Defense Central Index of Investigations

Overview
The Defense Central and Investigations Index (DCII) is the automated central repository that identifies investigations conducted by DOD investigative agencies and personnel security determinations made by DOD adjudicative authorities.

DCII is an unclassified system that is operated and maintained by the Defense Investigative Service. Access is limited to DOD and other federal agencies with adjudicative, investigative, and/or counterintelligence missions. Information contained in the DCII is protected by the Privacy Act of 1994.

The DCII database consists of an alphabetical index of names and titles of individuals that appear as subjects, cosubjects, victims, or cross-referenced incidental subjects in investigative documents maintained by DOD criminal, counterintelligence, fraud, and personnel security investigative activities. In addition, personnel security determinations are maintained, by subject, in DCII.
