Usage notes

The first 911 call in the US was made in Haleyville, Alabama, on February 16, 1968. Spoken as "nine-one-one," never "nine-eleven," which refers to the September 11, 2001, attacks. Most US areas now accept text messages to 911. Calling 911 from a mobile phone works even without a service plan.
