Which year did AT&T announce the establishment of 9-1-1 as the emergency code for use throughout the US?

In 1968, AT&T announced that it would establish the digits 9-1-1 (nine-one-one) as the emergency code to use throughout the United States. The code 9-1-1 was chosen because it best fit the needs of all parties involved. On February 22, 1968, Nome, Alaska implemented the 9-1-1 service.

Today, the 9-1-1 service within the United States is a vital part of the nation's emergency response and disaster preparedness system. In October 1999, the Wireless Communications and Public Safety Act of 1999 (9-1-1 Act) took effect with the purpose of improving public safety by encouraging and facilitating the prompt deployment of a nationwide, seamless communications infrastructure for emergency services. One provision of the 9-1-1 Act directs the FCC to make 9-1-1 the universal emergency number for all telephone services offered within each and every part of the country.
