How to Disable Private Number on Android and iPhone

If your calls keep showing as “Private Number” or “No Caller ID,” many people may ignore them because hidden numbers are often linked to spam or scam calls. The good news is that you can easily disable private number settings on Android phones, iPhones, and major Nigerian networks like MTN, Airtel, Glo, and 9mobile.

This Zoeeb Guide explains the fastest ways to remove private number settings, show your caller ID again, and fix common issues if the settings are not working properly.

Quick Fix

To disable private number on most phones in Nigeria:

• Dial #31# from your phone
• Or go to your phone’s Caller ID settings and enable “Show Number” or “Show My Caller ID”

If that does not work, follow the device-specific methods below.

Caller ID Settings Guide

Why Your Number Shows as Private

Your phone number may appear as “Private Number” or “No Caller ID” for several reasons:

• Caller ID was disabled in your phone settings
• Your SIM card has a network restriction enabled
• You accidentally activated a hide-number code
• Your network settings failed to update properly

In most cases, the problem can be fixed within a few minutes.

Difference Between Private Number and Unknown Number

Many people confuse “Private Number” with “Unknown Number,” but they are not exactly the same.

A private number usually means the caller intentionally hid their caller ID using phone settings or network codes. In this case, the phone network still recognizes the caller’s number, but it is hidden from the receiver.

An unknown number, on the other hand, often happens because of network issues, international routing problems, or temporary caller ID failures.

USSD Code to Disable Private Number

The easiest method is using a universal USSD code supported by many mobile networks.

Steps to Disable Private Number

1. Open your phone dialer
2. Dial:

#31#

3. Press the call button
4. Wait for the confirmation message
5. Restart your phone if necessary

After this, call another phone to confirm your number is now visible.

This method commonly works on:

• MTN
• Airtel
• Glo
• 9mobile

If the code does not work immediately, try restarting your device or checking your caller ID settings manually.

How to Disable Private Number on MTN

MTN users can disable private number by dialing:

#31#

After dialing the code, restart your phone and test your caller ID by calling another number.

If the issue continues, contact MTN customer support or reset your caller ID settings manually through your phone settings.

How to Disable Private Number on Glo

Glo users experiencing hidden caller ID issues can dial:

#31#

You may also need to restart your phone after activating the code.

How to Disable Private Number on 9mobile

For 9mobile users, the private number setting can usually be disabled using:

#31#

If the issue persists, contact 9mobile customer care for assistance with your SIM settings.

If your number still appears as private, check your phone’s caller ID settings and ensure “Show Number” is enabled.
