Emergency Alerts

Denver's Emergency Preparedness Network (EPN) is an instantaneous notification system, which eliminates the need for Denver 911 to individually notify residents of large scale emergencies or disasters. The system geographically identifies, warns and provides instructions to citizens in times of crisis such as in the case of a missing child, severe weather, toxic spill, or terrorist threat.

How it Works

The EPN system uses the 911 database as its source of telephone numbers.  Both published and non-published phone numbers are used to immediately notify residents and businesses about emergency situations in their vicinity. 

*Note:  If an answering machine picks up, the system will leave a message. If you block unknown numbers from your phone, the EPN system message will also be blocked.
