The California Highway Patrol is responsible for the statewide coordination of the Amber Alert Emergency Alert System and the other emergency response activities associated with child abduction. State law dictates when an Amber Alert can be issued. If you see a child who is the subject of an Amber Alert, call the number on the alert or contact your nearest law enforcement office.
Mobile Phone and Hand Held Amber Alerts
Amber Alerts are now available to cell phone users via the wirelessamberalerts.org website. Sign up for the service to receive Amber Alert notifications on your handheld devices. You just might save a child's life.
