To link your PayPay account, your registered information (name in katakana, date of birth) for both services needs to match exactly.
If you can't link your account, it may be because:
• There were extra spaces included in your name in katakana.
Note: Make sure there are no extra spaces included before or after your name.
• Characters of different sizes were used for your name in katakana. For example, if your name is John and is written as ジョン, don't write it as ジヨン.
Note: If your name is registered differently in katakana on PayPay and LINE Pay, you will need to unify how your name is written on both services.
Keep the above points in mind and see if there are any differences in your registered information for both services.
You can check your LINE BITMAX registered information by going to the LINE main menu and tapping the Wallet tab > LINE Pay > Settings > My info.
Note: Your LINE BITMAX account information is linked to the information registered to your LINE Pay account.
If you need to edit the information registered to your LINE Pay account, please do so from the following Help article.
Please contact PayPay for details on how to check/change your PayPay registered information.
