How to Customize Your Calls Using “711 Choice” and a Customer Profile


When you dial 711, your call is automatically routed to a California Relay Service (CRS) provider and answered in English as a voice call. When appropriate, the call will be switched to the appropriate modality and language. But you can do more.

By establishing a “711 Choice Form,” you ensure that your call will always be routed to the relay provider of your choice. Also, the provider will answer your call in your preferred language and mode of communication. Once you establish your “711 Choices,” your information is shared with both providers. You do not need to provide your information again.

After you settle upon using the services of a certain provider, you may want to create a Customer Profile. This gives you more control over how your calls are handled.

Unlike 711 Choice where your choices are shared between providers, a Customer Profile is established with one provider. If you switch between providers, you will need to establish a Customer Profile with each provider.

Changing your 711 Choice is as easy as dialing any provider from your registered phone number and saying, “Please switch me from my current provider to a new one.” For more security and to change your choices at any time from any phone provide a password and the answer to a security question.

Register a 711 Choice Form with Your Preferred Provider

The 711 Choice Form is available from AT&T Relay and Hamilton Relay. You can switch to another CRS provider at any time by changing your 711 Choice preferences. Here is all you need to do to register.

Set up a Customer Profile with Your CRS Preferred Provider

Do you want to have more options than those provided on the 711 Choice Form? It’s easy.

You can set up a Customer Profile with a provider. All calls to CRS from your registered telephone number will be handled automatically according to your preference(s). However, a Customer Profile is specific to each provider.

If you like switching between providers, you will need to establish a Customer Profile for each individual service.

Your options include the following:




Call Blocking

You can choose to not allow pay-per-use calls and/or up to five (5) specific numbers to be dialed from your phone number.

Caller ID Blocking

You can prevent your phone number from being displayed on the phone of the person you call.

Delayed Response

If you need more time to read the TTY output, request extended response time so your call will not be disconnected while you are still reading.


Choose a male or female CA to relay your call.


Relay your calls in English or Spanish.

Long Distance Carrier

You can pre-select the phone company you want to use for long distance calls.


You can create a standard message you want left when you reach a telephone answering machine, e.g., this might include identifying yourself by name, requesting the person call you back, and providing the phone number of the California Relay Service, and your number.

Mode of Communication

Automatically connect to your mode of communication: TTY, VCO, 2LVCO, HCO, STS, VASTS, ASCII, or Voice.

Speed Dial

You can set up a list of most frequently called names and numbers. Later, you just state the name you want to call and the CA will dial that phone number.

Text Buffer

If you have difficulties following the typing speed of a CA, you can request to have the output on your TTY slowed down to between 10 and 50 words per minute.


Specify other preferences in how your conversations are conveyed. For example, requesting that the CA not describe background noises.

To set up a profile, call the Customer Service number of the  provider of your choice
