How to Block Private Number Calls on MTN Line

Receiving calls from private numbers can be frustrating and sometimes even stressful. Many people use private numbers to hide their identity, and in most cases, these calls are spam, marketing, or even harassment. If you’re an MTN user in Nigeria, you might have asked yourself: “How can I block private number calls on my MTN line?”

In this guide, I’ll walk you through practical methods to block private number calls on your MTN line, improve your peace of mind, and enjoy a stress-free mobile experience.

Why People Use Private Numbers

Before diving into the solution, it’s important to understand why some callers hide their numbers:

Telemarketers often mask their numbers to avoid being blocked.
Scammers use private numbers to trick unsuspecting victims.
Friends or acquaintances may hide their identity just to prank you.
Harassment — Some people deliberately use private numbers to disturb others.

Regardless of the reason, blocking these calls is the best way to stay in control of your phone.

Can You Block Private Number Calls on MTN?

Yes, but here’s the thing: MTN itself doesn’t offer a direct “block private numbers” USSD code or setting. However, there are reliable ways to block private number calls using:

Let’s break down each option.

Method 1: Using Phone Settings

Most modern smartphones (Android and iPhone) allow you to block private numbers without using any third-party apps.

On Android:

Open the Phone/Dialer app.
Tap on the Menu (three dots or settings icon).
Go to Call Settings → Block Numbers.
Toggle on “Block Unknown/Private Numbers”.

Once this is enabled, your phone will automatically reject all private number calls.

On iPhone:

Go to Settings.
Tap Phone → Silence Unknown Callers.
Toggle it ON.

This feature will silence or block calls from private and unknown numbers.

If your phone doesn’t support direct blocking of private numbers, you can use call-blocking apps. Popular apps include:

Truecaller (available on Google Play Store and App Store)
Call Blocker
Hiya

These apps let you block hidden numbers, spam calls, and even blacklist specific numbers.

Method 3: Contacting MTN Customer Care

In cases of persistent harassment, you can contact MTN directly for assistance:

Dial 300 (MTN Customer Care line).
Explain that you’re receiving private number calls and request possible solutions.
They may advise you to use device settings or escalate your complaint.

Extra Tips to Stay Protected

Avoid picking calls from numbers you don’t recognize.
Always keep your Truecaller app updated to detect spam calls.
If harassment continues, consider reporting to authorities.
