What happens if a number is blocked in WhatsApp - briefly?
If you block someone's number on WhatsApp, they will no longer be able to contact you through the app. Additionally, their last seen status and online presence will not be visible to you.
What happens if a number is blocked in WhatsApp - in detail?
When a user blocks another person's phone number on WhatsApp, several changes occur to the communication dynamics between them. Here is a detailed breakdown of what happens:
-
Message Delivery: Any messages sent by the blocked individual will no longer be delivered to the recipient who has implemented the block. Instead, these messages will remain as "sent" in the blocked user's chat log, giving no indication that they were not received.
-
Read Receipts and Status Updates: The blocked user will not receive any read receipts (double blue ticks) from the recipient who has blocked them. Additionally, updates to the status, profile picture, or any other personal information shared by the blocked user will no longer be visible to the person who initiated the block.
-
Calls: Both voice and video calls made by the blocked individual to the recipient who has blocked them will fail to connect. The call logs on the blocked user's device will show "call ended" or "failed," but without any explicit indication that their number has been blocked.
-
Group Chats: If both users are part of a group chat, the blocked individual may still send messages within the group. However, the recipient who has blocked them will not receive these messages directly and will be unaware of their content unless another participant in the group shares it with them. The recipient can also choose to leave the group if they find the situation uncomfortable.
-
Visibility: The recipient who has implemented the block will still see the blocked user's name and number in their contact list, but any attempts to initiate a new conversation or call with that contact will result in no response from WhatsApp.
-
Data Retrieval: The blocked user cannot retrieve any previously sent messages or media files from the recipient who has blocked them. All communication history prior to the block remains on the blocked user's device, but they lose access to future interactions with the recipient.
-
Unblocking: If at some point the recipient decides to unblock the individual, all previous restrictions will be lifted. Messages sent by the previously blocked user during the block period will not be delivered retroactively; only new messages sent after the unblocking will be received normally.
In summary, blocking a number on WhatsApp effectively cuts off communication from that specific user without alerting them to the change in status. The recipient gains control over their interaction with the blocked individual while maintaining privacy and avoiding unwanted contact.
