You can tell if someone has blocked you on WhatsApp by looking for several signs, since WhatsApp does not notify you directly when you are blocked. Key indicators include:

• No "Last Seen" or Online Status: You cannot see the person's last seen timestamp or when they are online in the chat window. However, this might also happen if they changed their privacy settings to hide this information from everyone

• Profile Picture Disappears or Stops Updating: You no longer see their profile photo, or it remains unchanged for a long time, which can indicate blocking but might also mean they just stopped updating it

• Messages Show Only One Checkmark: When you send a message, you see only one gray checkmark (message sent) but never get the second checkmark (message delivered). This usually means your messages are not reaching them, possibly because you are blocked. However, network issues can also cause this

• Unable to Make WhatsApp Calls: Calls you place through WhatsApp to that contact do not go through or do not ring, which strongly suggests blocking

• Cannot Add Them to a Group: If you try to add the person to a WhatsApp group, you either get an error or the person does not appear in the group members list after adding them, indicating they have blocked you

No single sign confirms blocking definitively, but if you observe multiple of these indicators together, it is very likely you have been blocked on WhatsApp

. Summary of main signs:

Indicator| What it Means
---|---
No last seen/online status| Possibly blocked or privacy hidden
No profile photo or no updates| Possibly blocked or no photo updates
One checkmark on messages only| Messages not delivered (possible block)
Calls don’t go through| Likely blocked
Cannot add to groups| Likely blocked

Checking these signs together gives the best clue if someone blocked you on WhatsApp
