Conditions for using phone number verification:
When you register or change your phone number on LINE, you need a phone contract and a device that can receive text messages or voice calls to receive and confirm the verification code via text message or voice call.
Note: Landlines and virtual phone numbers can't be used.
Be advised
You will not be able to verify a phone number if you can't receive the verification code text message, such as when:
• Your device is broken or lost.
• You don't have a contract for a phone number.
• You're using a data SIM with a contract for a mobile service provider other than LINE MOBILE.
Also, for security reasons, we cannot send you a verification code directly via other means, such as email. Try verifying your phone number again after contacting your mobile service provider and changing your plan or getting a phone number and device that can receive text messages.
Details about issues and how to solve them:
See the following information based on the issue you're having.
- I see a message saying "Invalid phone number"

You cannot register landline or virtual phone numbers to LINE.
Please try to verify a phone number again with one from a mobile service provider in Hong Kong, Japan, Korea, Taiwan, or Thailand that can receive text messages.
Note: If you verify a phone number that is already registered to another LINE account, your previous account may become inaccessible.
The country/region you selected when verifying your phone number is different than the entered phone number's actual country/region
To verify your phone number, you need to select the correct country/region for the one you enter from the top of the phone number entry field.
Tap the down arrow next to the country/region name shown above the phone number field, select the correct country/region for your phone number, then try to verify your phone number again.
You saved your phone number as a phrase in Text Replacement on an iOS device

Check if your mobile plan allows you to receive text messages by visiting your mobile service provider's website and checking your settings page, or by contacting their customer support.
You've blocked calls from phone numbers in other countries or unknown phone numbers
Verification codes are sent using a system designated by LINE. The phone number used may appear as either a domestic or overseas number.
For this reason, if you're blocking calls from phone numbers in other countries or unknown phone numbers, you may not be able to receive the verification code.
The problem persists after checking the above solutions:
If you've checked all of the above information but still don't receive the verification code text message and are unable to verify via the Call me instead option, you will not be able to verify your phone number on LINE.
Note: For security reasons, we cannot send you a verification code directly via other means, such as email.
Additionally, if you're not receiving the verification code despite having no issues with your text messaging settings, the issue may be caused by your usage environment or the text messaging feature itself.
If the issue is caused by your usage environment or the text messaging feature, we will not be able to investigate it in detail or provide assistance. Please contact your contracted mobile service provider or device manufacturer, or try verifying a different phone number.
FAQ:
Q: What happens if I entered my phone number incorrectly?
A: If you entered your phone number incorrectly, the verification code may have been sent to the person using the phone number you mistakenly entered. In this case, close and restart the app, then proceed through the steps to verify your phone number again.
Note: If someone receives your verification code unintentionally, they will not be able to misuse it to perform unauthorized actions, such as stealing your LINE account.

If your chat history auto-backup fails
If a chat history auto-backup fails because you don't have enough free space in Google Drive or on your device, you'll see one of the following error messages as a notification or on the settings screen.Note: You will not receive a notification if an auto-backup fails for another reason.
• Backup failed at XX:XX on MM/DD.
Not enough free space on Google Drive.
• Backup failed at XX:XX on MM/DD.
Not enough free space on your device.
If you receive either of the above notifications, make sure you have enough free space on your device and Google Drive, then try to back up your chat history again.
Solutions to try if the issue persists
If the issue persists after you've configured the above settings:
• Try backing up your chat history multiple times.
• Update your OS to the latest version.
• Update LINE to the latest version.
• Restart your device.
• Delete unnecessary data from iCloud or Google Drive, as well as your smartphone (or SD card or other storage).
• Turn your 4G/5G/Wi-Fi off and on again.
What to do if the issue persists after trying all of the above solutions
• Set a backup PIN.
If you're unable to proceed with backing up your chat history to iCloud Drive or Google Drive, you can restore the last 14 days of your chat history (text messages only) by setting up a backup PIN.
• Use Premium Backup.
Note: Premium Backup is only available to LYP Premium (Japan) or LINE Premium (Thailand) members.
You can back up and restore photos, videos, files, and voice messages shared in chats, regardless of the OS you're using (e.g. Android, iOS). For details, see About Premium Backup.
My chats were restored, but the photos and videos weren't:
Photos and videos sent in chats cannot be backed up or restored with Standard Backup.
Note: If you use Premium Backup, you can restore photos, videos, files, and voice messages shared in chats. This feature is only available to LYP Premium (Japan) and LINE Premium (Thailand) members.
If you transferred your LINE account and restored your chat history from a backup, the photos/videos in your chats and in Photos & videos, from
at the top of a chat, will be shown as or .If you have photos or videos you wish to save, please save them to your device before transferring your account.
I can only restore some of my chat history:
To restore your entire chat history when transferring your LINE account using Standard Backup, you need to restore it from backup data saved to iCloud Drive or Google Drive.
Setting a backup PIN beforehand or transferring your account with an easy transfer QR code will only transfer the last 14 days of your chat history.
If you want to restore earlier chat history, you need to back it up to iCloud Drive or Google Drive from within the LINE app beforehand, and then restore your chat history when transferring your LINE account. However, if you transferred your LINE account to a different OS (such as from Android to iOS or vice versa), you won't be able to restore your chat history using this method.
On iOS, you may be able to restore your chat history by reinstalling the app after transferring your LINE account and then attempting the transfer again. On Android, you can restore your chat history even after transferring your LINE account. For details, see the following Help article.
