My friend's account appears, but a different person is using it

If you synced LINE with your device’s contacts, your friend list on LINE will use the names registered in your device.

Note: When you open a friend's profile pop-up on LINE, the display name that they set will appear in a smaller font under their name from your contacts.

For this reason, if a phone number registered in your device's contacts was canceled or entered incorrectly, the LINE account belonging to the current owner of that phone number will appear under your friend's name in your friend list.

Please contact your friend via a method other than LINE to confirm their phone number if you are having any of the following issues.

Issues occurring on your device:

• A different account appears in your friend list under your own name

Check whether an old phone number is registered under your name in your device's contacts.

• Someone who doesn't use LINE appears in your friend list

Make sure the person's phone number is correct and current in your device's contacts list.

• The name of someone in your friend list suddenly changes

Check whether you changed their registered name in your device's contacts list.

• You meant to chat with a friend registered in your device's contacts list, but it was actually someone else

Check whether you've registered multiple phone numbers for your friend in your device's contacts.

Issues occurring on other people's devices:

• Your friend sees you on LINE even though you don't use the service

Check whether your old phone number or other information is registered in the contacts on your friend's device.

• Someone you don't know sees you on their LINE account when you register a newly contracted phone number

The previous owner of the phone number may be registered in the contacts of the device belonging to the unknown user.

• Your friend sees duplicates of your account on their LINE account

Check whether your old phone number or other information is registered under your name in the contacts on your friend's device.

If unknown users already appear in your friend list, please delete them after hiding or blocking them. For more information on removing friends, see this Help article.

If you're still having an issue after you've confirmed everything above, your device information may not be synced with the information on LINE's servers. For more information, see this Help article.

My friends don't appear

I can't add friends using ID Search

I can't add friends via QR code

Contacts on my device don't appear in my friend list

Why does a blocked or removed friend still appear in my game rankings?

I have Auto-add friends turned ON, but my contact wasn't added

I receive the message “The account you are trying to add cannot accept any more friends.”

I verified a Japanese phone number and can't search for IDs/phone numbers because age verification is required

If your LINE account is verified with a Japanese phone number, the ID/phone number search feature will be restricted until you verify that you are 18 or over. This is in order to protect minors who are using the service.

LINE uses the age verification services provided by Japanese mobile service providers. You can verify your age if you have a contract with au (KDDI), NTT Docomo, SoftBank, Y!mobile, or LINE Mobile.

In any of the following cases, you will not be able to verify your age and search for friends using their phone number or ID.

• Your contract is with a mobile service provider that cannot be used for age verification.

• Your mobile service contract is under the name of someone under 18 years of age.

• Your mobile service contract is under a company's name.

• You have not registered your user information. (For mobile service providers other than LINE Mobile)

• You have not applied for sp-mode. (For NTT Docomo)

• You cannot configure your mobile service provider's setting for sharing your age. (For mobile service providers other than LINE Mobile)

In any of the situations mentioned above, try adding friends with a different method (e.g. QR code scan or auto-adding friends from your device contacts).

If you haven't finished registering your user information or configuring the setting for sharing your age, please contact your mobile service provider for assistance.

In the case that you cannot verify your age even though you are 18 or older, have registered your user information, and configured the setting to share your age, contact us via this Inquiry Form.
