What information must a subscriber provide to the LRA to look up their S-DEERS information?

The information that a subscriber must provide to the Local Registration Authority (LRA) to look up their S-DEERS (Defense Enrollment Eligibility Reporting System) information is the EDIPI/DOD ID Number. The EDIPI, or Electronic Data Interchange Personal Identifier, is a unique identifier assigned to each individual by the Department of Defense and is essential for accurately linking individuals to their PKI credentials within the DEERS system.

Using the EDIPI/DOD ID Number ensures that the LRA can efficiently and accurately access the subscriber's specific record in the S-DEERS database. This is crucial because it prevents any potential errors or mix-ups that could arise from using other identifying information. The military uses the EDIPI as a consistent means of identifying service members, making it the most reliable and robust option for this purpose.

On the other hand, while other data such as social security numbers, military service numbers, or birthdates could potentially identify a subscriber, they do not provide the same level of unique identification as the EDIPI/DOD ID number. The use of these other forms of information could lead to complications, as they may not be as reliable in a database lookup context, where multiple records could exist with similar identifying information.
