MassGIS has created a "master address database" (MAD) that is used for compiling, standardizing, editing and maintaining addresses for the Next Generation 911 system project. MassGIS' goal is to provide municipalities, residences, businesses, and application developers with the most comprehensive list of standardized addresses for cities and towns throughout the Commonwealth.
MassGIS is working very closely with the State 911 Department in the state’s Executive Office of Public Safety and Security on the Next Generation 911 Emergency Call System. MassGIS developed and is maintaining the map and address information that are at the heart of this new system. Statewide deployment of this new 9-1-1 call routing system was completed in 2018.
