You’ve Blocked/Unblocked Someone: What’s Next?

You might be wondering what happens when you block someone on WhatsApp, do they know? Thankfully, they won’t be notified that you’ve blocked or unblocked them. However, you won’t be able to receive their messages when you’ve blocked them, which they might notice.

If you decide to unblock a contact after you’ve blocked them, there is no notification to them that they are unblocked. However, the unblocking will mean they can then see your profile photo, last seen and any status updates you make. You won’t receive any messages the contact tried to send you while they were blocked, but you will start to receive any new ones they send as soon as you’ve unblocked them.

How to Know if Someone Has Been Blocked

Because of the way WhatsApp works, you will be able to see if you’ve been blocked by using some key indicators. You won’t, however, receive a notification.

Firstly, you won’t be able to see their ‘last seen’. So, if you go to the contact in question, the space where you can see their online status or ‘last seen’ won’t be visible. However, this isn’t definite because it is possible to alter your privacy settings not to show ‘online’ and ‘last seen,’ which could be what they’ve done. For example, you could choose to show your ‘last seen’ to nobody, your contacts, or everyone.

Another indicator is if you can’t see their profile picture and information. You won’t see statuses or stories either if you’re blocked. However, this could also mean that the person has deleted WhatsApp altogether and not just blocked you.

You can also tell whether or not you could be blocked by the checkmarks in your sent messages. If only a single gray checkmark is visible, it means your message has been sent but not delivered. This could be due to their phone being off or them having no signal, but if it’s been a while, then it’s probably because you’re blocked.


Hopefully, you can now block contacts in WhatsApp easily. Whichever method you choose, be aware that although the contact won’t get notified that you’ve blocked them, they could use some of the indicators we’ve discussed above to work out whether they’re blocked or not! Don’t worry, though. If you’ve decided to block someone, you’ve probably got a reason that trumps them finding out they’re blocked, which is more important.
