7-1-1 is the national number used for accessing Relay Services throughout the United States. 

Anyone using landline technology such as a teletypewriter (TTY/TDD/VCO/HCO) needs the Relay Service
to connect with you on any phone, landline or cellular.  People with speech impairment also use the Relay Service. 
If a Relay service user is calling you, the human Calling Assistant (CA) would explain what is going on in 
simple terms and the call will proceed. 
When calling a Relay user, that person should give you instructions to use 7-1-1, and their landline phone number. 
Upon dialing 7-1-1, you will hear a recording that explains the Relay Service. Stay on the line to 
connect to the human CA and provide them with the landline telephone number of the user. 
Relay is a turn-taking system. The users are encouraged to finish each communication with "GA" (Go Ahead). 
This turn-taking goes back and forth until the conversation is done and both parties say or type SK which means Stop Keying (hang up). 
Please note that 7-1-1 is NOT an emergency number and should not be confused with 9-1-1 for emergency calls. 
In case of emergency, dial 9-1-1 directly to get help fast.

Yep, it's that simple! You can access the AZRS through the toll-free number.

Relay Conference Captioning (RCC) hours of operation have been expanded for Arizonans. You may now utilize RCC for teleconference calls during these new hours:

M-F 8a-9p and Sat 8a-2p

RCC is a free service provided by ACDHH/AZRS for multi-party teleconference calls where one or more Arizonans on the call needs captions due to hearing loss. RCC is not to be used in place of a CART captioner. RCC must be requested 48 hours in advance of the teleconference call. RCC is not for 1:1 phone calls. For 1:1 phone calls, please use captioned phones or captioned apps.
