Which data item is used by a Trusted Agent to lookup S-DEERS information?

• A. EDIPI/DOD ID number
• B. Social Security Number
• C. Token Serial Number
• D. Certificate Number

Answer: (A)

The data item used to look up S-DEERS information is the EDIPI, the DoD ID number. This unique identifier serves as the stable key that ties a service member to their records across DoD systems, allowing a Trusted Agent to retrieve eligibility and enrollment data from S-DEERS efficiently and securely. Using this DoD-issued ID preserves privacy by avoiding the use of sensitive details like a Social Security Number. The other options aren’t used for S-DEERS lookups: a Token Serial Number is tied to authentication hardware, not to personnel records; a Certificate Number relates to PKI certificates, not to DEERS eligibility data.
