This caused difficulties, inconvenience, and delays in rescue operations.

In 1964, the case of a 28-year-old girl being murdered in the U.S. led to calls for establishing a nationwide emergency response procedure. In 1967, the U.S. Judiciary and Legal Committee announced the use of a single emergency phone number.
AT&T proposed the number 911 because it wasn't duplicated with area codes or service codes. Also, it's short, easy to remember, and can be dialed quickly. In 1968, the U.S. Congress officially recognized 911 as the nationwide emergency phone number. Since then, the 911 system has expanded rapidly and is still in use today.
