1. The foremost indicator is that you will not be able to see the contact’s last seen or online status
in the chat window. That being said, it could however also be because of the privacy settings selected by the user. But it is definitely an easy way to check if you have been blocked.2. The second indicator is the profile picture of the contact would not be visible, if so, then there is a high probability that the person may have blocked you on the platform.
3. The third big indicator of being blocked on WhatsApp is when sending a message to that contact, only a check mark (message sent) would show on the message. Once blocked, it will never show another check mark, which appears only when the message is delivered.
4. Furthermore, this can also be confirmed by trying to make any kind of call (voice and video) to the contact. If blocked, the call won’t connect.
If a user sees all the above indicators for a contact, it could mean that the user has blocked him or her. However, there are other possibilities as well. On its FAQ page, WhatsApp says it has intentionally made it ambiguous to protect user privacy when blocking someone.
