But before we go into the matter, it should be made clear that there is no foolproof method that will let us know, although there is some evidence that might be indicative of a person blocking us.

To find out if a user has blocked us on WhatsApp, we have to look at different signals:

  • We can no longer see their last time online, nor do we see them online on the chat screen.
  • We cannot see their profile picture.
  • All messages sent to you are left with a single tick (indicating that the message has been sent), but the second tick (indicating that it has been received) never appears.
  • No calls of any kind can be made to that person.

From the official website of WhatsApp, they clarify that, however, none of these assumptions is definitive and irrefutable evidence. Other causes that have nothing to do with the blockage could be the reason why we went through one (or several) of the phases described above.

There is a very common trick that is quite reliable (although there is also room for error), which is to try to add a group to a contact that we are not sure has us blocked. To find out, open WhatsApp and tap on the menu button:

Look for a contact that you think has us blocked, select it and tap on the arrow button

Selecting the suspicious contactSelecting the suspicious contact

You will get to this screen, where you will have to name the group and create it by tapping, again, on the green button:

If when creating the group a message appears on the screen announcing that we cannot add that contact to the group, or we only appear as members of the group, it means that, most probably, that contact has blocked us.
