2019 AlertOC Regional Test

On October 17, 2019 Orange County residents will receive a Test Emergency Alert to their landlines and mobile devices. The test will replicate a large scale, multi-jurisdictional emergency requiring thousands of numbers to be called simultaneously across Orange County’s entire region. This is the ninth annual regional test of the system and will coincide with the annual Great Shakeout Exercise and 30th anniversary of the 1989 Loma Prieta Earthquake.

The distinctive feature of AlertOC is the ability for individuals to register multiple contact methods and addresses. Registrations of multiple contact methods and addresses of interest dramatically increase the ability to reach the greatest number of impacted community members within minutes. This enables landlines, cell phones and e-mail addresses to be incorporated into a single notification system.

Residents can do their part to prepare for emergencies by registering for AlertOC. The time is now to sign up and include cell phone numbers and e-mail addresses to be a part of the regional test. For more information or to register alternate phone numbers or e-mail addresses, visit
