I got a message from a company's official account that I didn't add as a friend toggle
You may get notification messages from the official accounts of companies. These are messages for telling you things like package delivery dates and when monthly bills are due.

The name of an official company account has a gray, blue, or green icon next to it. To make sure that a notification message is from an official account, check to make sure it has an icon with one of these colors.

Notification messages let you receive helpful information without having to add the official accounts of individual companies.
Note: This feature is turned on when you tap Agree on the "Regarding Usage of Your Information" screen. You can turn it off separately in your settings.

Only notification messages that we have determined to be valid and appropriate are sent out to users, and messages will not be sent for the purpose of advertising.

How notification messages work
First, a company sends a message transmission request to LINE's servers based on a customer's phone number. A notification message is then sent to the account of the LINE user with that phone number registered.

The phone number sent from the company is hashed, and the information that LINE Corporation receives is only used for the purpose of verifying the message recipient, after which it is promptly deleted.

There may be times when we need to verify your identity via text message before we can send a notification or in order to confirm notification content which includes your personal information.

Requirements for sending notification messages
Notification messages are sent when they meet the three requirements below:
• The phone number sent from the company matches one registered to an existing LINE account.
• The LINE account has the Receive notification messages setting turned ON.
• The LINE account has not blocked the official account of the company sending the notification message.

About Letter Sealing toggle
Letter Sealing is a feature that provides end-to-end encryption (E2EE) for chat messages. E2EE is a communication system designed so that messages saved on our servers are encrypted and cannot be read by anyone except the sender and receiver of the message.

Once the sender and receiver have both turned on Letter Sealing, they will be able to start sending messages with added security.

The following information will be encrypted:

• Text messages (not including messages sent through other services like YouTube)
• Location information
• 1-on-1 voice/video calls
Note: We plan to expand Letter Sealing’s functionality in the future.

If you use LINE for PC with Letter Sealing enabled on the smartphone version of LINE, you will be required to verify your identity the first time you send a message.

For information about verifying your identity to use Letter Sealing on LINE for PC, see this Help article.
