If you dial 9-1-1 from a landline (a house phone), the owner's address information may populate to a dispatcher which can aid in location of the caller. However, when calling from a cell phone (mobile), 9-1-1 does not get any type of name, address or any other type of ownership information. 9-1-1 will at the minimum, receive the coordinates of the tower that your signal is hitting (known as Phase I). Most newer model cell phones will allow cell phone carriers to send 9-1-1 more precise coordinates, known as Phase II. This location is more specific to your location, but may not be exact.
When a Smart911 profile is created, the information you have added will populate to the dispatchers and allow a quicker confirmation of your location and gives the dispatchers vital information at their fingertips.
