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

April 28, 2025 By Steven

If you’ve ever been annoyed by unknown callers interrupting your day, you’re not alone. Fortunately, blocking these pesky unknown callers on your iPhone is easier than you might think. All it takes is a few taps in your settings, and voilà, unwanted calls will go straight to voicemail. In just a couple of minutes, you can have peace of mind knowing that your phone won’t buzz unexpectedly from unknown numbers. Let’s get started!

How to Block Unknown Callers on iPhone

Blocking unknown callers on your iPhone will ensure that calls from numbers not in your contacts, and without caller ID, are sent directly to voicemail. This feature is perfect for avoiding those unwanted disturbances.

Step 1: Go to Settings

Open the Settings app on your iPhone.

In the Settings app, you’ll find various options to customize your iPhone experience. It’s like the control center for your device. So, let’s dive in and find the right setting to block those unknown calls.

Step 2: Scroll Down to Phone

Look for and tap on the "Phone" option.

The Phone settings section might remind you of a phone book, but it’s where you can manage your call preferences. Here, you’ll find features related to calls, like call forwarding and call blocking.

Step 3: Tap on Silence Unknown Callers

Find and select the "Silence Unknown Callers" option.

This feature is the magic button that keeps unwanted calls at bay. By enabling it, only calls from your contacts and recent outgoing calls will ring your phone. Unknown calls will go straight to voicemail.

Step 4: Toggle the Switch to On

Turn on the switch next to "Silence Unknown Callers."

Once you activate this feature, your phone will automatically handle unknown calls by sending them to voicemail. This means you can continue your day without disruptions from unknown numbers.

Step 5: Confirm the Setting

Make sure the switch is green, indicating it’s active.

A green switch is your green light to a quieter phone experience. Now, you’re all set, and unknown callers will no longer interrupt your peace.

Once you complete these steps, your iPhone will automatically send calls from unknown numbers to voicemail. You won’t hear a ring, and the call won’t appear in your missed calls list. Instead, it’ll show up in your voicemail if the caller leaves a message, allowing you to screen it later.

Tips for Blocking Unknown Callers on iPhone

  • Keep Your Contacts Updated: Ensure that you save important numbers in your contacts so they aren’t mistakenly silenced.
  • Review Voicemail Regularly: Since unknown callers go to voicemail, check your messages to avoid missing important calls.
  • Be Cautious with Unknown Numbers: Not all unknown calls are bad. Some might be important, so consider leaving a message requesting a callback.
  • Use Do Not Disturb: For an extra layer of quiet, use Do Not Disturb mode during specific hours.
  • Educate Family and Friends: Let them know about this feature, so they can benefit from it too.
