How to silence unknown callers

Anyone who has your phone number can call you on WhatsApp. But you can block a known phone number or choose to silence calls from unknown callers by changing your privacy settings.
Silencing calls from unknown callers means you can focus on conversations that matter to you, while preserving your privacy and preventing unwanted contact.
An unknown caller could be someone you haven’t contacted or saved as a contact before.
Silence unknown callers
  • On Android and iOS:
  • Tap Settings > Privacy.
  • Tap Calls.
  • Move the toggle to the on or off position.
You’ll still see silenced calls from unknown callers in the Calls tab and in Notifications, but your phone won’t ring.
You can call an unknown caller back from within the Calls tab. Alternatively, tap the Silenced unknown caller message within a chat.
Note: If you call or message the silenced caller, you won’t be able to silence their calls in future.
You can stop receiving calls from other WhatsApp users by blocking them.
