AlertOC is a mass notification system designed to keep Orange County residents and businesses informed of emergencies. By registering with AlertOC, time-sensitive voice messages from the City of Irvine may be sent to your home, mobile, or business phone. Text messages may also be sent to mobile phones, e-mail accounts, and hearing impaired receiving devices.
Public mass notification systems have become a critical component of emergency preparation and response. Public Safety officials utilize the system to rapidly send out messages when there is a perceived, emerging, or imminent situation that may require community action, such as evacuation.
Based on the severity of the event, AlertOC may be used to contact residents by one or all of the following methods:
- Home phone
- Work phone
- Mobile phone
- Text (SMS) message
Residents are encouraged to sign up for this important notification service at AlertOC.org.
Only authorized public safety officials are allowed access into the system; however, if you would like to know how we keep your information secure, visit our Privacy Policy page.
