If an error message appears during the verification process, try restarting the app and your device. Staying on the verification screen for too long can cause an error message to appear when you try to proceed.
You may also be able to resolve the issue by checking the steps to create a new account in this Help article.
If the error message still appears after trying the suggestions above, contact us via the Inquiry Form.
You can only verify a phone number that can receive text messages or phone calls.
Landline phone numbers, numbers that start with 050, and virtual phone numbers cannot be used for verification, so be sure to use a phone number offered by a mobile service provider.
Note: If you verify a phone number that is already registered to another LINE account, the old account will be deleted.
For the steps to change your registered phone number on LINE to a number from a different country, see this Help article.
If the phone number you use for verification has been registered to a LINE account before, the name registered to that account will appear. This lets you make sure the LINE account is yours before transferring it.
If the LINE account that appears isn't yours, please tap No, that's not me.
New LINE accounts can no longer be created by verifying a Facebook account as of March 31, 2020.
The only way to create a new LINE account is by verifying your phone number (via text message).
You can still use a linked Facebook account as a verification method when transferring your LINE account.
When transferring your account to a new device, please keep your old device on hand because you will need the verification code sent to it. To ensure your account is transferred safely, you must register your phone number, password, and email address beforehand.
If your account is not successfully transferred, your friends, groups, and other data will be deleted.
Note: For more information about your friends and groups disappearing after transferring your account, see this Help article.
Even if your account data is lost, we may be able to transfer your purchased stickers and some other types of paid items if you contact us. To do so, please create a LINE account and send an inquiry from the following link:
An error message will appear if you repeatedly request an account transfer code in a short amount of time.
If the message "You have been temporarily restricted from requesting account transfer codes because you repeatedly requested them. Please try again later." appears when requesting a code, try again after 24 hours has passed.
If your friends and groups disappear after transferring your account, it means that you did one of the following:
• Created a new account
• Transferred a different account by mistake
In either of the above cases, the account that you had been using before will become inaccessible, and your data (including your friends and groups) will be deleted and cannot be restored.
Note: The same phone number and Facebook account cannot be registered to multiple LINE accounts. Registering a phone number to a different LINE account will make the account that the phone number was registered to before inaccessible.
Even if your old account data is lost, you can still continue using your purchased items, LINE Pay balance, LINE POINTS, and other billing information. For the steps to redownload your purchased items, see this Help article.
Your password setup code will be sent in a chat message to the LINE account you're trying to transfer. Please start LINE on your previous device and check the password setup code in the message you received.
Note: If you're using the LINE account you want to transfer on LINE for PC or iPad in addition to your smartphone, you can also check for the chat message there.
If you can't confirm the password setup code, there will be no way to transfer your LINE account. In this case, please sign up for a new account.
The way you can continue transferring your account depends on your situation.

A phone number, email address, or Facebook account cannot be registered to more than one LINE account at the same time. When you register the same information to a new account, it is removed from the account it was previously used with.
A LINE account needs to be registered with a phone number or Facebook account at all times. If an account is no longer linked with either of these after information has been removed, it will become inaccessible.
Note: When an account becomes inaccessible, its friends, chats, and other data is deleted and cannot be recovered.
Take care not to use the same information registered to an account you're currently using if you make an account on another device. If you want to create multiple LINE accounts, you need to register them with different information and use them on separate devices.
Note: Only one LINE account is meant to be used per device.
All of LINE's basic features can be used for free.
Note: Some items, such as Coins and Stickers, must be purchased to use in LINE.
Please understand that you will need to pay for any data usage fees that you may be charged depending on the data plan you have with your mobile phone carrier. You may be charged every time you connect to the service if you are paying for only the amount of data you use. For this reason, we recommend signing up for a flat-rate data plan if you don't already have one.
All of LINE's features can be used for free, even when you're overseas.
Also, there are no fees for using LINE with someone who lives in another country.
Please understand, however, that you will need to pay for any data usage fees incurred, even when using the app overseas. These fees will depend on the data plan you have with your mobile service provider, but international data usage fees may differ from your regular plan, so make sure to check your mobile contract or inquire with your mobile service provider for details.

If you want to update or install the LINE app, download the latest APK file here.

