The Federal Communications Commission (FCC) has adopted use of the 711 dialing code for access to Telecommunications Relay Services (TRS). The TRS permits persons with a hearing or speech disability to use the telephone system via a text telephone (TTY) or other device to call persons with or without such disabilities.
For more information about the various types of TRS, see the FCC’s consumer fact sheet at https://www.fcc.gov/consumers/guides/telecommunications-relay-service-trs . Please dial 711 to be connected to a TRS Center.
