To block all unknown numbers in WhatsApp, you can use the app's settings to filter messages from unknown senders. This feature ensures that only contacts saved in your phone can message you directly.

How to block all unknown numbers in WhatsApp - in detail?

To effectively block all unknown numbers in WhatsApp, you can follow these detailed steps:

1. Update Your WhatsApp: Ensure your WhatsApp application is updated to the latest version. This will provide you with the most recent features and improvements related to privacy settings.

2. Adjust Privacy Settings:

   • Open WhatsApp and tap on the three dots (⋮) in the upper-right corner to access the menu.
   • Select "Settings."
   • Tap on "Account" and then "Privacy." Here, you'll find several options that can help you manage who can see your profile picture, status, and more.

3. Block Unknown Contacts:

   • Within the Privacy settings, tap on "Contacts." This setting allows you to control who can add you to groups or call you.
   • Set it to "Nobody" if you want to block all unknown contacts from reaching out to you. Be aware that this will also prevent known contacts from adding you to groups unless you've saved their number in your phone’s contact list.

4. Use the Block Feature:

   • If you receive a message or call from an unknown number, you can block that specific number directly:
     • Open the chat with the unknown number.
     • Tap on the three dots (⋮) in the upper-right corner of the screen.
     • Select "Block" to add the contact to your blocked list.

5. Enable Two-Step Verification:

   • Although this feature doesn’t block unknown numbers directly, it adds an extra layer of security to your WhatsApp account:
     • Go back to Settings and tap on "Account."
     • Select "Two-step verification" and follow the prompts to set up a PIN. This will ensure that even if someone tries to access your account using an unknown number, they won’t be able to do so without the PIN.

6. Review and Manage Blocked Contacts:

   • To review or unblock contacts you've blocked, go back to Settings.
   • Tap on "Account," then "Privacy," and finally "Blocked contacts." Here, you can see a list of all the numbers you’ve blocked and manage them as needed.

By following these steps, you can significantly reduce the likelihood of receiving unwanted messages or calls from unknown numbers in WhatsApp.
