What Is NamUs?
The National Missing and Unidentified Persons System (NamUs) is a national clearinghouse and resource center for missing, unidentified, and unclaimed person cases across the United States.
NamUs helps investigators match missing persons with unidentified remains to resolve cases and bring resolution to families.
At any given time, up to 100,000 persons may be reported missing in the United States with as many as 600,000 reported annually. While many of these individuals are found alive and well, some become long-term missing persons. At the same time, federal, state and local medicolegal death investigators are constantly working to provide names to thousands of deceased persons nationwide. Over 11,000 sets of unidentified human remains were held in medical examiner and coroner offices throughout the U.S. according to the 2018 Census of Medical Examiners and Coroners.
NamUs was created to assist with identifying these decedents by allowing investigators to match to long-term missing person cases and by offering professionals free forensic services.
