Updated List of New USSD Codes for Mobile Operators in Nigeria

The way you access mobile services in Nigeria has changed. Dialing *556# to check your MTN balance or *123# for Glo might no longer respond as expected.

This change came after the NCC decided to scrap network-specific codes and introduce one simplified set that works no matter the SIM you’re using. To buy airtime, check data, or borrow, you’ll now need one code either on MTN, Airtel, Glo, or 9mobile. 

In Lagos traffic, you’ll see people dialing *310# with one hand while flagging down a bus with the other; that’s how essential USSD is.

But using outdated shortcuts can lead to failed attempts. This updated list of new USSD codes saves you time and confusion by showing the exact codes that now work.

Why USSD Codes Changed 

The first goal was to make mobile services easier for everyone to use.

The Nigerian Communications Commission (NCC) replaced the disparate shortcuts used by several networks with one system back in March 2023, though the implementation commenced on May 17th 2023. Back then, checking your balance meant memorizing a different code for every SIM you owned. 

However, as more individuals depended on mobile services for daily necessities and used several lines, the NCC realized it was time to simplify the process.

Besides simplifying things, these new codes now work the same way on every network.

And for millions of users who rely on their phones daily, it’s a big relief that adds ease and better experience.
