TRENTON, N.J. - Mercer County is expanding its Alert-MercerCounty system to include cellular telephones as well as land lines.

Alert-MercerCounty is a free community notification system used to deliver outbound messages in the event of an emergency. The system employs a combination of database and mapping technologies to pinpoint a specific geographic area and deliver the appropriate message to residents in the targeted area. The Alert-MercerCounty self-registration system is strictly to register wireless cellular phones, none of which are already in the current database. This is especially important for those households that now rely exclusively on wireless cellular phones and no longer have traditional landlines.

If you would like to be contacted on your cellular phone, you must register your number at Please note that the service is for Mercer County businesses and residences only. Calls regarding property or situations outside the County are not covered. Because the system works off locations within the County, phone numbers can be outside of Mercer County but you must enter a valid address within the boundaries of the County to be eligible for the service.
