Safety and Privacy
- What a real check never asks for: An MTN USSD balance check will never want your SIM PIN, banking PIN, internet password, or ID number. Displaying a balance needs none of them.
- Third-party fraud: Do not dial long unfamiliar codes arriving by SMS and promising free airtime or “double balance bonuses”.
- Reporting: For suspicious prompts or unexplained subscription charges, dial
*135#or call MTN Customer Care on 135.
Frequently Asked Questions
What is the MTN balance code?
The verified USSD code is *136#, which shows your remaining airtime. *136*1# opens the detailed voice and data bundle breakdown.
Which balance does the code show?
*136# gives your prepaid rand airtime credit. *136*1# or the *135# menu adds the secondary balances: daily and monthly data, night express data, promotional voice minutes, and SMS bundles.
Must I dial from the number I am checking?
Yes. The query is tied to the SIM making the call, so it has to be dialled from the MTN SIM whose balance you want.
Is the amount real-time or delayed?
Airtime and ordinary data usage update almost instantly. Heavy data use during a live session can take a few minutes to reconcile once that session closes.
What should I do if the MTN USSD route does not work?
Try *135# as the secondary option, check balances in the free MyMTN app, or message “Balance” to MTN on WhatsApp at 083 123 0011.
