What is an Unknown Caller

On your iPhone, an unknown caller is someone who is not in your Contacts list, which is an address book stored on your device that can be accessed through the Phone or Contacts apps. If you have called a number recently, your iPhone will not consider that number an unknown caller if they call you back.

Apple includes a feature with iOS 13 and up that allows you to silence rings and notifications from unknown callers, which is covered below. This does not include numbers you have called recently. Otherwise, if you want a caller not to be considered unknown (and thus not be silenced) you will need to add the number to your iPhone’s Contacts.

How to Silence Unknown Callers

First, to silence these calls, open Settings on your iPhone by tapping the grey gear icon on your Home screen. Refer to the below image:

Next, in Settings, scroll down and tap Phone. See the below image:

Next, in Silence Unknown Callers settings, enable the switch beside Silence Unknown Callers to ON. Refer to the below image:

Now, exit Settings. The next time you get a call from an unknown number, you will not hear a ring or a notification sound. The call will be sent to voicemail, and it will appear in your recent calls list in the Phone app. You may still get a notification if the caller leaves a voicemail.

If you are expecting an important call from an unknown number in the future, open

Settings > Phone > Silence Unknown Callers

and then switch Silence Unknown Callers to OFF. Incoming calls will no longer be silenced.
