CODIS National DNA Index System

The CODIS (Combined DNA Index System) National DNA Index System is a computerized database used by law enforcement agencies across the United States to share and compare DNA profiles from crime scenes, missing persons, and DNA samples from convicted offenders. By analyzing specific regions of DNA, CODIS helps identify suspects, link crime scenes, and solve cases more efficiently. It supports justice and public safety by leveraging genetic evidence to find connections that might otherwise be missed. Access is restricted to authorized personnel, ensuring privacy and proper use of sensitive genetic information.
