Announcements

Sharing of customer information between mobile phone and PHS service providers

Mobile phone and PHS service providers may exchange the names, addresses, and other personal information of customers such as those indicated below.

Customers who owe an unpaid balance to another carrier after canceling their contract
Senders of unsolicited email (spam)
Customers whose service has been suspended due to refusal to respond to requests for identification verification in accordance with Article 11 of the Mobile Phone Improper Use Prevention Act

Multiple contracted lines under the same name for individual subscribers

To prevent large numbers of improper contracts under the same name, individual subscribers are generally limited to a total of five contracted smartphone and mobile phone lines under the same name. The number of lines that you can apply for may vary depending on the content of the application.

Provision of personal identification document information when subscribing

When personal identification documents such as driver's licenses are presented at the time of subscription, au may provide the information contained in such documents to the relevant issuing authority to confirm the validity. The aim of this measure, which has been in place since December 1, 2008, is to prevent the use of mobile phones with contracts that were fraudulently obtained with forged identification documents, in criminal activities such as bank transfer fraud. We appreciate your understanding in regard to our efforts to ensure reliable identity verification.

Changes to personal identity verification methods when subscribing

Please note that in accordance with the "Act for Identification, etc. by Mobile Voice Communications Carriers of Their Subscribers, etc. and for Prevention of Improper Use of Mobile Voice Communications Services" (also known as the "Mobile Phone Improper Use Prevention Act"), which came fully into effect on April 1, 2006, we have changed our methods for verifying the identity of individuals when signing up for a new contract or transferring ownership.
