The National Missing and Unidentified Persons System Law and Legal Definition

The National Missing and Unidentified Persons System (NamUs) is a clearinghouse for missing persons and unidentified decedent records. It serves as a national repository for information on missing persons and unidentified remains. This system was developed in January 2007 by the National Institute of Justice (NIJ) in partnership with the National Forensic Science Technology Center (NFSTC).

Data regarding missing persons can be entered in NamUs by law enforcement professionals, missing persons clearinghouses and the general public. Any person can access the NamUs system to search or track cases, print missing persons posters, find resources and even map out travel routes in an effort to locate a missing person. The system searches for potential matches between missing and unidentified cases. Potential matches are presented to law enforcement case managers for closer review.
