Welcome to the NamUs Website

The National Missing and Unidentified Persons System (NamUs) is a national information clearinghouse and resource center for missing, unidentified, and unclaimed person cases across the United States. Watch the video introduction from Lucas Zarwell, Director, Office of Investigative and Forensic Services, NIJ to learn more.


Individuals go missing every year


Unidentified bodies are recovered each year

The Nation's Silent Mass Disaster

The sheer volume of missing and unidentified person cases poses one of the greatest challenges to agencies tasked with resolving these important cases.

Over 600,000 individuals go missing in the United States every year.[1] Fortunately, many missing children and adults are quickly found, alive and well. However, tens of thousands of individuals remain missing for more than one year – what many agencies consider “cold cases”.

It is estimated that 4,400 unidentified bodies are recovered each year, with approximately 1,000 of those bodies remaining unidentified after one year.[2]
