If you change your phone number in WhatsApp, will your contacts know about it - briefly?
No, your contacts will not automatically be notified if you change your phone number on WhatsApp. However, the app provides a convenient feature to inform them manually through a broadcast message.
If you change your phone number in WhatsApp, will your contacts know about it - in detail?
If you change your phone number in WhatsApp, the impact on your contacts' awareness of this change depends on several factors.
Firstly, when you update your phone number within the app, WhatsApp does not automatically notify all your contacts about the change. This means that if a contact tries to message you using your old number, they will receive an error message indicating that the number is no longer registered with WhatsApp. This can alert them to the fact that your number has changed, but it is not a guaranteed method of communication.
Secondly, if you have enabled the "Change Number" feature within the app's settings, WhatsApp will attempt to migrate your account information and chat history to the new phone number. This process allows you to retain your profile picture, about section, groups, and settings associated with your old number. During this migration, some of your contacts may receive a notification stating that your number has changed. However, the visibility of this notification is limited; it does not guarantee that all your contacts will be informed about the change.
Lastly, if you want to ensure that all your contacts are aware of your new phone number, it is advisable to manually inform them through other means of communication such as email, social media, or by sending a broadcast message using WhatsApp itself before making the switch. This proactive approach ensures that everyone in your contact list knows about the change and can update their records accordingly.
In summary, while WhatsApp provides some level of notification about phone number changes, it is not comprehensive or guaranteed. For complete assurance, users should take additional steps to inform their contacts manually.
