FAQs

How to contact us if you're having problems with LINE

I suddenly became unable to use a feature

Do I have to agree to the Revisions to the LINE Corporation Privacy Policy?

The error message "Unable to use account" suddenly appeared

If a screen saying "Unable to use account" suddenly appeared, please check the information for each of the three scenarios below, in order.

You haven't registered your currently contracted phone number to LINE

If the phone number you registered to LINE isn't the same as the one you are currently contracted with, you may suddenly become unable to use LINE.

Once a certain amount of time passes after canceling your phone number, it can be contracted to and used by someone else.

If the new contract holder of the phone number registers it to LINE, the LINE account it had been registered to becomes unavailable.

Checking/changing your password

Unfortunately, there is no way to directly check your registered password.

If you forgot your password, follow the steps below to change it.

Note: Be sure to write your new password down so you don’t forget it.

1. Tap the Home tab > Settings > Account.

2. Tap Password.

Note: If you're asked to unlock the screen, use the unlock method you have configured on your device, such as your passcode or biometric identification (e.g. fingerprint, face). Do not use the password registered to your LINE account.

3. Enter your new password twice, then tap Change password.

Important: Your password must contain 8-20 non-repeating half-width characters, and be a combination of at least three of the following types:

- Uppercase letters

- Lower case letters

- Numbers

- Symbols

If you're viewing this article on your smartphone, tap here to go to the Account screen.

If you don’t have access to your old device when transferring your account, see this Help article.

We recommend setting a password that is difficult for third parties to guess. For tips on setting a secure password, see this Help article.

"This message can't be displayed" appears and I can't see sent/received chat messages

If you see any of the following messages after transferring your account on a smartphone, you may not be able to view past chat messages.

- "This message can't be displayed"

- "This message wasn't backed up and restored from your previous device. Unfortunately, there's no way to read it on your current device."

- "Unable to display message as it couldn't be decrypted."

The messages above appear when:

• You transfer your account to a device with the same OS (e.g. iOS to iOS) without backing up and restoring your chats.

If you back up your chats on your old device before transferring your account, you can view them on your new device. For the steps to do so, see the following Help article.

Transferring your chat history

• You transfer your account to a device with a different OS (e.g. iOS to Android).

Note: You cannot transfer your past chats.

• You receive chat messages while transferring your account.

Any such messages cannot be transferred to your new device. For more information, see the following Help article.

About Letter Sealing

If any of these messages appear and you cannot view your past chat messages, there is unfortunately no way to re-display them. In this case, please ask the other person in the chat to send you any old messages that you need.
