Emergency Alerts

Emergency notifications for the Town of Hollis are provided by the Hollis Police Department using the platforms CodeRED, Everbridge Nixle, and Nextdoor.  Please review the information below on each of the alert systems, which includes under which circumstances each system is used, as well as links to sign-up.  We recommend that you sign up for all three of these platforms CodeRED and Nixle.   

The Hollis Police Department is pleased to announce the use of a new social media platform called Nextdoor. Nextdoor is an advertising-supported social network of hyper-local online groups where neighbors post real-time updates. This platform will serve as a sort of digital “neighborhood watch” for those users who sign-up, and a megaphone for Hollis Police Department, who aims at providing the highest levels of police services to the community.

On neighborhood feeds through Nextdoor, the Hollis Police Department will be able to share urgent alerts and community events, just like they might on other sites like Facebook and Twitter. Unlike other platforms, though, Nextdoor will allow the Hollis Police Department to geo-target posts to reach particular residents who have verified they live in the area.

We hope you consider enrolling in this useful public safety application.  Please click on the Nextdoor image below to register for the application.

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, like the Hollis Police Department, 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 www.nixle.com 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.  Here is a quick and easy link to sign-up for Nixle:


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.



The CodeRED® system will be used to send critical communications, from evacuation notices to missing child alerts.
