# Flow when receiving a LINE notification message

Use of optional functions requires an application

Only corporate users who have submitted the required applications can use the functions described in this document. To use it with your LINE Official Account, contact your sales representative or contact our Sales partners (opens new window).

In addition to agreeing to get LINE notification messages, users must authenticate their phone number by SMS (SMS verification) once every 180 days to get LINE notification messages.

User flow when receiving LINE notification messages

Settings for getting LINE notification messages are comprehensive

Once a user agrees to get LINE notification messages, they're considered to have agreed to get LINE notification messages from all LINE Official Accounts.

For example, if a user who has agreed to get LINE notification messages in response to a LINE notification message sent from LINE Official Account A also gets a LINE notification message sent from a different LINE Official Account B, the user will have agreed to get LINE notification messages and won't need to give consent again.

SMS authentication must be done once every 180 days for each user's LINE account

Once a user performs SMS authentication, SMS authentication isn't required when getting LINE notification messages sent from all LINE Official Accounts for 180 days.

For example, if a user who has performed SMS authentication in response to a LINE notification message sent from LINE Official Account A gets a LINE notification message sent from another LINE Official Account B within 180 days, the user will have already been SMS authenticated and won't be required to perform SMS authentication again.

Cases where SMS authentication isn't required

SMS authentication isn't required when getting a LINE notification message in these cases:

  • Within 180 days of creating a new LINE account
  • Within 180 days of changing the phone number registered to your LINE account.
