How can you know if someone has your phone number on WhatsApp?

WhatsApp does not have a built-in feature that allows you to see if someone has your phone number. However, there are a few ways you can find out if someone has your phone number on WhatsApp:

1. Check your WhatsApp contacts: WhatsApp automatically syncs with your phone's contacts, so if someone has your phone number saved in their contacts, they will be able to see your profile picture, status, and other information on WhatsApp. You can check your WhatsApp contacts by opening the app and tapping on the "Chats" tab. If you see the person's name or profile picture, it means they have your phone number.
2. Ask them directly: If you suspect that someone has your phone number on WhatsApp but you're not sure, you can always ask them directly. You can send them a message on WhatsApp or call them to confirm.
3. Look for their profile picture or status: If someone has your phone number on WhatsApp, you will be able to see their profile picture and status. If you can't see their profile picture or status, it could mean that they have blocked you or deleted their account.
4. Check for mutual groups: If you and the person are members of the same WhatsApp group, it means that they have your phone number. You can check your WhatsApp groups by opening the app and tapping on the "Groups" tab.

It's important to note that even if someone has your phone number on WhatsApp, it does not necessarily mean that they will message you or add you to their contacts. WhatsApp respects users' privacy, and users have the option to control who can see their profile picture, status, and other information.
