LINE Verification Code Account Locked? Fix It

Getting the "too many attempts" error when trying to verify your LINE account is frustrating, but it's rarely permanent. This guide is for anyone locked out of LINE's SMS verification system after repeated failed attempts, whether from mistyped codes, rapid-fire requests, or a number LINE won't accept. We'll walk you through why this happens, how to fix it step by step, and what alternatives exist when the app won't cooperate.

#Quick Answer:

• LINE locks verification temporarily, usually for 24 hours, after multiple failed attempts as a security measure.

• Stop requesting codes immediately when you see the lock  every extra try extends the timeout.

• Work through the fixes in order: restart, clear cache, update, reinstall with backup, and reboot.

• If your number is blocked, no retry will work  you'll need to use a different number to receive the code.

• For persistent locks, a temporary virtual number can bypass the problem by providing a fresh, unused phone number.

#Why LINE Locks Your Verification Code After Too Many Attempts

Here's the deal: LINE's verification system is designed to stop brute-force attacks, and your account got flagged. It's a security freeze, not a punishment  and it's reversible.

LINE automatically locks its verification system after multiple failed attempts. This happens when you request too many codes in a short window, enter incorrect codes repeatedly, or switch devices frequently. The lock is temporary—usually 24 hours—but knowing why it triggered helps you avoid repeating the mistake.

• LINE's system flags unusual activity patterns like rapid-fire code requests.

• Entering a wrong code 5+ times typically triggers a soft lock.

• Using a VOIP number that LINE's system rejects can also cause verification loops.

• The lock is account-specific, not device-specific, so switching phones won't bypass it.

• Waiting 24 hours is the standard fix, but there are workarounds covered below.

The core issue is that LINE's verification system is designed to prevent brute-force attacks. If you've been locked out, the system has flagged your account as a potential security risk. This is a protective measure, not a punishment  and it's reversible.

#LINE Verification Code: Account Locked vs. Suspended vs. Blocked  What's the Difference?

Before you panic, figure out which state you're actually in, because the next step can depend on the type of restriction you're seeing.

These terms are often used interchangeably, but they can describe different situations. A locked verification process may temporarily restrict code requests. A suspended account may mean LINE has placed the account under review. A blocked account can involve more serious account restrictions. Knowing which situation applies helps you determine whether you can troubleshoot it yourself or need to contact support.

• Locked = a temporary restriction on verification attempts that may clear after some time.

• Suspended = LINE may be reviewing the account or its activity, and additional action may be required.

• Blocked = the account may have a more serious restriction, and you may need to contact LINE support.

• Check your email, especially the address linked to LINE, for official notifications or instructions.

• If you never receive a code, it may be an SMS delivery issue rather than an account restriction.

If you're unsure which situation applies, check your email inbox for communication from LINE and review the available support options. If the problem is related to receiving SMS, troubleshoot the number, carrier, and message delivery before assuming your account is restricted.

#How to Unlock LINE Verification After Multiple Failed Tries

Stop. Right now. Don't request another code until you've read this.

If you've hit the too many attempts wall, here's the exact sequence to follow: stop trying immediately, wait at least 6–12 hours, ideally 24, then request a fresh code from a stable Wi-Fi or mobile data connection. Do not reinstall the app during the waiting period  that resets your local data and can make the lock persist longer. After the cooldown, request one code and enter it carefully on the first try.

• Stop requesting codes the moment you see too many attempts  every extra try extends the lock.

• Keep the LINE app open and connected during the cooldown window.

• Use the same network type Wi-Fi or cellular for the retry as you did originally.

• If the code arrives via SMS, type it in within 5 minutes; codes expire quickly.

• If the lock persists past 24 hours, proceed to the fixes below in order.

This step-by-step approach is the most straightforward path to recovery. Most users who follow this sequence without panicking get verification working again within a day. If it doesn't, the fixes below address the underlying technical issues.

#Restart LINE; Don't Reinstall Yet

The simplest fix is often the one people skip: fully close LINE and reopen it. On both Android and iOS, force-stop the app, not just swipe it away; wait 30 seconds, then relaunch. This clears transient session states that can interfere with the verification handshake between LINE's servers and your device.

• Force-stop on Android: Settings → Apps → LINE → Force Stop

• Force-stop on iOS: Swipe up from the bottom, hold the LINE card, and swipe it away

• Restart the app and try requesting a code again after 5 minutes

• This fixes glitches where LINE thinks you're still in a failed verification loop

• Works best when the lock is minor, under 10 failed attempts

A force-stop is more thorough than simply swiping the app away because it terminates all background processes. This gives LINE a clean slate to reconnect to its servers without any residual state from your previous failed attempts.

