What happens if you block a number on WhatsApp - briefly?
When you block a number on WhatsApp, the blocked user will no longer be able to send messages or calls to your number. Additionally, their last seen status and online presence will not be visible to them.
What happens if you block a number on WhatsApp - in detail?
When you block a number on WhatsApp, several changes occur in the communication dynamics between your account and the blocked contact. Firstly, any messages sent by the blocked contact will not be delivered to your phone. Instead, they will remain undelivered on the sender's end, indicated by a single checkmark but no double checkmarks or read receipts. This means you won't see any notifications for these messages, and they won't appear in your chat list either.
From your perspective, blocking a number also prevents you from seeing their online status or any changes to their profile picture. Any calls made by the blocked contact will not ring on your device; instead, they will go directly to voicemail if that feature is enabled on your account. It's important to note that while the blocked contact cannot see your last seen status or online presence, you can still view their information if you have it saved in your contacts.
Additionally, any groups you share with a blocked contact will remain unaffected. Both you and the blocked contact can continue to participate in group conversations, but neither of you will receive notifications for individual messages sent directly by the other party within the group. However, if you remove the blocked contact from the group, they will no longer be able to see or participate in group chats.
Lastly, it's worth mentioning that blocking a number on WhatsApp is a two-way street. If the blocked contact tries to add your number back into their contacts, they won't receive any notifications from you unless you unblock them first. Moreover, if you decide to unblock the contact in the future, you will need to manually add their number back to your contacts list for communication to resume normally.
In summary, blocking a number on WhatsApp effectively silences all direct communications from that contact while allowing group interactions to continue seamlessly. This feature serves as a useful tool for maintaining control over your messaging environment and ensuring privacy when needed.
