Reverse 911 is a public safety communications technology used by public safety organizations in Canada and the United States to communicate with groups of people in a defined geographic area. The system uses a database of telephone numbers and associated addresses, which, when tied into geographic information systems (GIS), can be used to deliver recorded emergency notifications to a selected set of telephone service subscribers.[1]

Reverse 911 was developed by Sigma Micro Corporation, later known as Sigma Communications, in 1993.[2] After a number of corporate acquisitions, Motorola Solutions ultimately gained ownership of the technology and rights developed by Sigma, and Motorola has folded Reverse 911 into their Vesta suite of public safety systems.[3]
