WhatsApp officially does not let the users know if they have been blocked by someone or not. But you can still do so using a few tips and tricks.
Using the tips and tricks available in WhatsApp FAQ section you can check who blocked you in just a snap
The first thing on the list is to check whether you’re able to see the last seen of the contact. WhatsApp suggests that if you aren’t able to see the last seen, then there are slight chances that you have been blocked by that person.
If that’s the case, then you should next check the status of that contact. You won’t be able to see the status if that person has either blocked you or has hidden their status.
In the next step, you need to check the profile photo of the contact.
You won’t be able to see the profile photo if that person has blocked you.
However, another possibility is that the person has deleted your contact and set their profile picture of ‘My contacts’ or ‘no one’.
In the final steps, you can try calling that contact via WhatsApp. If the call doesn’t go through then there are major chances then you have been blocked by that person.
You can finally try texting the person. If your message doesn’t get two ticks, then the chances of you being blocked will increase.
You can try adding that contact to a WhatsApp group. You won’t be able to add contacts to a WhatsApp group if you have been blocked by the contact.
