Which inquiry method uses personal identifiers to confirm a subject's status?

The inquiry method that uses personal identifiers to confirm a subject's status is identified as CCH inquiries, or Criminal History Checks. This process involves accessing databases that include a person’s birth date, Social Security number, and other personal identifiers to retrieve detailed records about their criminal history, arrests, or convictions.

CCH inquiries are particularly valuable in law enforcement and legal contexts because they provide reliable, verified information about an individual. By cross-referencing personal identifiers, law enforcement can ensure that the information obtained pertains specifically to the individual in question, reducing the risk of misidentification.

Other methods like public records requests, background investigations, and witness statements may involve gathering information about a person, but they do not primarily focus on confirming status through personal identifiers in the same systematic and database-oriented manner as CCH inquiries do. Public records requests typically involve gathering documents or information that is publicly accessible, background investigations often include various sources like interviews and financial records but may not emphasize confirming identity through specific identifiers, and witness statements primarily rely on the recollections of individuals rather than systematic data checks.
