Can You Find Out If Someone Blocks You on WhatsApp?

Yes, you can. There are many ways to find out.
Here are some things to consider if you think someone blocked you:
1. The ‘Last Seen’ function will not appear on the screen.
2. The profile picture will not appear.
3. If you send a message to someone, it will only receive one checkmark. This means that you sent the message but it hasn’t been delivered to the WhatsApp user yet.
4. You will not be able to call your contact.
