When did the 911 become the national emergency number??

Answer 1

The number "911" is the universal emergency number for everyone in the United States. In 2000, approximately 150 million calls were made to 911, according to the National Emergency Number Association (NENA). If you were born in the 1960s or later, 911 was ingrained in you during childhood, and those born prior to 1968 have been exposed enough to 911 that it has become second nature.
Prior to 1968, there was no standard emergency number. So how did 911 become one of the most recognizable numbers in the United States? Choosing 911 as the universal emergency number was not an arbitrary selection, but it wasn't a difficult one either. In 1967, the Federal Communications Commission (FCC) met with AT&T to establish such an emergency number. They wanted a number that was short and easy to remember. More importantly, they needed a unique number, and since 911 had never been designated for an office code, area code or service code, that was the number they chose.
