Following the review of USSD commands by the NCC, MTN Nigeria seems to have changed the USSD to check your airtime account balance, alongside providing updates for other commands. The old legendary MTN USSD – *556#, is no longer responding as usual. We’ll now show you the new code to check your account balance.

When you dial the *556# command, you get a prompt that says your dial was wrong and that you should choose from a list of 7 items what command you intended. The image below shows the details of the prompt:

Therefore, to check your airtime account balance through the prompt, you’ll need to enter the number 4. And as ofat today 17, May 2023, directly check your MTN airtime balance with USSD, you may have to dial the new USSD *310#.

Currently, the commands listed 1-7 on the pop-up are the new direct USSD for those services listed beside them. However, their initial access codes are still working.
