Standard Text Telephone (TTY)


TTY User Dial: 711 or 800-659-2656


Standard TTY Relay Service is for people who are deaf, hard of hearing, or have speech loss and wish to communicate with a hearing person who uses a standard telephone.

Standard TTY relay calls are generally made using a text telephone, also known as a TTY, which is a communications device equipped with a keyboard for typing messages and a screen for reading messages. A TTY device connects to a standard phone line. TTY callers dial Relay Colorado to reach a Communications Assistant (CA) who processes their call.

Once connected, the TTY user types messages to the CA, who relays the conversation by reading it aloud to the hearing person. The CA then listens to the hearing person’s reply and types it to the TTY user.

Hearing people, or standard telephone users, can learn how to call a hearing or speech disabled person who uses a TTY.
