How to automatically block unknown numbers on Whatsapp?

To automatically block unknown numbers on WhatsApp, you can follow these steps:

Open the WhatsApp application: Make sure you have installed the WhatsApp application on your phone and log in to your account.

Navigate to Settings: On the main WhatsApp interface, tap the menu button in the upper right corner, usually three vertical dots or lines.

Go to Privacy Settings: In the menu, find and tap the "Settings" option, then select "Account" or "Privacy."

Configure Privacy Settings: On the Privacy Settings page, you will find options to control who can contact you and who can see your information. Here are a few potentially relevant options:

"Who can send me messages": Make sure this option is set to "My Contacts", this will limit only the contacts you have saved in your address book from sending you messages.

"Who can see my profile picture": Select "My Contacts" to ensure that only people in your contacts can see your profile picture.

"Who can see my status": Select "My Contacts" to limit that only those in your contacts can see your status updates.

Block unknown numbers: Although WhatsApp does not provide an option to block unknown numbers directly, you can manually block unknown numbers by following the steps below:

When receiving a message from an unknown number, do not reply or interact with it.

Add unknown numbers to your phone's blacklist or blocklist. You can find these options in your phone's settings, and the steps may vary by phone model.

Note that the ability to automatically block unknown numbers may depend on your phone's operating system and WhatsApp application version. If you can't find a specific auto-block option, check that your WhatsApp app is up to date and check the relevant settings for your phone's operating system.
