You can stop unwanted calls and messages, and block or mark them as spam. When Google Voice suspects a call might be spam, it displays a warning on the incoming call screen and in your call history. You can then confirm whether or not the call is spam.
Important: If you feel you're in danger, contact your local emergency services.
When you block a number in Google Voice:
- Calls and messages from that number are marked Blocked .
- The blocked caller gets a "Number not in service" message when they call.
- You don’t get messages from that number.
