How to Block Private Number Calls on Your US Phone

Receiving calls from private or unknown numbers can be a nuisance. Fortunately, there are several ways to block these calls on your US phone.

What Are Private Number Calls?

Enable Silence Unknown Callers: Toggle on "Silence Unknown Callers."

This feature silences calls from numbers not in your contacts, recent calls, or Siri Suggestions. These calls will go straight to voicemail, and you can check them later. Be aware that this may also silence calls from legitimate unknown numbers. (techradar.com)
