This article provides an overview of the Telecommunication Relay Service (TRS), how it works, and the TeleType devices that are compatible with the service for hearing-impaired users.

TRS allows a person with hearing or speech disabilities to place and receive long and long-distance telephone calls. It is available in all 50 states, the District of Columbia, Puerto Rico, and the U.S territories.

With TSR, hearing or speech impaired users can dial 711 to reach a Communications Assistant (CA) who then will relay the call to the intended party.

Note: There are no additional charges for TRS calls.
