Nine-one-one is the number most people in the U.S. and some in 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 networks to the appropriate 9-1-1 answering point (PSAP) for the caller's location, and trained personnel then send the emergency help needed.
