Text Telephone Relay or Telecommunications Relay Service (TTY/TRS)

TTY is for individuals who are deaf, hard of hearing, DeafBlind, or have speech disabilities and wish to communicate with a hearing person who uses a standard telephone. TTY relay calls are generally made using a text telephone, also known as 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 call the Federal Relay TTY Toll-Free Number to reach a Communication 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.
