When verifying a suspect's identity, which piece of information should be checked first?

• A. Date of birth.
• B. Height.
• C. The license or official identifying document.
• D. Hair color.

Answer: (C)

The most reliable starting point for confirming who a person is is the license or official identifying document. Government-issued IDs are designed specifically to prove identity and carry objective data such as a full legal name, date of birth, a photograph, and a unique document number. Checking this first gives you a solid, verifiable anchor you can compare against the person in front of you, and you can assess the document’s validity—whether it’s expired, damaged, or contains authentic security features. Relying on a physical description like height or hair color is less dependable as an initial check because those traits can be difficult to measure accurately in the moment, can change over time, or can be altered. Self-reported information like date of birth is also less trustworthy without a verifying document. Once the official ID is confirmed, you can corroborate other details as needed, but the document provides the strongest, most authoritative basis for identifying someone.
