How to Register

What if you haven't registered?


  1. If you use ACR, you are connected to the telephone company as usual.

  2. If you do not use ACR, your local calls and in-prefecture long-distance are carried via NTT East or NTT West, and your out-of-prefecture long-distance calls are carried via NTT Communications.

Customers have a choice in four categories.
Choose and register one telephone company in each of the four categories.

(1) Local call    (2) In-prefecture long-distance
(3) Out-of-prefecture long-distance     (4) International


Once you've completed the registration procedure and service starts, you'll be able to make calls via those telephone companies without the bother of dialing an access code. The table has a list of the telephone companies that you can register.
