: 為什麼美國人要打911
http://en.wikipedia.org/wiki/9-1-1
In 1968, a solution was agreed upon. AT&T chose to implement the concept,
but with its unique emergency number, 9-1-1, which was brief, easy to
remember, dialed easily, and worked well with the phone systems in place
at the time.(1968年, AT&T決定將緊急電話設為911, 因為它簡短又好記, 而且適
合當時的電話系統.)
How the number 9-1-1 itself was decided upon is not well known and is
subject to much speculation by the general public. However, many assert
that the number 9-1-1 was chosen to be similar to the numbers 2-1-1
(long distance), 4-1-1 ("information" or directory assistance), and 6-1-1
(repair service), which had already been in use by AT&T since the 1920s.
(為何號碼是911眾說紛紜, 不過最有可能的原因是和當時其他服務電話一致, 例如
211是長途台, 411是查號台, 611是障礙台, AT&T自1920年代就開始採用這些號碼了.)

台灣與南韓則沿用日治時期「119」（發音與「火火苦」相近）。
1945年之前的日治時代，台灣的火警電話本來就是「119」，反而是戰後國府領台後
才改用「09」，但因民眾不習慣，經常報案延誤，所以在1959年12月1日才又改回使
用「119」。
