About MassRelay

MassRelay is a free, confidential 24/7 service enabling hearing people or people who do not use a text telephone (TTY) to communicate over regular telephone lines with people who are deaf, hard-of-hearing, late deafened, or speech disabled.

A Relay Operator (OPR) will complete your call, dialing the person you wish to contact and then stay on the line to relay messages electronically via a TTY or verbally to people who can hear. OPRs provide exact transcriptions of what they hear and speak what is typed to them, unless the caller directs them to do otherwise. View Process.
