Delaware Emergency Notification System (DENS)
Get Notified Before Disasters Strike!
The Delaware Emergency Notification System (DENS) is the primary system for public warning and emergency protective action information in the State of Delaware.
Municipalities, Counties, and State & Federal agencies utilize DENS to inform and warn the public during emergencies that may adversely affect the health, safety, and welfare of Delaware citizens.
DENS allows local 911 centers and emergency managers to send messages to communities or larger affected areas.

Landlines
DENS allows emergency voice messages to be delivered to a home or business within the traditional landline telephone network. If you have a landline phone, your address and phone number are already in the DENS database.
Cell Phones and Voice over Internet Protocol (VoIP) Phones
Cell phones are not automatically enrolled in DENS To receive emergency alert messages on your cell phone, you must register! Multiple phone numbers may be registered.
Emergency officials urge those with new phone numbers, unlisted numbers, cell phones, VoIP phones, and new house addresses to register with the DENS system.
Registering your phone enables DENS to geocode your phone number to your home or work address and can send emergency alert messages directly to your cell phone and VOIP home phones. Post office boxes may not be used to register addresses because they are not affiliated with your physical location.
DENS Alert Notifications
In the event a phone line is busy, the DENS system will try to deliver the message two additional times. If an answering machine or voicemail are reached, the DENS system will still deliver emergency messages.
If an emergency message has a text or e-mail included, registering your phone information will allow you to receive the text or e-mail message.
Wireless Emergency Alerts (WEA)
WEAs can also be sent through the DENS system and use the location of your cellphone to determine if you are in an intended emergency messaging area.
While you do not need to register your phone number to receive a WEA, not all cellphones can receive them. Wireless service customers should check with their wireless service provider to find out if their cell phone or mobile device is WEA-capable.
Additional information about WEA can be found on weather.gov.
