How to Block Unknown Callers on iPhone: A Step-by-Step Guide

April 18, 2025 By Matthew Burleigh

If you’re tired of unknown callers disturbing your peace on your iPhone, there’s a simple solution. You can block these callers in just a few taps. By adjusting your phone settings, you’ll ensure only known contacts ring through, keeping those unknown numbers at bay. This guide will walk you through the steps to silence those mystery callers efficiently.

How to Block Unknown Callers on iPhone

Blocking unknown callers on your iPhone will help reduce those pesky interruptions from unfamiliar numbers. By following these steps, you’ll be in control of who gets to reach you.

Step 1: Open Settings

To begin, open the "Settings" app on your iPhone.

The Settings app is where you can control just about everything on your iPhone, from sound settings to privacy preferences. Finding it is easy—just look for the gear icon on your home screen.

Step 2: Scroll to Phone

Scroll down and tap on "Phone" to access call settings.

The Phone settings section is where you can manage all things related to calls. Here, you’ll find options for call forwarding, call waiting, and, of course, call blocking.

Step 3: Tap Silence Unknown Callers

Find and tap "Silence Unknown Callers."

This option does exactly what it says. It sends calls from numbers not in your contacts, Siri Suggestions, or recent outgoing calls straight to voicemail.

Step 4: Toggle the Switch

Turn on the "Silence Unknown Callers" switch.

Once you toggle this feature on, your iPhone will silence calls from unknown numbers, sending them directly to voicemail. You can always check voicemails later to see if any important calls slipped through.

Step 5: Verify Changes

Make sure the change is activated by seeing the green switch.

A quick glance at the switch will confirm if it’s active. When it’s green, unknown callers will be automatically silenced.

When you complete these steps, your iPhone will no longer ring for calls from unknown numbers. Instead, those callers will be directed to voicemail, ensuring your phone only rings when it’s someone you know.

Tips for Blocking Unknown Callers on iPhone

  • Keep Contacts Updated: Regularly update your contact list to ensure important numbers aren’t silenced.
  • Check Voicemail Regularly: Unknown callers will go to voicemail, so check it to ensure you don’t miss anything crucial.
  • Review Your Call Log: Occasionally look through your call log to identify any unknown numbers that may need to be added to your contacts.
  • Use Do Not Disturb: Combine this feature with ‘Do Not Disturb’ for complete peace and quiet.
  • Stay Informed: Keep your iPhone updated. Apple’s updates often include new features and bug fixes.

If you’re finding your phone constantly buzzing with calls from unfamiliar numbers, implementing this feature can be a game-changer. It’s not just about silencing anonymous callers; it’s about taking back control over your communication. And who knows? You might find that without all the random calls, you have a bit more time to enjoy the things you love. So why not give it a try? With these steps, you’ll be blocking unknown callers like a pro in no time. If you’re curious about other privacy features on your iPhone, don’t hesitate to explore further or seek out additional resources. Your iPhone is packed with features designed to give you a seamless and secure experience.
