Telecommunications Relay Service (TRS)

To make using Telecommunications Relay Service (TRS) as simple as possible, you can dial 711 to be automatically connected to a TRS communications assistant. It is fast, functional, and free. Dialing 711, both voice and TTY-based TRS users can initiate a call from any telephone, anywhere in the United States, without having to remember and dial a ten-digit access number.
