Line Too Many Verification Attempts: How to Fix the Error and Sign In Again
You hit the "too many verification attempts" error on Line because the app's automated security system flagged your device, IP address, or phone number for suspicious activity. Line triggers this block when it detects multiple rapid requests for an OTP (one-time password) or 2FA (two-factor authentication) code within a short window. If you keep tapping resend, you lock yourself out longer.
The shortest safe path to fix this error is stopping all login attempts immediately, disconnecting from Wi-Fi to force a new IP address via mobile data, and waiting out the mandatory cooling period. If your phone number itself is flagged or blocked from receiving codes, switching to a clean, non-VoIP carrier number or utilizing reliable resources such as PVACodes for an alternative verification option gets your account back on track without risking a permanent ban.
Quick answer
The "too many verification attempts" error on Line forces a temporary lockout lasting anywhere from two hours to 24 hours. Stop requesting codes right now. Putting your phone in airplane mode for 60 seconds clears your local network cache. If the error persists after a full day, your IP address or phone number is blacklisted, requiring a network switch or a fresh number.
What Triggers the Block on Line
Line runs strict fraud-prevention algorithms designed to stop automated bots from mass-registering accounts. When you see a message stating that you have tried too many times, it means the system threshold has been breached. This usually happens during account creation, device switching, or password resets.
Most users trigger this accidentally. You might experience slow cellular data, causing the SMS containing your verification code to arrive two minutes late. Thinking the first request failed, you tap the resend button three times. Line counts every single tap as an independent security event. Once your requests cross the invisible limit, the server drops an automated rate-limit block on your connection.
Public Wi-Fi networks also cause this problem. If five other people on a coffee shop network or office router are trying to verify social or messaging accounts simultaneously, Line's security system sees that single public IP address as a bot farm. Your legitimate request gets caught in the collateral damage.
Prerequisites for Resetting Your Line Account
Before you attempt to log in again, you need to clear the slate. Trying to force your way past a security block without meeting these baseline conditions only resets the timer.
- Ensure you have a stable, non-VPN cellular data connection rather than shared public Wi-Fi.
- Make sure your phone's operating system and the Line app are updated to the latest version available in your app store.
- Keep your physical SIM card inside the primary phone slot if you are using a standard carrier-linked account.
- Stop all login attempts for at least two hours to let the automated rate-limiter cool down.
Step-by-Step Recovery Guide
If you have waited out the initial cooldown and are ready to try signing in again, follow this exact sequence to avoid tripping the security filters a second time.
- Completely close the Line app by swiping it away from your recent apps screen. Do not just minimize it.
- Toggle your phone's Airplane Mode on for 30 seconds, then turn it back off. This forces your carrier tower to assign you a fresh IP address.
- Open Line and navigate to the login screen. Enter your phone number carefully, double-checking the country code prefix.
- Tap the verification button once and put your phone down. Do not tap it again, even if nothing happens for 30 seconds.
- Wait for the SMS text message containing your authentication code to arrive. Carrier delivery times usually range from 5 to 45 seconds under normal network conditions.
- Type the code into the verification field and complete your login.
Common Places People Get Stuck and How to Tell
Knowing where you are failing helps you pivot your strategy before you ruin your chances of recovering the account. Most users run into one of three distinct roadblocks.
The first roadblock is the silent SMS drop. T-Mobile and other major carriers occasionally drop automated text messages if their spam filters flag the sending gateway. If you wait five minutes and receive nothing, do not press resend. That is a sign your carrier is blocking the sender ID.
The second roadblock is the IP shadowban. If you complete the airplane mode trick, wait four hours, and immediately get the exact same error message upon entering your number, your home internet IP or mobile IP is permanently flagged by Line's anti-abuse filter. Switching from Wi-Fi to cellular data usually solves this instantly.
The third roadblock involves VoIP number rejection. Line explicitly blocks cheap virtual phone numbers and free web-based texting services to prevent spam. If you tried registering with a public VoIP line, the app will throw repeated verification errors because it recognizes the carrier prefix as non-cellular.
Frequently Asked Questions
How long does the Line verification lockout last?
Most temporary lockouts last between two hours and 24 hours. If you continue trying to request codes while locked out, the timer automatically resets with every single tap, extending your wait time.
Can I use a VPN to bypass the too many attempts error?
Using a standard commercial VPN usually makes the problem worse. Line's security protocols flag known VPN data center IP addresses as high risk, which often triggers an instant verification block or a permanent account suspension.
Why is my SMS verification code never arriving?
Delayed or missing codes are typically caused by carrier short-code filtering, weak cell reception, or an overloaded message queue on Line's authentication servers. Moving to an area with better reception fixes most delivery issues.
Does uninstalling the Line app clear the error?
Uninstalling and reinstalling the app clears local cache files on your device, but it does not clear server-side rate limits tied to your phone number or IP address. You must still wait out the cooling period.
How can I register a new Line account if my number is banned?
If your personal phone number gets permanently flagged or restricted by Line's automated systems, you will need to use an alternative verified mobile number from a legitimate carrier or a private provider to set up a new profile.
Is there a customer support appeal process for this error?
Line does not offer live phone support or instant manual reviews for temporary verification lockouts. Automated rate limits must expire on their own before the system allows new attempts.
What type of phone numbers are supported by Line?
Line requires standard mobile numbers tied to physical SIM cards or recognized cellular providers. Virtual office numbers and free online texting tools are routinely blocked to maintain platform integrity.
If your current number continues to fail due to stubborn carrier filters or persistent rate-limiting, step back, change your network environment, and give the system a full day to reset before trying again.
