Telecommunications Relay Services (TRS)

for Hearing and Speech Disabled Customers

Important Changes Coming to Michigan Relay Services 


Dial 711 for Michigan Relay Service


On February 6, 2015, customers who are deaf, hard of hearing, deaf-blind or have difficulty speaking and use the Michigan Relay Service will be served by a new Telecommunications Relay Service (TRS) provider. At 5PM EST on this date, we will transition from AT&T Relay to Hamilton Relay as the contracted provider. AT&T has discontinued the provision of TRS services. 


We have taken care to minimize the impact on users of TRS by selecting one of the country’s leading TRS providers.  On February 6, 2015, the existing toll-free Michigan Relay Service numbers will be disconnected, however, callers who require the use of traditional relay services in Michigan, now or in the future, should dial 7-1-1 to access the Relay center.  Dialing 7-1-1 from any number within the state of Michigan will connect the caller directly to a specially trained Communication Assistant who will be ready to place the relay call.

711 Relay service makes it possible for individuals who are deaf, hard of hearing, deaf-blind or have difficulty speaking to make and receive telephone calls. Relay calls are simple — just dial 711 and you will be connected with a highly trained Communication Assistant (CA) that will facilitate your call. There are no restrictions or time limits on any call and 711 Relay service is available 24/7/365. Emergency calls should continue to be directed to existing local TTY-911 numbers.


Whether you're making personal calls or business calls — all relay calls are confidential and there are no records or recordings of any relay conversation.


Traditional relay calls are based on the TTY (also known as a TDD or text telephone). However, there are many different types of relay calls, such as Voice Carry Over and Hearing Carry Over, that accommodate individual calling preferences.


Regardless of how you connect, the CA will "voice" everything you type to the other party — and type everything the other party says so that you can read the conversation on your screen. The CA is an invisible link between the calling parties.


Customers who use a coin telephone to make phone calls through their state TRS should know about two pricing policies that became effective in November 1995.


  • Local pay phone calls made through the TRS Center are free


  • When you use a calling card to make long distance calls from a pay phone connected through TRS, you're not charged more than the standard coin rate.

Frequently Asked Questions


Q. What will happen if I dial one of the existing Michigan Relay Service toll free numbers after February 6, 2015?

A. You will get a recorded message that states, "We're sorry. The number you have dialed has been disconnected and is no longer in service. Please dial 7-1-1 or contact your local telephone company for assistance."


Q. I currently have the Michigan Relay Service toll free number programmed in my TTY. 

Will I need to reprogram my TTY to dial 7-1-1?

A. Yes. You will need to reprogram your TTY to dial 7-1-1 before February 6, 2015 otherwise; you will be unable to connect to the relay service to complete your call.


Q. What will happen to my relay profile? Will it still work after February 6, 2015?

A. Your profile will be transferred to the new relay provider in accordance to the Federal Communications Commission requirements for Relay Service so that your relay calls can continue to be handled as you have indicated in your relay profile. You will not need to do anything different.


Q. Now that the toll free numbers will be disconnected, how can I be sure that I will be connected quickly to the type of relay service I prefer such as Speech-to-Speech or Spanish Relay?

A. All relay calls are available by dialing 7-1-1 including Voice Carry Over, Hearing Carry Over, Speech-to-Speech, or Spanish Relay. If you currently do not have a relay profile, you are encouraged to set one up to ensure your calls are routed quickly to the Communications Assistant most qualified for your type of call.


Q. Who should I contact if I have more questions about this change to the Michigan Relay Service?

A. If you have any additional questions about this change to the Michigan Relay Service, please contact your local telephone carrier or you can contact the Michigan Relay Customer Service number at 800-432-0762.
