In the aa/ddmmyy/nnnn/zz format of evidence labeling, what does the nnn denote?

• A. The year the evidence was taken
• B. The initials of the forensics analyst
• C. The sequence number for the parts of the same exhibit
• D. The sequential number of the exhibits seized

Answer: (D)

The four-digit segment is the running number assigned to exhibits seized in that case. As each new piece of evidence is collected, it receives the next sequential value, giving every item a unique reference within the case. This makes it easy to track and reference specific items in reports and in court. The date portion already records when the seizure happened, and the leading part identifies the agency, while the trailing part handles sub-categorization or case-specific labeling. Therefore, the four-digit field represents the sequential exhibit number.
