How do I block all unknown numbers in WhatsApp - in detail?

Blocking unknown numbers on WhatsApp can significantly enhance your privacy and reduce unwanted messages. While WhatsApp does not provide a built-in feature to block all unknown numbers at once, you can achieve this through a combination of settings and manual adjustments. Here's a detailed guide on how to do it:

1. Update Your Privacy Settings:

   • Open WhatsApp and go to the "Settings" tab (usually represented by three dots).
   • Navigate to "Account" > "Privacy".
   • Under "Last Seen", "Profile Photo", and "About", select "Nobody". This ensures that your information is not visible to anyone who is not in your contact list.

2. Block Unknown Contacts Manually:

   • When you receive a message from an unknown number, open the chat.
   • Tap on the three dots at the top right corner of the screen.
   • Select "More" > "Block". Confirm by tapping "Block" again. This will block the specific contact.

3. Use Third-Party Apps:

   • For a more comprehensive solution, consider using third-party apps designed to filter and block unknown numbers. Examples include "TrueCaller" or "Mr. Number". These apps can identify unknown callers and allow you to block them easily.

4. Regularly Check and Block New Contacts:

   • Make it a habit to regularly check your WhatsApp contacts list for any unknown numbers.
   • If you find an unknown contact, follow the steps above to block them manually.

5. Use WhatsApp Business API (For Businesses):

   • If you are using WhatsApp Business API, you can implement more advanced blocking features through custom-built solutions or third-party integrations. This requires some technical knowledge and may involve additional costs.

By following these steps, you can effectively block unknown numbers on WhatsApp and maintain a higher level of privacy and security.
