How to Check Airtime And Data Balance On MTN, Airtel, GLO, & 9Mobile

Do you need help checking your airtime and data balances? Maybe you no longer remember the codes, or they have refused to work.
Well, the codes have likely been changed. In 2023, the Nigerian Communications Commission (NCC) directed all Telecos to harmonise their USSD code. That way, everyone uses the same code to check Airtime and data balances.
In this article, I will update you on the latest ways to check your airtime, data balances, and related services across any network in Nigeria.
Balance Check Codes for All Networks in Nigeria
| Action | Code to Dial |
| Check Airtime Balance | *310# |
| Check Data Balance | *323# |
| Buy Data | *312# |
| Recharge Airtime | *311*PIN# |
| Borrow airtime | *303# |
| Share Airtime or Data | *321# |
As earlier stated, these codes work the same on MTN, Airtel, Glo and 9mobile due to the NCC harmonization that occurred in 2023. If you want network specific methods, see the sections below.
