Distribution Process
The California Highway Patrol will distribute AMBER Alerts to law enforcement, broadcasters, National Center for Missing and Exploited Children (NCMEC), Lottery, Ports of Entry, and members of the public who have registered to receive the alerts. Those alerts will be sent to computers, cell phones and text messaging devices.
CHP will use the Emergency Alert System (EAS) to initially notify California broadcasters of the alert.
CHP will also post the alert on its website www.chp.ca.gov.
CHP will send out flyers to law enforcement agencies and businesses throughout California and surrounding states.
California Department of Transportation will distribute the alerts on Changeable Message Signs (CMS), and Highway Advisory Radio (HAR) transmitters.
Media outlets will also post alerts on their websites.
NCMEC will disseminate the alerts through secondary distributors, i.e. Internet providers, Facebook, trucking associations, airport security, Twitter, Nixle, etc.
Numerous private businesses have agreed to put the alerts on their electronic signs.
APBnet
APBnet is a web-based system that captures and immediately distributes color photographs and images to law enforcement agencies, media outlets, and other organizations. In addition, the system is capable of transmitting information via facsimile to business, hospitals, schools, media outlets, and agencies. The APBnet system can be used to quickly disseminate information regarding a child abduction case throughout the state.
When the CHP receives word of a confirmed child abduction which meets the AMBER Alert criteria, it can post Critical Reach flyers, photographs and other pertinent information on the department's Computer Aided Dispatch (CAD)/media Web site (cad.chp.ca.gov) and public Web site (www.chp.ca.gov).
Emergency Digital Information Service (EDIS)
EDIS delivers official information about emergencies and disasters to law enforcement, news media and the public in California. Electronic emergency bulletins posted to EDIS are available by e-mail and pager from various providers, who voluntarily provide this service. Bulletins are posted on the EDIS Web site (http://edis.oes.ca.gov) for access by the media, law enforcement agencies, and the public.
Wireless Emergency Alerts Program (WEA)
The Wireless Emergency Alerts will allow consumers with WEA-capable smartphones and feature phones to automatically receive free AMBER Alert messages, along with Presidential and Imminent Threat Alerts. When a subscriber with a WEA enabled cellular phone is within range of the activated cell tower they will receive the AMBER Alerts, even if the wireless customer is not from the area. The program is an "opt out" program, meaning subscribers do not have to enroll in the program to receive alerts. The WEA AMBER Alert notification is automatically sent from National Center for Missing and Exploited Children (NCMEC) at the time of the AMBER Alert activation. The message includes an audible tone followed by a text-like message.
