Alert LA County is a free mass notification system for Los Angeles County residents and businesses.  The Los Angeles County Sheriff’s Department uses Alert LA County to contact the public during a Countywide emergency, and in communities that they directly serve as the law enforcement agency. Alert LA County sends shelter-in-place instructions, evacuation, and other emergency messages. It has accessibility features for people with disabilities and others with access and functional needs. You can also select your preferred language for notifications.

Visit Alert LA County or click on the registration link to add cell phones, VOIP phones, emails, and additional addresses where you would like to receive alerts.  The Alert LA County database automatically includes listed and unlisted land line telephone numbers, so they do not need to be registered.
