ALERT! is a mass-warning notification system that sends registered users emergency warnings and other critical information, such as hazardous road conditions, reporting delays, and base closures due to severe weather. The notifications are mostly local but may also be theater-wide.

The system notifies users in several ways: as a pop-up on their workstation computer, an email to work and home addresses, a text message to their cell phone, and a voicemail to their work, home and cell phones.

Keep your information up to date. If you move to a new office or get a new personal cell number, make sure to go into ALERT! and provide your current information. It is effective in reaching community members with critical messages in real time, but its success depends on users’ input.


ALERT! is NOT optional. It is a Headquarters Department of the Army (HQDA) requirement to be a registered user.

All U.S. and non-U.S. military, civilian (all categories) and contractor personnel whose normal place of duty is on an Army garrison, installation, community, forward site and/or facility must register in ALERT! Each user can add their family members' contact information to their user profile.


If you are on a Department of Defense network computer, visit the Alert! website (recommend Google Chrome or Internet Explorer with email certificate to authenticate). For U.S. Army employees, click on the Blue Circle icon on your desktop computer to access ALERT! self-registration.

For users without a CAC or access to the DoD network access, please contact +32(0)2-280-9856 for registration.
