If you delete a number in WhatsApp, will it be visible - briefly?
When you delete a contact's phone number from your WhatsApp, the change is not immediately visible to others. The deletion only affects your local device and does not propagate to other users' devices or the server.
If you delete a number in WhatsApp, will it be visible - in detail?
If you delete a number from your contacts list on WhatsApp, the visibility of that number depends on several factors. Firstly, deleting a contact from your device does not remove their phone number from WhatsApp's server. This means that if someone else has that contact saved in their phone and they send a message to that number, it will still be delivered to the intended recipient.
Secondly, if you have previously sent messages or made calls to that number using WhatsApp, those interactions will remain visible in your chat history. Deleting the contact from your device will only remove their name and profile picture from your contacts list; the conversation thread with that number will persist unless you manually delete it.
Moreover, if someone tries to send a message or make a call to the deleted contact using WhatsApp on your device, they might still be able to do so by entering the phone number directly into the search bar or the contacts list. This is because WhatsApp stores the phone numbers of all users who have registered with the service in its database for routing purposes.
Lastly, it is important to note that deleting a contact from your device does not prevent you from receiving messages or calls from that number on WhatsApp. The app will still deliver incoming communications based on the phone number associated with the account, regardless of whether the contact is saved in your device's contacts list.
In summary, while deleting a contact from your device removes their name and profile picture from your contacts list, it does not make their phone number invisible within WhatsApp. The visibility of that number depends on various factors, including previous interactions, manual search by others, and the app's database for routing purposes.
