This Help article covers methods and examples of LINE account-stealing scams, as well as what to do when your account has been compromised.
Attention
Any attempts to ask for your LINE registered information (phone number, email address, password) or verification code, or for you to enter it on a screen, are all scams. Your LINE registered information will not be used for any purpose other than transferring your LINE account yourself.
Topics covered
Methods and examples of LINE account-stealing scams:
This section covers specific examples of ways accounts are stolen, as well as sample messages or texts that are used in these scams. All of the following messages are scams. If you receive any of the following kinds of messages, do not respond to them.
Message content and examples
• Messages saying, "Your account has been restricted (or your LINE data has disappeared). Log in from the link below to help us lift the restriction on your account."
Accessing the links in these types of messages will redirect you to a fake LINE login screen. LINE does not use these types of methods to lift restrictions on accounts (due to violating our Terms of Use), or to restore lost data.
• Messages from someone pretending to be a delivery person, saying things like "You need to reschedule a delivery," "Delivery address unknown," or "Your package was kept on hold," trying to get you to access a URL.
Accessing the URLs in these messages may result in the installation of malicious apps or files, or redirect you to phishing sites posing as delivery services, potentially allowing remote access to your text messages. This unauthorized access poses the risk of third parties using your text messages to verify your phone number and create a LINE account without your consent.
• Messages impersonating a friend through LINE or social media, asking you for your phone number or verification code.
• A message urging you to take an online poll, saying something like, "Can you vote for my pet?"
Messages urging you to participate in an online poll, such as to vote for someone's pet, will lead you to a screen that prompts you to enter information such as your phone number and password registered with LINE.
• LINE-related phishing emails
Phishing scams are evolving with each passing day. Recently, there have been reports of scams that use threatening messages like "Your LINE account will be suspended if you do not verify your account again within 48 hours," to prompt users to tap on links in an attempt to steal their LINE account information.
Please keep the following important points in mind.
- Check the sender's email domain
The official email address used by LINE is "xxxx@line.me". Be cautious of any emails coming from domains other than "line.me".
- Pay attention to the email content
LINE will never suddenly ask users to verify their accounts again via email unless they have initiated the request themselves, such as for account transfers or when contacting LINE.
- Look for any unusual characters in the link address
The link in the email directing you to verify your account again might contain suspicious characters, such as those enclosed in square brackets or full-width alphabets. In such cases, do not tap on the link under any circumstances.
How a LINE account can be stolen:
Many unauthorized logins (thefts) of LINE accounts occur due to actions such as those mentioned below.
Your account can be stolen if you:
• Shared your phone number registered to LINE and verification code with a third party (including a friend or family member).
• Entered your phone number and verification code on a screen other than the one for transferring your LINE account.
Malicious acts of getting you to enter your LINE registered information (phone number, email address, password) or verification code into a fraudulent screen to steal your LINE account are called phishing. Phishing scams use various tactics, such as pretending to be one of your contacts or a company, or sending messages that create anxiety about your LINE account's security being compromised.
If you received a message like the ones above, do not open any links within the message or enter your email address and password on any login screen that appears after accessing a link. Even if you accidentally logged in, DO NOT enter the verification code under any circumstances.
What to do if you accidentally logged in on a phishing site:
If you accidentally logged in on a phishing site:
1. Change your LINE password.
2. Change your password for other companies' services.
Important: If you’re using the same password you registered on LINE with other companies' services, immediately change those passwords, as it’s possible the scammers will attempt to log in to those accounts as well.
3. Contact LINE.
Note: If you come across any suspicious emails or messages claiming to be from LINE, please report them.
Actions to take if your LINE account might have been stolen:
If it's possible your LINE account was stolen, see the following Help article.
My LINE account was or may have been stolen
Things that may occur if your LINE account is stolen:
When your LINE account is stolen, your family members and friends may experience the following issues.
• Your family and friends may be sent messages asking them to buy prepaid cards or WebMoney cards/tickets.
• Your email address and password registered to LINE changes.
• Money is withdrawn from a bank account linked to your LINE Pay account.
If you've been victimized, please contact the police immediately.

