Alert LA County is the countywide emergency notification door

Alert LA County is the countywide opt-in emergency notification door. Ready LA County explains that it can send emergency alerts by text, email, or phone, and that people can add the alert phone numbers to their contacts after signing up.

This matters because Los Angeles County has many city systems layered with county, sheriff, fire, school, employer, and campus alerts. A person who lives in one city, works in another, and helps family somewhere else may need more than one alert source.

Use Alert LA County as the broad county layer, then add city alerts where they exist. Keep the account information current, especially if you move, change numbers, or care for someone in another neighborhood. For an active incident, use current official messages, evacuation maps, and public safety instructions over old social posts.
