TeleBraille Relay Service

800-735-2966 for English
800-520-7309 for Spanish

You can use a TeleBraille device or TTY with a large visual display to make relay calls. This service allows you to read the phone conversation in braille or in a large font size at a 15 WPM transmission speed. If desired, you may specify a different WPM transmission speed to the communications assistant.

The communications assistant reads aloud the message you typed to the other party, and then types what the other party says to you.

This service is designed for people who are DeafBlind or Deaf with Low Vision.

This relay service is available in English-to-English, Spanish-to-Spanish and Spanish-English/English-Spanish Translation. For the Spanish relay calls, please notify the communications assistant that this is a TeleBraille Relay call, so that the correct transmission speed could be used.

The TRS Customer Profile allows you to store your relay call preferences and helps speed up call processing.

How does TeleBraille Relay work?

It’s simple!

Dial 711 (or 800-735-2966 for English, 800-520-7309 for Spanish-to-Spanish or English-to-Spanish/Spanish-to-English Translation) and the communications assistant will answer with “Relay Missouri”.

Type the area code and telephone number you wish to call and type “GA” (“Go Ahead”). The communications assistant will dial the number and connect to the other party.


The other party listens and speaks. They say “GA” (“Go Ahead”) to indicate that it is your turn to respond.


The communications assistant conveys the other party’s voiced message by typing it to you.


You read the other party’s voiced message on your TeleBraille device or TTY with large visual display, and then type your response, which the communications assistant reads aloud. Type “GA” (“Go Ahead”) at end of each message. The “GA” indicates that it is the other party’s turn to respond.

To conclude the call, type “GA to SK” (“Stop Keying”) to indicate that you are ready to hang up.
