In apprehension and detention of aliens, obtain a different FDIN number for each drug.

• A. A single FDIN number for all drugs
• B. A different FDIN number for each drug
• C. No FDIN required
• D. FDIN assigned by case type

Answer: (B)

Each distinct drug you encounter must be documented with its own FDIN so the substance is uniquely identified in the record. The FDIN serves as a separate identifier for that particular drug, which keeps inventory, lab submissions, and chain-of-custody clear and traceable. Using a single FDIN for all drugs would blur which item is which, creating confusion in reports, evidence handling, and eventual disposition. FDINs aren’t assigned by case type; they are assigned per drug substance, with a new number for each different drug.
