Emergency Notification System (ENS)

Emergency Notification System (ENS)

Sign-up at to receive messages about imminent threats and hazards!

This system allows residents of the county and all cities within the county to be notified of an emergency situation in a variety of ways, including on their cell phone, home and work phone and by text message and email.

How it works:

  • A brief message is recorded by the agency that answers 911 calls in your area.
  • The system allows the agency to select who is called by defining an area on a map or by inputting a range of addresses.
  • The message is then ‘launched.’ The system automatically calls each landline number in the selected area, playing the recorded message when the phone is answered.
  • The system also calls other phone numbers, sends text messages, and sends emails to individuals who have “opted in” to the system for additional notification.
  • If the phone is busy, the system will try again. If an answering machine is encountered, the system will attempt to leave a message.
  • If a TDD signal is encountered, the system will leave a TDD message.
  • When you receive an emergency alert call:
    • Listen carefully to the information in the recorded message. It will contain:
      • The name of the agency that recorded the message.
      • Details as to the nature of the impending danger.
      • What action you need to take.
    • You may repeat the message by following the system prompts. Do not hang up in the middle of the message; the entire message must be left for the system to show it was received.
    • If you have signed up to be notified in multiple ways (work phone, cell phone, and text message, for example) the system will stop trying to reach you once you acknowledge that you have received the message in one of these ways.

You should know:

  • If you have a telephone device used to block telemarketers, or your phone is blocked to unknown callers, you will not receive the ENS message.
  • The system is free to anyone who lives within Boulder County, including any of the cities or municipalities in the County. Participants are responsible for any fees charged by their provider for text messaging.
  • When calling your land line phone, the ENS system generates your phone number to the local public safety agency. If you opt-in to the system for additional notifications, the information you provide will only be used for emergency purposes. It will never be shared with any other organization or used for any other purpose. Your privacy is protected.
  • You do not need to sign up or update information for land line telephones at your home, if your land line is with a company that reports your number for 9-1-1 services. Some cable and VoIP providers do not subscribe to the 911 database. To know for certain, inquire with your phone company.
