Which identifiers are listed as required in the Unique Identifier (FABS) section?

• A. FBI, Alien, BOP number, SSN
• B. FBI, Passport, Alien, SSN
• C. Alien, BOP number only
• D. FBI, Alien only

Answer: (A)

The key idea is understanding which identifiers federal systems use to uniquely identify a person across records. In the Unique Identifier section, the required identifiers are the FBI number, the Alien registration number (A-number), the Bureau of Prisons (BOP) number, and the Social Security Number (SSN). Each of these is a government-issued, stable identifier tied to a specific agency’s records, making it reliable for linking data across different systems. Passport comes into play as a travel document, not a core internal identifier used for matching across federal databases, so it isn’t listed as required. That’s why the set including FBI, Alien, BOP number, and SSN best fits what the section specifies.
