Read Line Messages After Blocking: What Works

Card No. 06·30223 · Updated · Standard formula, shown below

If you’ve been blocked on Line, you can still see messages you sent before the block, but you cannot read new messages from that person, and your messages will not be delivered. This article explains exactly what happens to your chat history, what the other person sees, and whether any workaround can let you read their messages after being blocked.

How Blocking Works on Line

Line’s block feature is a privacy tool that stops all direct communication between two accounts. When someone blocks you, they disappear from your friend list, and you disappear from theirs. Any messages you send after the block are not delivered, and you won’t see their new messages, status updates, or profile changes. The block is one-way: the person who blocked you can still see your messages in their chat history, but you cannot see theirs.

What Happens to Your Existing Chat History

Your existing chat history remains on your device, but it becomes frozen. You can scroll back and read all messages that were exchanged before the block, including messages you sent and messages they sent. However, you cannot send new messages to them, and any message you try to send will show a failure or simply not deliver. The other person’s new messages (if any) will not appear in your chat, because the block severs the connection.

Can You Read Their Messages After Being Blocked?

No. Once blocked, you cannot read any new messages from that person. There is no official feature that lets you view their messages after a block. Some people try to use third-party apps or notification logs, but these are not reliable and often violate Line’s terms of service. The only way to read their messages again is if they unblock you, which is entirely up to them.

What the Person Who Blocked You Sees

When you send a message to someone who has blocked you, the message is not delivered. The sender (you) might see a “not delivered� error, or the message might appear as sent but never be read. The person who blocked you will not receive any notification about your message. They can still see your messages in their chat history if they scroll back, but they won’t see any new ones.

Common Misconceptions and Workarounds

Many people wonder if they can use a different account, a friend’s phone, or a screenshot to see the blocked person’s messages. Here’s the reality:

  • Using another account: If you create a new Line account and friend the person, you might see their public profile, but you won’t see their private chats with your original account.
  • Notification logs: On some Android devices, notification history might show a snippet of a message before it was blocked, but this is unreliable and not a full conversation.
  • Third-party apps: Apps that claim to “unblockâ€� or “read blocked messagesâ€� are scams or malware. They can compromise your account.

How to Check If Someone Blocked You

If you’re unsure whether you’ve been blocked, look for these signs:

  • Your messages are not delivered (no “readâ€� receipt).
  • The person’s profile picture and status updates are no longer visible.
  • You can no longer add them to a group or send a friend request.
  • Your chat history is still there, but new messages fail.

If you see these signs, you are likely blocked. However, the only definitive way is to ask the person through another channel.

Can You Unblock Yourself?

No. You cannot unblock yourself. Blocking is controlled entirely by the other person. You can delete the chat, but that doesn’t unblock you. The only way to resume communication is if the other person decides to unblock you, which they do by going to their settings, finding your profile, and selecting “Unblock.�

Privacy and Safety Considerations

Respecting the other person’s decision to block you is important. Trying to circumvent a block can be considered harassment and may lead to your account being reported or banned. Line’s terms of service prohibit using third-party tools to bypass privacy features. If you feel you have been unfairly blocked, consider reaching out through another communication method, but do not attempt to force contact.

Frequently Asked Questions

Can I still see their profile picture after being blocked?

No. When someone blocks you, their profile picture, status message, and last seen time become invisible to you. You will only see a default avatar or a blank space.

Will my messages be delivered if I send them after being blocked?

No. Messages sent after a block are not delivered. They may appear as sent on your end, but the recipient will never receive them, and you won’t get a “read� receipt.

Can I read their messages if I log into their account?

If you have access to their phone or account, you could technically read their messages, but that is a serious privacy violation and may be illegal. It is also against Line’s terms of service and could result in account suspension.

Does blocking delete the chat history?

No. Blocking does not delete any chat history. Both parties can still see past messages, but new messages are not exchanged.

Can I see if someone blocked me on Line?

There is no direct notification that says “you have been blocked.� You have to infer from the signs mentioned above, such as undelivered messages and the disappearance of their profile info.

If I delete the chat, will I lose the messages?

Yes, if you delete a chat, the messages are permanently removed from your device and cannot be recovered. This is separate from blocking, but it’s a common mistake to think that deleting a chat unblocks someone.
