Telephone/Telecommunication Relay Services (TTY)

Telecommunication Relay Service equipmentTelecommunications Relay Service, also known as TRS, Relay Service, or IP-Relay, is an operator service that allows Deaf, Hard-of-Hearing, Speech-Impaired, and Speech-Disabled persons to place calls to standard telephone users via TDD, TTY, personal computer or other assistive telephone device.

Most TRS operators use regular keyboards to transcribe spoken voice as text for relaying. However, some TRS services may use stenotype or stenomask equipment, similar to those used by court reporters and closed captioning systems.

National TRS Number: 711

Just as you can dial 411 for information, you can dial 711 to access all telecommunications relay services anywhere in the United States. The relay service is free.
