America's Missing Broadcast Emergency Response (AMBER) Alert system broadcasts information on missing children, so the public may help find them in the critical early hours of the investigation.
Sign up for AMBER Alerts through the National Center for Missing and Exploited Children (NCMEC). You will find ways to get alerts through Facebook, Twitter, Google Alerts, phone app, and Yahoo Alerts.
How do AMBER Alerts work?
"Once law enforcement has been notified about an abducted child, they will decide whether or not to issue an AMBER Alert based on their AMBER Alert program's criteria.
They will provide the geographic area where the alert should be issued as well as any available information about the child, abductor or suspected vehicle used in the abduction.
Once issued, the alerts are distributed by broadcasters and transportation agencies. They are also sent to the National Center for Missing & Exploited Children, which redistribute the alerts, per a request by the U.S. Department of Justice, to a network of secondary distributors that includes Internet service providers, digital billboards, truckers and others."
