Important: You can verify your phone number only if you're using LINE in Hong Kong, Japan, Korea, Taiwan, or Thailand.

When you request a verification code, the LINE app will send you one via text message or phone call.

These verification codes are sent out using a system designated by LINE. The phone number used may appear as either a domestic or overseas number.

If you requested the verification code:

If you received a verification code but didn't request one:
It’s possible someone entered your phone number by mistake. In this case, please disregard the text message or phone call.
Important: Even if you did not request a verification code, be sure to never share this code with anyone.
