National Center for Missing and Exploited Children

The National Center for Missing and Exploited Children (NCMEC), a federally funded nonprofit organization that serves as a national resource center for information related to crimes against children, operates a CyberTipline that receives child pornography tips provided by the public; its CyberTipline II receives tips from Internet service providers. The Exploited Child Unit investigates and processes tips to determine if the images in question constitute a violation of child pornography laws and provides investigative leads to the Federal Bureau of Investigation (FBI), U.S. Customs, the Postal Inspection Service, and state and local law enforcement agencies.
