If I change my number in WhatsApp, will people see the new number - briefly?
If you change your number on WhatsApp, contacts within your phone's address book who also use WhatsApp will automatically see and be able to message you using your new number. However, for people not in your phone's contact list, they will only see the new number if you manually inform them or update it in their contact list.
If I change my number in WhatsApp, will people see the new number - in detail?
When you change your phone number on WhatsApp, there are several considerations to understand regarding the visibility of this update to your contacts.
Firstly, it's important to clarify that changing your phone number in WhatsApp does not automatically notify all your contacts about the new number. The process involves updating your account settings with the new number, and WhatsApp will attempt to migrate your chat history, groups, and settings to the new number. However, this change is not broadcasted or announced to your entire contact list.
Secondly, if someone tries to message you on the old number, they will receive a notification indicating that your phone number has changed. This prompt will advise them to update their address book with your new phone number. It's crucial for users to understand this mechanism, as it ensures that contacts have the correct information without WhatsApp explicitly sharing the new number.
Lastly, if you want your contacts to be aware of your new number proactively, you might need to manually inform them. This can be done through a group message or individually via another communication platform. While WhatsApp handles the technical migration, it does not automatically disseminate the new phone number to all your contacts.
In summary, changing your phone number on WhatsApp will not broadcast the new number to all of your contacts. Instead, they will be notified if they attempt to contact you using the old number. For a broader update, manual communication is recommended.
