An Electronic Data Interchange Personal Identifier
, or EDIPI
, is a unique number assigned to a record in the United States Department of Defense's Defense Enrollment and Eligibility Reporting System
(DEERS) database. A record in the DEERS database is a person plus personnel category (e.g. contractor, reservist, civilian, active duty, etc.). The Common Access Card
(CAC), which is issued by the Department of Defense through DEERS, has an EDIPI on the card. A person with more than one personnel category is issued a CAC for each role. Separating the identities is done so that revocation of one role’s permission can be accomplished simply by commandeering the card and/or revoking the digital certificates without affecting the other roles.
The EDIPI is a ten-digit number located in the barcode
on the front of the card, the barcode on the back of the card, and in the integrated circuit
chip embedded in the card itself. The first 9 digits are assigned unique numbers with the 10th digit being a check digit for the identifier.
The EDIPI can be used as a unique person identifier. It is unique to a person not to the person's role.
