AlertOC emergency notification system

September is National Preparedness Month

In honor of National Preparedness Month, the City of Mission Viejo is encouraging residents to register for its mass-notification system AlertOC. This targeted notification system will alert you when there is an imminent threat to life safety with required actions including evacuation orders. All landline phone numbers are preregistered in the system. You need to register your address, cell phone for calls and text messages, email address, and TDD/TYY devices. You can register multiple addresses, phone numbers, and emails including your home, work, etc.

Simply register your cell phone for calls and texts, email addresses and TDD/TY devices at AlertOC.com.

Along with registering for AlertOC, please pack emergency and "go" kits to sustain you, your family members and pets for several days without food, water, electricity and other essential items after a disaster.

Don't wait! Prepare now!

Additional information

Mission Viejo in 2008 was one of the first cities to implement AlertOC- a county-wide notification system funded by the County of Orange. The system gives City officials the ability to communicate with residents about time-sensitive issues, which could include planned and unforeseen emergencies or public-safety matters.

By registering with AlertOC, time-sensitive voice messages from the County or City in which you live or work may be sent to your home, cell or business phone. Text messages may also be sent to cell phones, email accounts and hearing impaired receiving devices.  To register as a Mission Viejo resident or business, click here.
