Nixle Notification Service

The Denville Police Department has teamed up with Nixle in order to notify residents of important and valuable information. When we create and publish messages through the Nixle Community Information Service, Nixle will deliver this information to you instantly by cell phone text message and/or e-mail. Notifications can also be accessed online at Nixle's website.

Example messages may include information on recent crimes, descriptions of missing endangered persons, road closures and other relevant safety and community event information. Each message will be assigned one of four notification categories: Alert (time sensitive, need-to-know information that may require proactive action on your part), Advisory (need-to-know information that is not time sensitive), Traffic (for traffic related information) or Community (messages that are more informational in nature).

The service is reliable and spam free. More importantly, there are no hidden costs to sign up and use the service. However, if electing to receive text message notifications, standard text messaging rates apply as per your cellular contract. When signing up for the service, YOU decide what type of notifications you want to receive and whether you want to receive them by text message or e-mail.


  • What is Nixle?
  • Nixle is a Community Information Service dedicated to helping you stay connected to the information that matters most to you, depending on your physical location. You stay connected to your local police department, your children’s schools, your local community agencies and organizations, and the important information from other locations throughout the country that are relevant to you. Our service is built on the most secure, reliable, and high-speed distribution platform, ensuring that you receive trusted and immediate, geographically relevant information. Information is immediately available over your cell phone by text message, by email, and over the web. Your account can be customized so you receive the information that matters most to you. Whether it is where you live, work, or have friends or family throughout the country, the information is immediately available to you over your mobile phone, email and computer.
  • What messages would I receive through Nixle?
  • Only authenticated agencies and community organizations can securely publish information. There are four types of messages; Alerts (many would refer to this as an emergency type alert), Advisories (less urgent need-to-know information), Community Information (day-to-day neighborhood to community-level information), Traffic (very localized traffic information).
  • Do I have to register to use Nixle?
  • Anyone can view information by going to without registering. However, to customize the information you receive and the locations you receive it from, in addition to receiving information by text message and/or email you must set up an account. Once registered you can personalize your locations and your preferences, making the service fit your needs.
  • How does registration work?
  • We ask for routine information in the registration process. First set-up a user name and password. Then enter your address or closest cross-street. Then choose where you want to receive your information, whether by text over your mobile device or e-mail. Add as many locations as you would like at no additional cost. It’s that simple!
  • Do I have to give my mobile phone number?
  • No. However, the strength of the Nixle system is the delivery of real-time messages when you’re on the go. The best way to stay up-to-date with important information that could affect you and your family is to receive notifications by e-mail and mobile device.
  • I am a Sprint user and get a “Message Failed” response when I register using the 888777 shortcode. Why is that?
  • Sprint often disables access to all short codes (5 and 6 digit phone numbers) from their handsets. If you are Sprint customer, and you receive a message such as “Message Failed. Shortcode may have expired or shortcode texting may be disabled,” you may need to contact Sprint to enable your phone to send and receive messages from short codes. Nixle uses the 888777 short code to send you timely messages. Nixle does not charge for this service, but carrier message and data rates may apply. You may contact Sprint by dialing *2 on you cell phone or visiting
  • What do you do with my contact information? Will third parties contact me?
  • Information shared by users with Nixle is stored on a secure server in a secure facility. The company does not sell personal information to third parties. The privacy of your personal information is extremely important to us.
  • Can I enter multiple addresses?
  • You initially enter one address to begin the registration process. Once registered, you can click on “Locations” and add as many additional addresses (locations) as you would like at no cost. 
  • How many SMS (text) messages will I receive in a month?
  • This will vary depending on the number of notifications published. The service is simple to change SMS (Text) and email options.
  • Can I limit the number of SMS (text) messages I receive?
  • You can limit the number of SMS (text) messages by adjusting the type of messages you receive. You can opt out of any service except public safety Urgent and Important messages. For example, you can choose to receive Urgent and Important messages on your mobile device and e-mail and community news in just your e-mail.
  • How do I know an SMS (text) message I received is real?
  • Nixle goes through an extensive identity certification and authentication process before authorizing any agency or organization to publish information into the service.
  • Can I respond to a message?
  • No. However, if you wish to share a crime tip or information with the agency that sent you the message, contact details can be found by accessing the alert online.
  • Who do I contact for consumer support?
  • Please send all consumer support questions to: Please send all general inquiries to
  • How do I unsubscribe?

Neighborhood Watch

A community's residents are a vital piece of the puzzle in helping to keep a community safe. We strongly urge all of our resident's to immediately report anyone or anything that seems suspicious. Having concerned citizens acting as a second set of eyes and ears increases our effectiveness to respond quickly to any and all matters that may require police involvement. Think of it as having a police department of more than 16,000 officers!

We must, however, point out that we refer to you as an extra set of eyes and ears and not as an extra set of hands. For your own safety, you should never attempt to pursue or apprehend a suspected criminal. Simply report what you observe to the police department, providing as much descriptive information as possible.

Understanding that this neighborhood watch concept needs to work both ways, the police department has employed the use of the Nixle Notification Service to disseminate any important information to our citizens. We strongly encourage you to help spread the word about this service. Obviously this service will be more effective if a larger group of people receive the messages. Please ask your friends and neighbors who live in town to join the service by visiting
