LINE Official Account manual and Help (Only available in Japanese.)
The name of an official account has a gray, blue, or green icon next to it, and the type can be distinguished by the icon color.
Adding an official account as a friend lets you ask questions via chat and get access to other convenient services.

To select an account from Find official accounts:
1. Tap the Home tab > Friends > the Official accounts tab > Find official accounts.

There has been an increase in cases of unauthorized logins that we believe are due to the use of easy-to-guess passwords.
If someone has logged in to your LINE account through a web service, it means they are able to log in to any other services linked to your LINE account (including both those offered by LINE and other companies).
Note: "Logging in through a web service" means using your email address and password registered to LINE to log in to another service linked to your account via a web browser (and not the LINE app).
If someone knows your information, it is also possible that they could use your email address and password to make unauthorized logins to other services that are not related or linked to LINE.
If you found that someone has made an unauthorized login to your account through a web service, make sure to do the following.
• Turn on Two-factor authentication.
Follow the steps to strengthen security for web logins.
• Block the official accounts of the service that was used.
In some cases, when you log in to a web service with LINE it adds that service's official account as a friend. Go to the Home tab > Friends > Official accounts and block the account of the relevant service if it was added.
• Deauthorize the LINE app from the web service that was used.
The web service that was used may be linked to your LINE account. Deauthorize the service by selecting the Home tab > Settings > Account > Authorized apps > the relevant service > Deauthorize > OK.
• Log out from the website of the service that was used.
Changing the password of your LINE account will not automatically log you out of any web services. Also, deauthorizing the LINE app from a service may not log you out in some cases. Make sure to log out of the relevant web service in addition to taking the measures listed above.
Note: With some companies' services, you can see a list of which devices are logged in. If there are any devices that are logged in to the service, make sure to log out from those devices in addition to logging out from the service's website. For more details on how to do so, please contact the relevant service provider directly.

The steps to start a voice/video call with a LINE official account are as follows.
Be advised
- We have received reports of blackmail occurring due to abuse of the voice and video call features. Please take care not to make video calls of a private nature that could put you at any kind of risk, and refrain from calling or accepting calls from anyone who you do not know or trust.
- If you find the content to be inappropriate during a call with a LINE official account, please report and block the relevant official account.
Useful info
- For a LINE official account to receive calls from users, the account's administrator needs to set it up.
- If you don't see
, you won't be able to use the call feature because it wasn't set up.
Starting voice calls with LINE official accounts:
To make a call from an official account's profile page:

Note: If the official account can use voice calls, you'll see "Free" under.
2. Tap Start call.
To make a call from a chat:
1. Tap Call in the call request message you receive from the official account.
2. Tap Start call.
Call requests may only be valid for a limited time. For details, see the "Limited-time call requests" section in this Help article.
If you're using a 4G or 5G network, you may be charged for the data used during a call. We recommend using a flat-rate data plan. Also, if call quality is low, try using a Wi-Fi connection.
Starting video calls with LINE official accounts:
1. Start a call from the official account's profile page or chat.
2. On the voice call screen, tap the video camera icon.
Note: If the official account's administrator has not allowed video calls in their settings, you will not be able to switch to a video call.
Limited-time call requests:
If a call request from a LINE official account says it will expire after 30 minutes, it means you need to make your call to the account within 30 minutes of receiving the request.
Once your voice or video call has started, you can keep talking with the official account for as long as you like.
After 30 minutes have passed, you will no longer be able to use a call request. In this case, please ask the official account to send you a call request again.

This Help article will explain the messages sent from the LINE official accounts of companies you aren't friends with.
Useful info
If you received a message not from a company's official account but from someone you don't know, try the steps in Preventing chat messages from people you don't know and group invitations.
About the icons used for LINE official accounts:
The name of a company's official account has a gray, blue, or green icon next to it, and the type can be distinguished by the icon color. 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.
About messages from the official accounts of companies you didn't add as friends:
You may get notification messages from the official accounts of companies. These are messages for things like package delivery dates and when bills are due.
These notification messages let you receive helpful information without having to add the official accounts of individual companies as friends on LINE.
How notification messages work:
Companies request to send messages on LINE based on their customers' phone numbers that they have on file. A notification message will be sent if we've confirmed at the time of sending that:
• The phone number the company has on file matches your phone number registered to LINE.
• Your LINE account allows notification messages.
• Your LINE account has not blocked the company's official account.
For security reasons, we use a special method to change (encrypt) the phone numbers sent to us by companies. We only use the relevant information to send messages to the correct user, and delete the information immediately after finishing confirmation.
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.
Note: You may need to verify your identity with your phone number via an official account that we operate to have these notification messages sent to you.
About messages to verify your phone number:
The message to verify your phone number is for verifying your phone number regularly (every 180 days) to confirm that the phone number registered to your LINE account is the same as your currently contracted phone number.
Note: Once verified, the message won't be sent again for 180 days.
The phone number shown in the phone number verification message is shown in the following format: (international calling prefix)(country code)(phone number, minus any 0 at the beginning).
Note: To protect your privacy, only part of your phone number is shown (e.g. a Japanese phone number of “070-0000-0000” would be shown as “+817****00000”).
If your phone number registered to LINE is different from your currently contracted phone number:
• You'll become unable to receive helpful notification messages (e.g. package delivery dates, bills that are due) from the official accounts of companies.
• You may suddenly become unable to use LINE.
For the steps to check or change the phone number registered to your account, see the following Help article.
Changing your phone number
Turning off notification messages:
If you don't want to receive notification messages, do either of the following.
• Turn OFF notification messages.
• Block the relevant LINE official account.
Note: The “LINE” official account is our system account and cannot be blocked.
