Sign up for the LA County emergency mass notification system that will be used to contact County residents and businesses via recorded phone messages, text messages or e-mail messages in case of emergency. The system, called Alert LA County, will be used by the County’s Emergency Operations Center to notify residents and businesses of emergencies or critical situations and provide information regarding necessary actions, such as evacuations. The system utilizes the telephone companies’ 911 database and is able to contact land-line telephone numbers, whether listed or unlisted. If the call is picked up by an answering machine, the system will leave a recorded message. If the number called is busy or does not answer, the system will redial the number in an attempt to deliver the message. The system is also TTY/TDD compatible.
Because the Alert LA County system uses the 911 database, only land-line numbers are automatically included in the system. If you have a cellular or Voice over IP number and would like to be notified on that device, or if you would like an e-mail notification, you must register those telephone numbers and/or e-mail address by completing the registration form below.
Because the Alert LA County system uses geomaping, each telephone number and/or e-mail address can only be associated with one street address in the system.
Each telephone number and e-mail address registered below will be contacted only when the street address it is associated with is impacted by a disaster or emergency.