#Clear LINE Cache Without Losing Chats

Good news: this fix won't touch your chats, friends, or account data. It's safe.

Clearing LINE's cache removes corrupted temporary files that can interfere with verification, but it does NOT delete your chats, friends, or account data. On Android, go to Settings → Apps → LINE → Storage → Clear Cache. On iOS, you can only clear cache by offloading the app: Settings → General → iPhone Storage → LINE → Offload App, which keeps documents and data intact.

• Clearing cache is NOT the same as clearing data  never hit Clear Data or Clear Storage.

• Android users can also clear cache via LINE's internal settings: Settings → Chats → Clear Cache.

• iOS users: Offload App is the only native method; it deletes the app but keeps all data.

• After clearing, log back in  your chats will be there, and verification may work again.

• This resolves issues where corrupted cache blocks the OTP delivery mechanism.

The distinction between cache and data is critical. Clearing cache is like clearing your browser's temporary files  harmless and often helpful. Clearing data would wipe your entire LINE account from the device, which is the last thing you want.

#Update LINE to the Latest Version

Outdated LINE versions often have broken SMS verification integrations, especially after major OS updates.

Check your app store for a pending LINE update and install it. If you're on Android, also check whether auto-updates are disabled; on iOS, updates sometimes lag due to region settings. After updating, restart the app and try verification again.

• Android: Google Play Store → My Apps → LINE → Update

• iOS: App Store → Profile Icon → LINE → Update

• If no update shows, uninstall and reinstall is the nuclear option; see Fix 4

• Older versions sometimes silently fail code delivery without any error message

• Updates also fix security patches that may be triggering false positive locks

LINE frequently ships updates that address SMS verification bugs. If your app hasn't been updated in months, a known issue may be affecting your verification flow. Updating is a low-effort, high-reward fix.

#Reinstall LINE the Right Way: Backup First

This is the nuclear option  but only after you've backed up. Don't skip that part.

If restarting, clearing cache, and updating all fail, reinstalling is the next step  but only after backing up your chat history. In LINE, go to Settings → Chats → Backup & Restore → Back Up Now. This saves your chats to Google Drive or iCloud. Then uninstall, reinstall, and restore from backup. Reinstalling resets the app's local verification state, which can break a persistent lock.

• Always back up before uninstalling  otherwise you lose chat history permanently.

• Android backup goes to Google Drive; iOS uses iCloud, both free up to a point.

• After reinstall, verify with your phone number and restore your backup.

• Use the same phone number you originally registered with.

• If you don't have access to that number, skip to the alternative solutions section below.

Reinstalling is the most aggressive fix on this list, but it's also the most effective way to clear stubborn verification locks. Just remember that your phone number is the key  if you've lost access to it, no reinstall will help.

#Reboot Your Phone and Try a Fresh Code Request

Yes, have you tried turning it off and on again?  it works more often than you'd think.

A full phone reboot resets network stacks, clears RAM-resident processes, and can clear whatever stale state is blocking LINE's verification. It sounds too simple, but it frequently works  especially if you're on Android, where background SMS services can get tangled. After rebooting, wait 2 minutes for the network to reconnect fully, then open LINE and request a new code.

• A reboot also resets any VPN or proxy connections that may be blocking LINE's servers.

• If you use a VPN, disconnect it before requesting a code  LINE may flag VPN IPs.

• A reboot clears memory leaks that can cause the verification request to time out silently.

• Works well in combination with Fix 3; update  reboot after updating.

• If the code still doesn't arrive, your number may be blocked; see alternative solutions.

A reboot is a clean slate for your entire device, not just LINE. It catches edge cases the other fixes miss, which is why it's worth trying even if it seems too simple.

#LINE Verification Code Alternative Solutions When Nothing Works

If LINE's verification system won't cooperate  either because your number is blacklisted, the lock persists, or you lost access to the original number  you need an alternative approach. The most effective method is to use a different phone number to receive the OTP. A temporary virtual number from a service like SMSPin can receive LINE's verification SMS instantly, letting you complete verification without your personal SIM.

• If your number is permanently blocked, common with recycled prepaid numbers, no retry will work.

• A temporary virtual number bypasses the blocklist because it's fresh and unused.

