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

To separate combined KDDI billing, you can complete the procedure at au Style/au shop, by mailing the application form, or through My au (Web).

For details, please refer to the information below.

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

The contract holder of the line that you want to be billed separately must visit the store.
If you would like to have separate billing for all lines with different contract holders, all of the contract holders must visit the shop in person.
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.
