Recover Line Account: Full Step-by-Step Guide

If you’ve been locked out of your Line account, you can recover it using your registered email, phone number, or Facebook account, as long as you still have access to the associated credentials. This guide walks you through every official recovery method, what to do if you’ve lost your phone number, and how to prevent permanent data loss.

Why Line Accounts Get Locked or Lost

Line is a messaging app widely used in Japan, Taiwan, Thailand, and other parts of Asia. Unlike some apps that only require a username, Line ties your account to a phone number and email. You can lose access for several common reasons:

• Switched phones without transferring the account properly.
• Deleted the app and forgot to set up a password or linked email.
• Changed phone numbers and didn’t update Line before canceling the old SIM.
• Forgot your password and no longer have access to the recovery email.
• Account temporarily suspended due to suspicious activity or a violation of Line’s terms.

Understanding which situation applies to you determines the fastest path to recovery.

Before You Start: What You’ll Need

Line’s recovery process requires you to prove you own the account. Gather the following before attempting any method:

• The phone number or email address you originally registered with.
• Access to that email inbox or phone number for verification codes.
• If you linked Facebook, your Facebook login credentials.
• Your Line password (if you remember it).
• Any previous device that still has Line logged in (helps for verification).

If you have none of these, recovery becomes significantly harder—but not always impossible. See the “No Access to Phone or Email” section below.

Method 1: Recover Using Email and Password

The most straightforward recovery works if you previously set an email and password in Line’s settings. Here’s the exact process:

1. Open the Line app on your new or current phone.
2. Tap Login (or Log in on the welcome screen).
3. Choose Email account as the login method.
4. Enter the email address and password you used for Line.
5. If prompted, enter the verification code sent to your phone or email.
6. You’re in. Your chat history and friends should sync automatically if you had a backup enabled.

If you don’t remember your password, tap Forgot password? on the login screen. Line will send a reset link to your registered email. Follow that link to create a new password, then log in.

Method 2: Recover Using Phone Number

If you never set an email (or don’t remember it), phone number recovery is the next option. This works only if your phone number is still active and you can receive SMS.

1. Open Line and tap Login.
2. Choose Phone number.
3. Enter your country code and full phone number.
4. Line sends a 4-digit verification code via SMS.
5. Enter the code in the app.
6. Line will then ask if you want to restore chat history from a backup (if you have one) or start fresh.

Important: If you previously had Line on an old phone and never deleted the account, logging in with the same phone number on a new device will automatically deactivate the old session. Your friends and groups remain, but your chat history may be lost unless you had a backup.

Method 3: Recover via Facebook Login

If you linked your Facebook account to Line, you can use it as a recovery path. This is useful when you’ve lost both email and phone access.

1. On the Line login screen, tap Facebook.
2. You’ll be redirected to Facebook’s login page.
3. Enter your Facebook credentials and authorize Line.
4. Line will log you into the account linked to that Facebook profile.

Note: This only works if you originally linked Facebook in Line’s settings (Settings > Account > Link Facebook). If you never linked it, this method won’t find your account.

What to Do If You Lost Your Phone Number or Email

This is the hardest scenario. If your phone number is no longer active (e.g., you canceled the SIM) and you don’t have the email either, Line’s official support is your only option. Here’s how to approach it:

1. Go to Line’s official help center (help.line.me) from a web browser.
2. Search for “account recovery” or “lost phone number.”
3. Use the Contact Us form to submit a request.
4. Provide as much proof as possible: your registered name, profile picture, friends’ names, and any purchase receipts from Line stickers or themes.
5. Wait for a response (usually 1–3 business days).

Line’s support team will ask you to verify ownership. Without any original credentials, recovery is not guaranteed—this is why it’s critical to keep your email and phone number up to date in your Line settings.

How to Prevent Future Lockouts

Once you’re back in, take five minutes to secure your account so this doesn’t happen again:

• Set an email and password in Settings > Account.
• Link Facebook as a backup login method.
• Enable two-factor authentication (Settings > Account > Two-step verification).
• Back up your chat history to iCloud or Google Drive (Settings > Chats > Backup).
• Update your phone number immediately if you change SIMs.

These steps take less than five minutes and can save you from losing years of messages and contacts.

Frequently Asked Questions

Can I recover a Line account without a phone number or email?

Only through Line’s customer support, and success depends on how much proof you can provide. If you can name friends, show purchase receipts, or provide the exact registration date, your chances improve. But without any credential, Line may not be able to verify ownership.

Will I lose my chat history if I reinstall Line?

Yes, unless you have a backup. Line’s default behavior is to store chat history locally on your device. If you uninstall without backing up to iCloud/Google Drive, your messages are gone. Always back up before deleting the app.

What if my account was suspended?

Line suspends accounts for violations like spam or using unofficial modified versions. You can appeal through the help center, but if the suspension was for a serious violation, it may be permanent. Don’t use third-party Line clones (like LINE MOD) if you want to keep your account.

Can I recover a Line account if I changed my phone number?

Yes, if you updated your number in Line’s settings before the change. If you didn’t, you’ll need to use your email or Facebook login. If you have neither, contact support with proof of your old number (e.g., a bill with your name).

How long does Line support take to respond?

Typically 1–3 business days, but during peak times it can take a week. Check your spam folder for replies. Be patient and provide all requested information in your first message to avoid back-and-forth delays.

Is it safe to use third-party recovery tools?

No. Any website or app that promises to “hack” or “recover” your Line password is a scam. They will steal your personal data or install malware. Only use official Line methods or the official help center.
