What is 911? Nine-one-one is the number most people in the U.S. and some international countries call to get help in a police, fire or medical emergency. In some places, you may be able to be connected with Poison Control by calling 9-1-1, but you should check with local officials in your area to make sure. A 9-1-1 call goes over dedicated phone lines to the 9-1-1 answering point closest to the caller, and trained personnel then send the emergency help needed. What is Enhanced 911? Enhanced 9-1-1, or E9-1-1, is a system which routes an emergency call to the 9-1-1 center closest to the caller, AND automatically displays the caller's phone number and address. The 9-1-1 call taker will typically ask the caller to verify the information, which appears on his or her computer screen. In many areas, phone number and location information is not yet available for 9-1-1 calls made from a cellular/ wireless phone.
