If a number is blocked in WhatsApp, can the subscriber see it - briefly?

If a number is blocked in WhatsApp, the subscriber will not be able to see any messages or calls from that specific number. However, there are no visible indicators on the blocker's end indicating that their number has been blocked by another user.

If a number is blocked in WhatsApp, can the subscriber see it - in detail?

When a number is blocked on WhatsApp, the user experience and visibility of interactions with that number are significantly altered. Here’s a detailed breakdown of what happens:

  1. Initial Message Delivery: If you try to send a message to a blocked number, it will fail to deliver. The system will indicate that your message was not sent, often displaying an error message such as "Failed" or "Delivery Failed." This is because the block prevents any communication from reaching the recipient.
  2. No Notification for Blocked User: The user who has blocked you will not receive any notification that they have been blocked. WhatsApp does not provide a direct way for users to know if someone has blocked them, maintaining a level of privacy and preventing potential confrontations or unwanted attention.
  3. Last Seen Status: If the blocked user tries to check your "Last Seen" status or profile picture, they will find that this information is no longer visible. WhatsApp restricts access to these details when a block is in place, further indicating that communication has been severed.
  4. No Delivery Receipts: When you send messages to the blocked number, you won’t see any delivery receipts (blue ticks) or read receipts (gray double-check marks). This absence of confirmation is a strong indicator that your messages are not reaching the intended recipient.
  5. Group Interactions: If both parties are part of the same group, interactions can still occur, but they will be limited. The blocked user will not see any updates to your profile picture or "Last Seen" status within the group, and you won’t receive any messages directly from them. However, you may still see their messages within the group chat, depending on the group settings.
  6. Calls: Similar to messages, calls to a blocked number will not go through. The call will fail, and you may see an error message indicating that the call could not be completed.

In summary, while WhatsApp does not explicitly notify users when they have been blocked, the absence of message delivery confirmations, "Last Seen" status visibility, and profile picture updates can serve as strong indicators. The platform prioritizes user privacy and prevents any direct notifications regarding blocks, ensuring that users cannot see if a number has blocked them directly.
