Which phone number does KDDI use when contacting customers?

KDDI may contact the customers by phone or text message (SMS) to provide information about special offers.

In such cases, we will contact you using one of the phone numbers currently registered with KDDI.

Important notes

  • The initial "0" of the caller's phone number may also be displayed as "+81 (Japan's country code)" .

    Example: "050 **** **** " may be displayed as "+81 50 **** ****"

  • If you receive a call from a number claiming to be an agency or similar entity not listed on this page, and you feel suspicious about it - for example, if they ask to confirm your contract details or fail to provide clear answers to your questions, please avoid sharing any personal information.
  • Even if the sender's phone number appears to match the legitimate numbers listed on this page, please be aware of that as it may occasionally be falsified through impersonation or spoofing.

    If you receive any contact that you do not recognize or find suspicious, please ensure that you do not open any links or URLs provided in the message.
