Viber Block Someone Without Them Knowing?
Yes, you can block someone on Viber without them receiving a notification, but they will likely figure it out from the changes in your chat behavior. When you block a contact, Viber does not send an alert to the blocked person; instead, they will simply see that their messages are no longer delivered and your online status disappears. This article explains exactly what happens when you block someone, how to do it discreetly, and what signs might give it away.
How Blocking Works on Viber
Blocking a contact on Viber is a one-way action that stops all communication from that person to you. Once you block someone:
- They cannot send you messages, and any messages they try to send will show a single check mark (sent but not delivered) on their end.
- They cannot see your online status, last seen timestamp, or when you are typing.
- They cannot call you, and their calls will not ring on your device.
- They cannot see your profile photo updates or your “About” information.
- If you are in a shared group chat, the blocked person will still see your messages in that group, but they cannot message you directly.
Importantly, Viber does not send a push notification or an in-app alert saying “You have been blocked.” The blocked person is left to infer it from the lack of delivery receipts and the disappearance of your online presence.
How to Block Someone on Viber (Step-by-Step)
Blocking a contact takes only a few taps, and the steps are identical on Android and iOS. Here is how to do it:
- Open Viber and go to the Chats tab.
- Find the conversation with the person you want to block, or open their profile from your Contacts list.
- Tap the person’s name at the top of the chat to open their info page.
- Scroll down and tap Block (or the three-dot menu and select Block).
- Confirm the action when prompted. You can also choose to Report spam at the same time, but that is optional.
After blocking, you will see a banner in the chat saying “You have blocked this contact.” The person on the other end gets no such message.
What the Blocked Person Sees (Signs That Reveal It)
Even though there is no direct notification, the blocked person will almost certainly notice within a few messages. Here are the telltale signs from their perspective:
- Their messages to you show only one check mark (sent) and never turn to two checks (delivered).
- Your online status and last seen timestamp disappear from their chat screen.
- They cannot see your profile photo or your About text anymore.
- If they try to call you, the call goes through but never connects to your phone; it just rings until they give up.
- They cannot add you to a new group chat (if they try, they get an error).
If the person is technically savvy, they may also notice that your messages in a shared group still appear, but their direct messages never get delivered. This combination of clues makes blocking fairly easy to detect, even without an explicit alert.
Can You Block Someone and Still See Their Messages?
No. When you block someone on Viber, you also stop seeing their messages. The chat disappears from your main chat list and moves to a Blocked contacts section in your settings. You will not receive any new messages from them, and you cannot see their profile updates. If you unblock them later, the chat history reappears, and any messages they sent while blocked will not be delivered retroactively—they will have to send them again.
Common Misconceptions About Viber Blocking
There are a few myths that circulate about blocking on Viber. Here is what is actually true:
- Myth: The blocked person gets a “blocked” notification. False. Viber never sends such an alert.
- Myth: Blocking removes you from shared groups. False. You remain in any shared group chats, and the blocked person can still see your messages there.
- Myth: Blocking deletes the chat history. False. The chat is hidden while blocked, but it is restored if you unblock the person.
- Myth: The blocked person can see your “last seen” if they are in a group with you. False. Blocking hides your online status and last seen from that person everywhere, including in group chats.
How to Unblock Someone (and What Happens Then)
If you change your mind, unblocking is just as simple:
- Open Viber and go to Settings (the gear icon).
- Tap Privacy (or Account on some versions).
- Select Blocked contacts.
- Find the person in the list and tap Unblock next to their name.
Once unblocked, the person can send you messages again, and your chat history reappears. They will not receive a notification that you unblocked them either, but they will see that their new messages now get delivered.
Alternatives to Blocking: Muting and Hiding
If you want to avoid someone without the full block, Viber offers two softer options:
- Mute notifications: This stops message alerts from that person but still lets them send messages and see your online status. They will never know you muted them.
- Hide chat: This removes the chat from your main list without blocking the person. They can still message you, and you will see the chat if they send something new, but it stays hidden otherwise.
These options are useful if you want to avoid constant notifications but do not want to sever the connection entirely.
Frequently Asked Questions
Will the person know I blocked them on Viber?
No, Viber does not send a notification when you block someone. However, they will likely deduce it from the signs: messages not being delivered, your online status disappearing, and calls not connecting.
Can I block someone without them seeing my “last seen”?
Yes. Blocking automatically hides your online status and last seen timestamp from the blocked person. If you only want to hide your status without blocking, you can change your privacy settings to “Nobody” for last seen.
What happens to group chats when I block someone?
You both remain in the group, and the blocked person can still see your messages in that shared group. However, they cannot message you directly, and you will not see their messages in the group either.
If I block someone, can they see my profile photo?
No. Blocking hides your profile photo, About text, and any other profile updates from the blocked person. They will see a default avatar instead.
Does blocking delete the chat history?
No. The chat is simply hidden from your main list while the person is blocked. If you unblock them later, the chat history reappears intact.
Can I block someone who is not in my contacts?
Yes. You can block any person who has messaged you, even if they are not saved in your contacts. Open the chat, tap their name, and choose Block.
