7-1-1
In Canada and U.S., the 711 telephone number is used for the Telecommunications Relay Service to translate from TDD for the deaf to voice, and vice versa. The relay service allows deaf people to easily speak with the hearing over the phone.
For more information, please see Telecommunications Relay Service.
