How can you change your WhatsApp number without losing data?

If you want to change your WhatsApp number without losing data, you can follow these steps:

1. Back up your chats: Before changing your WhatsApp number, make sure to back up your chats to Google Drive or locally on your device. To back up your chats, go to WhatsApp Settings > Chats > Chat Backup and tap "Back Up Now."
2. Save your media files: Make sure to save any important media files, such as photos and videos, to your device or cloud storage before changing your WhatsApp number.
3. Verify your new number: Install WhatsApp on your device and verify your new number. Make sure to use the same phone number that you want to switch to.
4. Restore your chats: During the setup process, WhatsApp will ask if you want to restore your chats from a backup. Select the backup that you created before changing your number and follow the prompts to restore your chats.
5. Notify your contacts: Once you have changed your WhatsApp number and restored your chats, make sure to notify your contacts of your new number. You can use the "Change Number" feature in WhatsApp to notify your contacts automatically.

Note that changing your WhatsApp number will not affect your group chats. You will remain in your group chats, but your old phone number will be removed and replaced with your new phone number.

Additionally, if you have enabled two-step verification on WhatsApp, make sure to disable it before changing your number. Once you have changed your number, you can enable two-step verification again using your new phone number.
