Getting an error when verifying a phone number:
If you do anything that violates our Terms and Conditions of Use or if you repeatedly have a verification code issued, your use of LINE will be restricted and you'll see an error message based on your situation.
Be advised
If you see the "Please wait XX day(s) then try again" or "Invalid phone number" error messages, please wait until the restriction is lifted. Even if you contact us without waiting for the restriction to be lifted, we will reply to you with the same information in this Help article.
"Verification is temporarily blocked. Please wait XX day(s) then try again" appears
Due to violating our Terms, verification will be restricted for a specified period of time. Please try verifying your phone number again the day after the specified period of time.
Please refrain from any acts that violate our Terms when using LINE in the future. Below are the main standards for what are considered violations.
• Posting content that is generally considered unacceptable, such as abusive language or obscene content.
• Exchanging personal information (e.g. phone number, address, LINE ID), or continually inviting or soliciting others to meet in person.
• Engaging in any unlawful transactions, such as the illegal trading of banned substances, stocks, etc.
• Acts of planning or inviting minors to inappropriate meetings or assemblies.
For more details, see the
Standards regarding posts on LINE on the LINE Safety Center website. For security reasons, we cannot directly provide you with detailed information such as the reason for your current violation.
"Invalid phone number" appears
If you see an error message saying "Invalid phone number" when entering your phone number, you may have received a temporary restriction for repeatedly having a verification code issued. Try again one to two days after the error appeared.
Not receiving the verification code on the phone number you entered:
Be advised
Check if the phone number you currently have a contract with was entered correctly. You will not receive the verification text message if your phone number is entered incorrectly. Landline phone numbers cannot be used.
If you still don't receive the text message despite entering the correct phone number, see the following information.
Check if your contract allows you to receive text messages
If you're using an MVNO, it's possible the plan you're contracted with doesn't let you receive text messages. Check if your mobile plan lets you receive text messages or go to your settings page on your mobile service provider's website or contact their customer support.
If you can't receive text messages, try selecting Call me instead to verify your phone number. If you can't use text messages or verify your phone number with the Call me instead option, you will not be able to sign up for a LINE account.
Try the Call me instead option
If you're not receiving the verification code via text message, you can get one via the automated on-call guidance.
To use the Call me instead option:
1. Tap Call me instead at the bottom of the verification code input screen.
2. Answer the call you receive on the phone number you entered.
3. Enter the verification code you received via the automated on-call guidance.
Useful info