Letter Sealing is an encryption technology that prevents any non-members of a chat on LINE, including us, from seeing the contents of its messages.
Useful info
For information about the difference between main and sub devices, see Using the same LINE account on more than one device.
Topics covered
- About Letter Sealing
- Information Letter Sealing is applied to
- Confirming if Letter Sealing is enabled
- Verifying your identity on sub devices
About Letter Sealing:
Letter Sealing uses a technology called end-to-end encryption.
End-to-end encryption is a communication method that makes it so that only the sender and receiver of a message can decrypt its content. Message content is saved in an encrypted state on the server, as well. When both the sender and receiver of a message have Letter Sealing turned on, the message can be sent and received with greater security using this feature.
Letter Sealing is currently turned on by default so users can exchange messages in chats more securely and safely.
Information Letter Sealing is applied to:
Letter Sealing encrypts the following information sent as messages.
• Text messages (not including messages sent through other services like YouTube)
• Location information
• Photos/Videos/Voice messages
• Files
• Voice/video calls in 1-on-1 chats
While client-server transport layer encryption is applied, Letter Sealing isn't applied to the following.
• Voice/video calls in group chats
• Meetings
• Albums
• Notes
Be advised
- Photos, videos, voice messages, and files may not be encrypted depending on your version of LINE and specifications.
- There is no option for disabling Letter Sealing as it is a means of enhancing security and protection on LINE.
- After transferring your LINE account, Letter Sealing may prevent you from viewing messages sent and received in the past. In this case, refer to "This message can't be displayed" appears and I can't see chat messages.
Confirming if Letter Sealing is enabled:
To verify whether Letter Sealing is enabled, follow the steps below and if key fingerprints are visible, it indicates that the feature is active.
Useful info
Key fingerprints are unique encryption keys that Letter Sealing gives to each user so they can send messages to one another safely and securely. The actual keys are kept secret and will not appear in LINE chats. If the key fingerprints you and your friend see match, it means your messages are securely encrypted.
1. Tap
at the top of the chat.
2. Tap This chat is protected with Letter Sealing at the bottom of the screen.
Note: This won't appear if Letter Sealing is turned off. To enable it, open the LINE app on your main device, tap the Home tab >
> Privacy > and turn ON Letter Sealing.
3. Compare the key fingerprints on your device and your friend's device.
Note: To compare key fingerprints with your friend, we recommend meeting face-to-face or using a form of communication you trust.
Verifying your identity on sub devices:
If you use LINE on a sub device after turning on Letter Sealing, you'll be required to verify your identity the first time you send a message by entering a verification code on LINE on your main device.
If you do not see the verification code entry screen on LINE on your main device, verify your identity again with the steps below.
Note: To send messages with LINE on your sub device with Letter Sealing turned on in LINE on your main device, you need to verify your identity.
1. Restart LINE on your main device.
2. Log in to LINE on your sub device.
3. Open a chat from
on the main menu.
4. Select Verify my identity and get a verification code.
5. Enter the verification code shown on your sub device on the identity verification screen that appears in LINE on your main device.

• You haven't registered your currently contracted phone number to LINE
• You entered and verified the same phone number with LINE on another device
• Someone else entered your information (e.g. verification code, phone number, password, account transfer code) on another device
You haven't registered your currently contracted phone number to LINE:
If the phone number you registered to LINE isn't the same as your current phone number (e.g. you canceled your previous phone number and got a new one) you may suddenly be logged out of LINE.
Once a certain amount of time passes after canceling your phone number, someone else can receive a contract for it and use it.
With LINE, the same phone number cannot be registered to multiple LINE accounts. If the new owner of the phone number registers it to LINE, the LINE account previously registered with that number becomes unavailable.

Important: Make sure your current phone number is registered to LINE
The other person cannot steal your account or access your LINE data (such as your friends or chat history).
To prevent the same situation from occurring in the future, be sure to register your latest phone number to LINE if it changes.
As there is no way to transfer your previous LINE account, we ask that you create a new LINE account with your current phone number.
Depending on the results of our investigation, we may be able to transfer some paid items from your previous account to your new account. If you'd like us to look into your paid items, please contact us via the Inquiry Form.
The following data can be transferred:
- Stickers, themes, and emoji (including those received as gifts)
- Your purchase history of paid items, along with your Coin and LINE Point balances
- Your Credit balance added on LINE STORE

Be advised- We only accept inquiries from the owner of the LINE account that's experiencing the issue.
- In principle, we do not accept inquiries made on behalf of family members, friends, or acquaintances.
- For questions that require you to fill in certain information or details about a situation, make sure that you provide complete and accurate information relevant to your situation.

You entered and verified the same phone number with LINE on another device:
The same phone number being registered to (verified with) more than one LINE account is causing the issue. With LINE, you can only register (verify) one LINE account with one mobile phone number. If you register (verify) a different LINE account using a phone number that is already registered to another LINE account, your previous LINE account will be automatically deleted.
Since there is no way to transfer your previous account, please continue using the account you currently have access to, or create a new one.
