Checking which chat messages were sent and which are read/unread

When a friend sees a message you sent them on LINE, "Read" will appear to the left of that message.

In group chats, numbers displayed next to "Read" (e.g. Read 2) indicate the number of people who have seen your message.

Depending on the recipient's device, a message may be marked as "Read" when they receive a notification for it. As such, the Read receipt doesn't necessarily mean that your chat message has been seen.

Also, the time that appears next to "Read" is the time you sent the message, not the time someone checked it.

Please use Read receipts as an approximate guide to whether or not your messages have been seen.

This is a marker that indicates the point up to which messages have been read and where unread messages begin.

"Unread messages below" appears in chats with one or more unread messages.

Messages that were sent successfully will have no icon next to them.

This icon may appear if your smartphone's network connection is unstable. Try sending your message in an area with a strong network connection.

If your message couldn't be sent due to a network error, a button to resend it will appear. After letting some time pass, try sending the message again by tapping > Resend.

This icon appears next to messages that were sent while an error was occurring with the server for sending/receiving messages. After letting some time pass, try sending the message again by tapping the chat with > > Resend.