• Check SMSPin's LINE coverage before purchasing.

• Codes arrive in real time to the virtual inbox  no SIM card needed.

• This works for both new account creation and recovering a locked account, as long as you can access the account email.

The beauty of this approach is that you're not fighting LINE's system  you're simply giving it a number it hasn't flagged. It's a workaround, not a hack, and it's completely legal for legitimate account recovery.

Still stuck after Fix 5? If your number is blocked, retrying won't help. SMSPin gives you a fresh, unused virtual number for LINE verification from $0.01 per use  with an automatic refund if no code arrives. Check LINE coverage and get verified now →

#Using an Alternative Number for LINE Verification  How It Works

Using a temporary number for LINE verification is straightforward: you rent a virtual number for a few minutes, request the code in LINE, and receive it in the service's web dashboard. The number is real and can receive SMS, but it's not tied to you personally. SMSPin charges from $0.01 per use and automatically refunds if no code arrives  so there's zero risk in trying this approach.

• Visit SMSPin's receive SMS page, pick LINE as the service, and choose your country.

• You can also check USA, UK, or India number availability at SMSPin, /uk, or /india.

• Use the provided number in LINE's verification screen and wait for the SMS.

• The code appears in your SMSPin dashboard within seconds.

• If you need a number for longer  say, ongoing verification  check SMSPin's rental options for daily or monthly rentals.

This method is especially useful if you've lost access to your original registered number. As long as you can log into your LINE account with your email or password, you can update your phone number with the new temporary one. For pricing details, see SMSPin's pricing page.

Switching phones often? Rent a virtual number for a day, a week, or a month  so LINE verification never locks you out again. Rates start at $0.01. Explore rental options →

#Preventing Future LINE Verification Locks

Once you're back in, the goal is never to see that lock screen again. The biggest triggers are rapid-fire code requests, entering codes too slowly they expire in 5 minutes, and using numbers that LINE's system flags. Keep your app updated, avoid logging in from new devices too frequently, and use a stable phone number you control long-term.

• Never request more than 3 codes in a 24-hour window unless one was clearly lost.

• Keep your LINE app updated to avoid false-positive security triggers.

• If you travel often, enable LINE's Allow logins from other devices setting for smoother re-verification.

• Link your account to an email and password so you have a non-SMS recovery path.

• For developers or testers needing frequent LINE verification, use SMSPin's API to automate number requests and OTP polling.

Prevention is always better than cure. By following these practices, you'll dramatically reduce your chances of hitting the lock screen again. And if you only need a number for testing purposes, check out SMSPin's free public testing numbers before committing to a paid plan →

Verification locks are frustrating, but they're rarely permanent. Work through the fixes in order, and if your number is the problem, swap it for a temporary one. Your LINE account  and your peace of mind  are worth the 10-minute fix.

#FAQ

Is using a temporary number for LINE verification legal or against LINE's terms?

SMSPin is not affiliated with any app or website. Please follow each app's terms and local regulations. Using a temporary number for legitimate verification  like recovering your own locked account  is generally acceptable, but using it to create multiple accounts for spam or fraud violates LINE's terms.

Why does LINE say too many attempts even though I only tried twice?

LINE counts all recent attempts across your account, not just this session. If you've requested codes on a previous day and failed, those attempts still count toward the rolling lock window. It can also trigger if LINE's system detects your IP or number as suspicious.

Should I use a one-time number or rent a number for LINE verification?

If you're verifying once to get back into your account, a one-time number from $0.01 is perfect. If you plan to switch phones repeatedly or need ongoing access, rent a number for a day or month via SMSPin's rental options  it's more reliable for repeated verifications.

What should I NOT use temporary numbers for?

Don't use temporary numbers for banking, government services, or any account that holds critical personal data. Don't use them to create multiple accounts on the same platform to bypass bans or trial limits. Legitimate use cases: testing your own apps, signing up for low-risk services, and recovering locked accounts.

Why don't I receive the LINE verification code even though my account isn't locked?

This is usually a delivery issue, not a lock. Your carrier may be blocking LINE's SMS sender ID, or your number might be on a shared sender blocklist. Try waiting 15 minutes, then request once more. If it still fails, switch to a temporary number as an alternative delivery method.

How long does a LINE verification lock actually last?

Typically 24 hours from the last failed attempt. If you keep trying, the lock resets and extends. Some users report locks persisting 72 hours for severe cases. If you've waited 48 hours and still can't verify, your number may be blocked rather than locked.