We're asking users to agree to updates regarding the usage of their personal information and our Privacy Policy. These updates will help improve the level of service provided to LINE users.
For more information on the changes to both our Privacy Policy and the usage of your information, please refer to the following links:
We'll keep doing everything we can to provide the most convenient and secure experience possible with LINE, and will continue making improvements based on user feedback.
When collecting URL access information, we take the following measures to protect users' privacy:
• Only the domain name and the hashed variable part of the URL (path and parameters) is collected.
• Collected data is not linked to a user identifier.
It is very difficult to obtain an original URL from its hash, so we calculate our access ranking by hashing the URLs of widely used public sites and comparing the resulting hashes with the URL hashes we collected. We then calculate the number of site visits only for the sites with matching hashes.
We do not try to convert hashed URLs to the original URLs in any way.
When your friends on LINE use external apps (e.g. apps offered by companies other than LINE), those apps ask LINE whether it can access your profile information. The External app access setting lets you allow or deny such access.
Note: Your profile information includes your LINE display name, profile photo, status message, and uniquely assigned internal identifier (a unique number that LINE gives each user).
If you enable this setting, external apps will be able to access your LINE profile information, which is used in the friend requests and display of names in rankings for those apps.
For your reference, LINE Games and other LINE services can access your profile information regardless of your External app access setting.
Please see here for more information about our privacy policy.
This includes which friends were in the chat room, the date and time of sent/received messages, "Read" marks, data formats used, and information on the use of features (such as the use of the "unsend" feature and accessed URLs).
Please be assured that the content of your chat messages (including images and videos) and calls will NOT be used.
Chats with official accounts
This means communication in chat rooms, including chat content (text messages, images, and videos). However, the content of chats with accounts used for industries which are deemed by LINE as having a high possibility of containing sensitive information (personal information or other information of a private nature) will be exempt. This includes industries such as financial and political institutions, state institutions, and hospitals.
LINE VOOM
This includes the content, date, and time of posts, data formats used, stickers posted in comments, time viewed, and number of times viewed. However, LINE VOOM posts set to “Only me” will be excluded.
Use of the app, including LINE's in-app browser, save feature, and sharing
If the features for saving and sharing data are used, information including the data formats and when the data was viewed will be acquired.
Website browsing information
This includes information pertaining to URLs you have viewed and the source information of the URLs accessed via the LINE app.
We aim to use the above mentioned information to bring all of our users an even better experience when using LINE’s services. For more information, see here.
Agreeing to the updated policies regarding the use of your information will allow LINE to offer further service improvements for all users. We appreciate your cooperation in agreeing to these changes.
When you agree to share your information, we can make improvements to our services in the following ways:
Prevent abuse and other fraudulent use of LINE services and features
This includes improving countermeasures against harmful activity such as harassment, spam, and account theft.
Improve services through continued research and development
This includes improving our AI services and creating more user-friendly screen layouts and designs.

By consenting to sharing your data, you can see content and ads that you're personally interested in.
The LINE Privacy Policy has been revised in accordance with the amended Japanese Act on the Protection of Personal Information, which is scheduled to go into effect in April 2022.
To continue using LINE in the future, you will need to agree to the Revisions to the LINE Corporation Privacy Policy.
A notice about these revisions will be displayed in the LINE app. Even if you choose not to agree, this notice will appear again after a certain amount of time. If you don't agree to the revised Privacy Policy, you'll see this notice every time you start LINE from March 28.

If your LINE account was stolen by someone logging in without your authorization, please contact us with the details using the Inquiry Form. We will delete the account to prevent any further unauthorized use.
If you had any items, we can restore them after confirming they were on your old account.
The following can be restored:
• The right to use your paid items, such as LINE stickers and themes (including those received as gifts) • Your purchase history and Coin balance • Your Credit purchased on LINE STORE
There have been many cases where unauthorized third parties have logged in to internet services using email addresses and passwords leaked from other services. Please note that no information registered to LINE, such as phone numbers, email addresses, and passwords, have been compromised.
If you are using the same email address and password for LINE as another service, we strongly recommend changing your password.
The following types of messages are often sent by a third party when an account is stolen. If you receive messages asking you to do any of the following from a friend, it is possible their account may have been stolen:
• Help me buy prepaid cards
• Help me buy iTunes cards
• I’m in trouble and need you to transfer money to my bank account
As they may change the content of their messages at any time, you should also suspect if your friend’s account has been stolen in the following cases:
• The messages don't sound like the way your friend talks
• A friend whom you have not spoken to for a long time suddenly asks you for money
• The friend's language is unnatural
Your friend’s account was stolen
If you suspect that your friend’s account may have been stolen, please contact them outside of LINE (in person, by text, by phone, or on a social network) to let them know.
Your account was stolen
If you are suddenly unable to access your account even though you did not make any changes to it, or if your friend contacts you to let you know that your account has been stolen, please see the following article:
