How to Block Private Numbers on iPhone 12: A Step-by-Step Guide

Are you tired of getting calls from private numbers on your iPhone 12? Blocking them is a simple solution that can give you peace of mind. By following a few easy steps, you can prevent these calls from interrupting your day.

Step by Step Tutorial: How to Block Private Numbers on iPhone 12

Before we dive into the steps, let’s understand what we’re trying to achieve. By blocking private numbers, we’re essentially telling our iPhone 12 to reject calls from anyone who has hidden their caller ID. This means you won’t even see these calls come in; they’ll be silently blocked.

Step 1: Open the Settings app

Access your iPhone 12’s settings by tapping on the gear icon on your home screen.

The Settings app is where you can customize various aspects of your iPhone 12, including privacy settings and call blocking.

Step 2: Scroll down and tap on ‘Phone’

In the Settings menu, find the option labeled ‘Phone’ and tap on it to access your call settings.

This section of your settings allows you to manage call-related features, such as call forwarding, voicemail, and, importantly, call blocking.

Step 3: Select ‘Silence Unknown Callers’

Within the Phone settings, look for the option ‘Silence Unknown Callers’ and tap on it.

When you enable this feature, calls from unknown numbers—those not in your contacts, not recent outgoing calls, and not Siri Suggestions—will be silenced, sent to voicemail, and listed in your recent calls.

Step 4: Toggle the switch to the right

You’ll see a switch next to ‘Silence Unknown Callers.’ Toggle it to the right to turn the feature on. It will turn green when activated.

Activating this setting doesn’t block private numbers per se, but rather silences them, which is the closest available option on iPhone 12. Blocked calls will go straight to voicemail without ringing your phone.

Once you’ve completed these steps, calls from private numbers will no longer disrupt your day. Instead, they’ll be diverted straight to voicemail, and you can choose whether or not to listen to them at your leisure.

Tips: Enhancing Your Experience While Blocking Private Numbers on iPhone 12

  • Keep your contacts updated. Make sure to save numbers you know and trust to ensure their calls aren’t silenced.
  • Check your voicemail regularly. Just because you’ve silenced unknown callers doesn’t mean you should ignore potential important messages.
  • Consider using Do Not Disturb mode for additional peace. This mode can silence all calls, except from your favorites or repeated calls.
  • Remember that emergency services can still reach you. Even with unknown callers silenced, calls from emergency numbers will always come through.
  • Don’t forget to disable the feature if you’re expecting an important call from an unknown number.
