A teletypewriter (TTY), also referred to as a Telecommunications Device for the Deaf (TDD), is used by people who are deaf or hard of hearing to communicate by telephone. A TTY is equipped with a small keyboard and display monitor which allows users to communicate by typing their message. The following University offices have a departmental TTY and the phone numbers and maps for these locations are listed below:
California Relay Service (CRS)
The 24-hour California Relay Service (CRS) allows hearing individuals to communicate with deaf or hard of hearing individuals. CRS operators transmit spoken and typed messages between TTY and voice callers, allowing people who use TTYs to communicate with other telephone users who do not have TTYs, and vice versa. Relay operators receive calls, speak the typed portion of the call to the non-TTY user, and type the spoken portion to the TTY user.
Voice to TTY: (800) 735-2922
If you don't have a TTY and want to call someone who does, call (800) 735-2922. Tell the operator the number you are calling. The operator will dial your call, then read to you what the TTY user types and type to them what you say.
TTY to Voice: (800) 735-2929
If you have a TTY and want to call someone who doesn't, call (800) 735-2929. Similarly, the operator will assist in placing the call, and will transmit information by either typing or speaking to the parties involved.
CRS operators can also facilitate conversations for individuals with speech impairments through Voice/Hearing Carryover (VCO/HCO). The individual with normal speaking ability should converse as usual by directly addressing the speech-impaired individual who would then converse by typing their part of the conversation and the CRS operator would then read it aloud to the other party.
For more information about accommodations for individuals with speech and/or hearing impairments, contact CRS customer service:
