers that DEA registration numbers are only used for authenticating and tracking prescriptions for controlled substances. The agency prefers that the National Provider Identifier be used for general identification purposes.^[1]

Current format

A valid DEA number consists of:

2 letters, 6 numbers, and 1 check digit
The first letter is a code identifying the type of registrant (see below)
The second letter is the first letter of the registrant's last name, or "9" for registrants using a business address instead of name.
Of the seven digits that follow, the seventh digit is a "checksum" that is calculated similarly to the Luhn algorithm, with the following steps:
- Add together the first, third and fifth digits call this CALC_1,3,5
- Add together the second, fourth and sixth digits and multiply the sum by 2, call this CALC_2,4,6
- Add CALC_1,3,5 + CALC_2,4,6 call this CHECK
- The rightmost digit of CHECK (the digit in the ones place) is used as the check digit in the DEA number

Registrant type (first letter of DEA Number):

A – Deprecated (used by some older entities)
B – Hospital/Clinic
C – Practitioner
D – Teaching Institution
E – Manufacturer
F – Distributor
G – Researcher
H – Analytical Lab
J – Importer
K – Exporter
L – Reverse Distributor
M – Mid Level Practitioner
P – Narcotic Treatment Program
R – Narcotic Treatment Program
S – Narcotic Treatment Program
T – Narcotic Treatment Program
U – Narcotic Treatment Program
X – Suboxone/Subutex Prescribing Program

^[2]

For example, for a registrant using a business address instead of a name, the DEA number might look like "F91234567". In some cases, multiple people (possibly including interns or nurses) are prescribing under the supervision of a more senior prescriber. In this case, the supervised individual may be identified by affixing an ID string to the end of the supervisor's DEA number, after a dash, e.g. "F91234567-001AB".

Older format

Prior to October 1, 1985, DEA registration numbers for physicians, dentists, veterinarians, and other practitioners started with the letter A. New registration numbers issued to practitioners after that date begin with the letter B, F, or G. ^[3]^[4] The rest of the format was the same as the new style.
