How to know if I'm blocked on WhatsApp?

There are a couple of indicators that you may be blocked:

1. You can no longer see a contact's last seen or online in the chat window.


2. You do not see updates to a contact's profile picture.


3. Any messages sent to a contact who has blocked you will always show one check mark (message sent), and never show a second check mark (message delivered).


4. Any calls you attempt to place will not go through.
