In the DEA numbering system, which designation is associated with researchers?

• A. G prefix for researchers
• B. H prefix for researchers
• C. J prefix for researchers
• D. L prefix for researchers

Answer: (A)

In the DEA numbering system, the first letter designates the type of registrant. The G prefix is designated for researchers who handle controlled substances in a registered research setting. This distinction helps the DEA track and regulate how substances are used in research, separate from prescribing or manufacturing activities. The rest of the number is the unique identifier, with the second letter often reflecting the registrant’s name initial and the digits constituting the individual ID. Other prefixes correspond to different registration types, but the G prefix specifically indicates researchers.
