Why Hide Your Number?

There are numerous reasons why someone might want to hide their number on MTN:

Understanding Caller ID Blocking Services

Before diving into the methods, let’s clarify what “hiding your number” actually means. MTN offers various services and techniques that achieve this, but it’s crucial to understand their limitations:

  • You hide your caller ID, not your entire identity. The recipient might still be able to identify you through other means, like call logs or caller ID apps.
  • These services don’t prevent your call from being tracked or recorded. MTN, law enforcement, or other authorized entities might still have access to call data.

Methods How to Hide Number on MTN for Making Calls

MTN offers various ways to hide your number, each with its own advantages and limitations.

The Mighty USSD Code to Hide Your MTN Number: #31#

The simplest and most common method is the #31# code. Here’s how it works:

  • Dial #31#phone number. For example, dial #31#0812345678 and press call.
  • Your MTN number will only be hidden for that call. But it won’t stay hidden forever.
  • It’s free and readily available, making it a convenient choice for occasional use.


  • Temporary: Requires redialing the code for each call.
  • Not foolproof: Some caller ID apps might still display your number.

Calling Forwarding Magic: Diverting Calls with Hidden Identity

Want to hide your number for all incoming calls but still receive them? Consider call forwarding with caller ID blocking:

  • Activate call forwarding on your MTN line. Dial *21*desired forwarding number# and press send. This diverts all calls to the chosen number.
  • Enable caller ID blocking on the forwarding number. This hides your original number when the forwarded call connects.
  • Turn off call forwarding when you’re done using it. Dial ##21# and press send.


  • Requires setting up and managing two separate numbers.
  • Might incur charges depending on your call forwarding plan.

Prepaid Magic: Dedicated SIM Cards for Discretion

For ultimate privacy, consider a dedicated MTN SIM card solely for making hidden calls:

  • Purchase a new MTN SIM card specifically for this purpose.
  • Activate and recharge the SIM card as needed.
  • Use the #31# code or other methods to hide your number on this dedicated line.


  • Requires additional cost for the SIM card and recharge.
  • Managing multiple SIM cards can be inconvenient.

App Avenue: Exploring Third-Party Caller ID Masking Apps

Several third-party apps offer caller ID masking functionalities:

  • Popular options include Truecaller, Should I Answer, and Burner.
  • Features vary by app, including one-time masking, permanent blocking, and even virtual phone numbers.
  • Carefully review app permissions and privacy policies before using.


  • Apps require installation and may consume data.
  • Security and privacy concerns around data collection and usage exist.

How to Hide Number on MTN to Send Message on Android

While directly hiding your phone number when sending a message on MTN (or any other network in Nigeria) isn’t possible using an Android phone, here are some alternatives:

1. Third-Party Messaging Apps:

  • Telegram: This app allows creating “Secret Chats” with end-to-end encryption and the option to set a self-destruct timer for messages. However, the recipient still needs a Telegram account to interact with you.
  • Signal: Similar to Telegram, Signal offers end-to-end encryption and the ability to set disappearing messages. It prioritizes user privacy and doesn’t collect user data, making it a secure option. However, both you and the recipient need Signal accounts to use the service.

2. Temporary Phone Numbers:

Some online services provide temporary phone numbers you can use to send text messages anonymously. These numbers are usually active for a limited time and cannot be used for receiving messages. However, be aware that these services often come with charges, and their reliability can vary.

3. Online SMS Services:

Websites like and allow sending text messages online. You can use a temporary email address to create an account and send messages anonymously. However, these services might have limitations like character restrictions or daily sending limits, and their security might not be as robust as dedicated messaging apps.

Important Considerations:

  • Legality: Before using any method to send anonymous messages, ensure it complies with local laws and regulations. Using these methods for illegal activities can have serious consequences.
  • Privacy: While these options offer some level of anonymity, they might not be foolproof. The recipient might be able to trace your identity through IP address or other means, especially if they suspect something is amiss.
