USMC Transitions to Alert! Mass Notification System
The U.S. Marine Corps is committed to the safety and security of its Marines, Sailors, civilian and contractor personnel, families and tenants. To enhance our ability to communicate critical information during emergencies, all installations are transitioning from the AtHoc system to the new Alert! mass notification system, effective 1 April 2026.
Key Transition Dates
-- April 2026: The Alert! system goes live. All personnel should begin registering and verifying their information.
-- 1 May 2026: The AtHoc system will be deactivated and will no longer be used for mass notifications.
