If you recently tried to check your airtime with *556# or buy data with *131# and received an error, you are not alone. As of 2025, the Nigerian Communications Commission (NCC) has fully implemented the Harmonized Short Codes directive. This means all mobile networks in Nigeria MTN, Airtel, Glo, and 9mobile now use the exact same codes for the same services.
This change was designed to stop the “memory tax” of learning different codes for every SIM card you own. Whether you are using a brand new Samsung A16 or a reliable feature phone, these updated MTN USSD codes are now your universal keys to managing your account.
In this guide, I will show you the new MTN recharge code, how to check your data balance instantly, and the unified code for linking your NIN. If you want to save time, use the interactive “One-Tap” tables below to copy the codes directly to your phone.
The Most Important New Codes at a Glance
- Check Balance: *310#
- Buy Data: *312#
- Recharge: *311#
