In an effort to provide more reliable and effective communications with citizens, Frelinghuysen Township has implemented Swiftreach Networks, Inc. as our emergency notification provider.

Swift911™ is a system designed to make phone calls to specific people or areas in the event of an emergency or for sharing important information. Frelinghuysen Office of Emergency Management and other departments will use this system to notify citizens by phone of information regarding you or your property. The system can make thousands of calls in a minute to convey vital information. These messages may include information on floods, fires, water emergencies, road closures, missing persons, evacuation orders, and weather emergencies.

The Swiftreach Network Data has been provided by a third party data provider and only includes listed phone numbers in Frelinghuysen Township. It is important for residents and business owners to provide contact information such as unlisted, unpublished or cell phone numbers. Accurate numbers in the database help to ensure emergency information will be passed on to everyone in a timely manner.

Please note: This website it is not monitored on a 24/7 basis and if you are experiencing a true emergency you should dial 911.
