I would like to undo my combined billing (Split billing)

If you would like to undo your KDDI combined billing/consolidated billing, please do the procedure at the nearest au Style/au shop.

Important notes

  • If there is an outstanding bill, you will not be able to separate the bill.
  • Please note that some discounts such as au Matome talk/Combo discounts may no longer apply. Please check the applicable conditions before applying.
  • Split billing for electricity/gas cannot be processed in-store. Please contact the chat support for inquiries.

Procedure at an au Style/au shop

  • The contract holder of the line that you want to be billed separately must visit the store.
  • If you would like all lines with different contract holders to be billed separately, all the contract holders should also come to the shop for the procedure.
  • If a family member other than the contract holder is to be the billing recipient (for example, if the contract holder is a minor and the guardian is to be the billing recipient, or if a direct debit from a family member's bank account is to be set up), please have both the contract holder and the family member come to the shop.

For your reference

If it is difficult for you to come to the store to do the procedure, please contact our chat support for inquiries.

  • All of the indicated amounts exclude tax unless otherwise specified.
