What happens when you call 9-1-1?
  • When you dial 9-1-1 your call is answered by professionally trained Telecommunicators. The 9-1-1 telephone system has an Automatic Location Identification System and an Automatic Number Identification System (ANI/ALI) which lets the call taker know the address and telephone number of the caller. If the caller is unable to speak, police will be dispatched to the location.
  • If you call from a cellular phone, ANI/ALI information may be available to the Telecommunicator if the cellular phone is Phase II compliant. Wireless Phase II requires carriers to provide far more precise location information - within 50 to 300 meters (approximately 170 to 1,000 feet). The cell phone vendors have different methods in which the cellular phone handset can provide the latitude and longitude for the caller, either through triangulation, GPS, or a hybrid of the two.
  • Try to remain calm and give your exact location or give the closest location or landmark you recognize.
  • The caller must be prepared to give the following information:
    • Which service is required - Fire, Police or Ambulance.
    • Where the emergency has occurred - the full address.
