What data does the subscriber provide to the Trusted Agent or Enhanced Trusted Agent for looking up S-DEERS information?

The correct choice, which is the DOD ID, is essential for looking up S-DEERS information because it serves as a unique identifier for individuals in the Department of Defense's DEERS (Defense Enrollment Eligibility Reporting System). The DOD ID is a critical piece of data that allows the Trusted Agent or Enhanced Trusted Agent to accurately confirm an individual's identity and access pertinent records within the system.

Using the DOD ID facilitates seamless integration and retrieval of personal information, ensuring that the specific data required for verification or support services can be accessed swiftly and securely. This process ultimately enhances the efficiency of verifying eligibility for benefits and services associated with military members and their dependents.

Other options, while potentially valid identifiers in different contexts, do not provide the same level of specificity or assurance regarding the individual's affiliation with the Department of Defense. Social Security Numbers, for example, are more general and are tied to a broader range of civil identification rather than military-specific data. Similarly, a Driver’s License Number may not necessarily correlate with military status or identification, nor does Military Rank provide the necessary information for making definitive connections to DEERS records.
