What data does the subscriber provide to lookup their S-DEERS information?

The subscriber provides their Department of Defense Identification (DOD ID) number to look up their S-DEERS information. The DOD ID is a unique identifier assigned to all individuals associated with the Department of Defense, including service members, dependents, and other eligible personnel. This number serves as a reliable means to authenticate and cross-reference an individual's records within the Defense Enrollment Eligibility Reporting System (DEERS).

Using the DOD ID ensures accuracy in retrieving the correct information from S-DEERS, as it is specifically designed to represent each individual in the system. In contrast, while elements such as Social Security Number, Employee ID, and Date of Birth may also be associated with a subscriber's identity, they do not provide the same level of specificity and reliability for accessing DEERS information as the DOD ID does.
