Every house has an assigned identifying number that displays your home address. Although these numbers are important for the mailman and guests visiting you, house numbers are crucial for emergency personnel when responding to the location of an emergency.
When 911 is called to report an incident or emergency, dispatchers receiving the call have a key job to do by determining where the emergency is taking place. The call takers must then relay the location to the proper emergency responder such as law enforcement, the fire department, or ambulance. While emergency personnel are responding to the location of the incident, they are relying on accurate information from the dispatcher to ensure that they are going to the correct address.
