MTN Loyalty Points USSD Code

Last Verified: July 2026

Quick Answer

The official MTN Loyalty Points USSD code for MTN South Africa is *234#. Dialling this code opens the MyMTN YelloBucks menu, where you can register your profile, check your points balance, play the daily game for free prizes, and redeem your earned YelloBucks for airtime, data, or retail vouchers.

Alternatively, you can access the YelloBucks loyalty portal through the main MTN self-service USSD menu by dialling *135# and selecting Option 5 (YelloBucks).

Common Problems and Troubleshooting

Code, Session, SIM, or Account Errors

• “Connection Problem or Invalid MMI Code”:
  • Cause: Intermittent signal loss or standard network timeout.
  • Fix: Verify you have signal bars, toggle Airplane Mode on and off, and re-dial *234#.
• “User Profile Not Found / Registration Required”:
  • Cause: Points are not tracked until you formally activate your YelloBucks membership.
  • Fix: Complete the one-time registration prompt via *234# or use the official MTN App.
• “Insufficient YelloBucks Balance”:
  • Cause: You do not have enough points to complete the selected bundle redemption.
  • Fix: Check your balance first to ensure you meet the minimum required points for the product.

When the Service Has Changed or Is Unavailable

• Network Service Outages: During scheduled maintenance, USSD sessions may drop. Wait 15 to 30 minutes before trying again.
• Unallocated Points: If you made a qualifying recharge or contract payment but points do not reflect, allow up to 24 hours for billing systems to reconcile.

Official Alternatives

When the USSD service is unresponsive or timed out, use these official MTN channels:

• Official MTN App (Zero-Rated): Download or open the MTN App on Android/iOS. Navigate to the YelloBucksapplet to check balances, register, play the daily game, and spend points. Browsing the MTN App is zero-rated and does not use active mobile data.
• MTN WhatsApp Self-Service: Message “Hi” to MTN Chat on WhatsApp (083 123 0011) to manage basic account services.
• Customer Support: Call 135 (Free from an MTN SIM) or visit an official MTN Retail Store for account disputes or missing-points investigations.

Safety and Privacy

Security Warning: MTN will never ask for your SIM PIN, Mobile Money (MoMo) PIN, one-time PINs (OTPs), or online banking passwords to check or credit your loyalty points.

The main USSD code is *234#. You can also access loyalty settings through the main MTN menu by dialling *135# and selecting Option 5.

How can points be checked?

Dial *234# and select the Balance option. You can also log into the free MTN App and view your YelloBucks dashboard on the home screen.

How are rewards earned?

You automatically earn 1 YelloBuck for every R1 spent on airtime recharges, bundle purchases, or active monthly contract subscriptions. You can also win bonus points through the daily Play & Win game.

Do points expire?

Yes. YelloBucks expire after 365 days if unused. Additionally, accounts with no redemption activity for 60 consecutive days incur a 150 YelloBucks monthly maintenance deduction until activity resumes.

What should I do if the MTN USSD route does not work?

If dialling *234# fails or times out, open the zero-rated MTN App on your device to manage your rewards directly. Alternatively, contact MTN Support by dialling 135.
