Are you having trouble using the telephone due to a hearing or speech disability?

Relay is a free telephone service that uses specially trained communications assistants to facilitate telephone calls between people with hearing and speech disabilities and other individuals. Calls can be made to anywhere in the world, 24 hours a day, 365 days a year. All calls are completely confidential.

To make a relay call dial 7-1-1. Once connected to the relay service, tell the communications assistant the type of relay call you wish to make. Or, you may dial the specific toll-free number for the type of relay service.
