411 is the traditional N11 code used in the North American Numbering Plan for local directory assistance. Callers dial this three-digit number to reach an operator or automated system that provides phone numbers and addresses for businesses and individuals. As internet search engines became ubiquitous, the volume of these calls plummeted, leading many carriers to phase out the service entirely.
Heard on the job
I tried calling 411 to get the dispatch number, but the carrier just played a recording saying the service was discontinued.
Insider tip
In workplace slang, asking someone for 'the 411' means asking for the details or gossip about a situation, a direct reference to this service.
