You transferred your LINE account using a phone number from a different country
When you transfer your LINE account (using your registered email address or the Facebook account it is linked with), use of your LINE Pay account will be restricted if you verify your LINE account with a phone number from a country different from the one it was previously verified with. This is in order to protect your account's payment information. If your LINE Pay account is restricted, you can delete it yourself, or use your existing LINE Pay account again.

• Deleting your LINE Pay account
When you tap Reset Account from the lockout screen, all of the information from the LINE Pay account you had been using until now will be deleted, and you can register again.

• Using the LINE Pay account you had been using again
Reinstall the LINE app, then use the phone number you had been using for verification again when you log in. After verifying your account, you can use the LINE Pay account you had been using again by going to More > LINE Pay from the LINE app.

• If you cannot reset your account and are having issues using it
Please contact us again after referring to this page.

Can I continue using LINE Pay after changing to a new device? toggle
Yes. As long as you have registered your email address with LINE, you can continue using LINE Pay even after switching to a new smartphone. 

When you install LINE on your new smartphone, select "LINE User Login" and log in with the email address you registered to continue using LINE. Your LINE Pay and OSA accounts will be linked automatically. 

However, you cannot use LINE Pay in the following cases:
1. If you carry over your account to an unsupported OS (all OSes other than iOS and Android, such as BlackBerry, Nokia, and Windows Phone)
2. If you carry over your LINE account using a phone number with a different country code

In these cases, please delete your LINE Pay account before switching to a new phone. If your OSA has any remaining balance, please withdraw it. If you have deleted your LINE Pay account without fully withdrawing your remaining balance, you can still withdraw the remaining balance at the counter of any Cathay Bank branch. 

Please see here for more details about how to delete your LINE Pay account.

My card information could not be confirmed toggle
If you set a CTBC or Taishin Bank card as your main card for making credit card/My Code payments with LINE Pay, a check will be performed to make sure your phone number registered with LINE and your credit card registered with LINE Pay match the information registered with the bank that issued the card.

This check is also performed if use of your LINE Pay account has been restricted due to the Terms and Conditions of Use being violated. This is in order to ensure secure transactions. If your information matches, the restriction on your account will be lifted. However, if the information does not match and the restriction on your account is not lifted, you will not be able to use LINE Pay.

If the restriction on your account cannot be lifted, please try using LINE Pay again after changing the phone number registered with your bank.

Important:
- CTBC or Taishin Bank family cards cannot be used.
- If you change your debit card information, it can take 1 to 2 business days for the changes to take effect.
