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. 

What is Alert!?

Alert! is a comprehensive mass notification system designed to transmit alerts and warnings messages of hazards and threats through multiple channels, including:

-- Desktop pop-up notifications
-- Telephone calls (work, home, and mobile)
-- SMS text messages
-- Email (work and personal)

This system ensures that the chain-of-command can rapidly disseminate information during any all-hazards and threat events, in compliance with Department of Defense Instruction 6055.17, which mandates that 90 percent of the primary population be notified within 10 minutes of an emergency. 

Action Required for All Personnel

To ensure you receive these time-sensitive alerts, all military, civilian, and contractor personnel must register and maintain their contact information in the Alert! system.

-- New Users: Upon logging into a .mil computer starting in April, you will see a pop-up window prompting you to register. Please follow the on-screen instructions to create your account and input your contact details.
--Migrated Users (from AtHoc): Your basic information has been migrated to the Alert! system. Please verify and update your details by locating the Alert! icon (a blue speech bubble with an exclamation point) in your computer’s system tray, double-clicking it, and selecting "Edit Client Info."

It is mandatory to review and verify your contact information every 90 days to ensure it remains current.
