9/11 attacks
911 (disambiguation)
Federal Communications Commission
National Emergency Number Association
United States

Chosen by the United States in the 1960s in place of the older British 999 number as a better way to avoid accidental calls from push-button telephones. It is officially pronounced "nine-one-one," not "nine-eleven," since "nine-eleven" refers to the 2001 attacks in New York and Washington. 9/11 is universally distinguished from 911 and usually refers to the September 11, 2001 attacks. Officially written as 9-1-1 in regulations and materials from the United States National Emergency Number Association and Federal Communications Commission, which is also advocated by some media style guides.
