7-1-1
From Wikipedia, the free encyclopedia
In Canada and the U.S., the 711 telephone number is used for the Telecommunications Relay Service to translate from TDD for the deaf to speech, and vice versa. The relay service allows hearing-impaired people to converse with the hearing over the phone through an operator. 711 is one of eight N11 codes for abbreviated dialing in the North American Numbering Plan. In the U.S., every phone company is required to connect persons who dial 711 to a TRS call center from a working number, though this may not yet apply to VOIP telephony.
