7-1-1 is assigned nationwide for access to Telecom Relay Services (TRS). TRS allows persons with a hearing or speech disability to use the telephone. These consumers use special telephone devices known as a text telephone (TTY) or a telecommunications device for the deaf (TDD). If you want to call someone who uses a TTY/TDD, pick up your phone, dial 7-1-1, and you will be automatically connected to the TRS operator. The operator will connect you to the TTY/TTD user and read aloud the text typed by the TTY/TDD user. When a TTY/TDD user dials 7-1-1, an operator places the call to the voice user, and then relays the conversation by transcribing spoken content for the TTY user and reading text aloud for the voice user. If in an emergency situation, call 9-1-1 and they will connect caller to 7-1-1 services.
