Why 9mobile USSD Codes Still Matter
9mobile remains one of Nigeria’s most trusted networks for clarity of calls, balanced data performance, and business-friendly bundles.
Even with growing use of mobile apps, millions of Nigerians still rely on USSD codes to perform quick transactions — from checking balance and borrowing airtime to buying data — especially in places with limited internet access.
This 2025 guide lists all updated, NCC-approved 9mobile USSD codes, explaining how each one works and offering quick fixes for common errors.
Understanding the NCC Code Harmonization
Since the 2023 harmonization, NCC unified all basic telecom codes to reduce user confusion.
That means the same shortcodes now work on all networks, including 9mobile.
| Function | New Code | Old 9mobile Code | Works On |
|---|---|---|---|
| Check Airtime Balance | *310# | *232# | All Networks |
| Recharge | 311PIN# | 222PIN# | All Networks |
| Buy Data | *312# | *200# | All Networks |
| Check Data Balance | *323# | *228# | All Networks |
| Borrow Airtime/Data | *303# | *665# | All Networks |
| Stop Subscriptions | *305# | *227# | All Networks |
| NIN Services | *996# | *200# → NIN | All Networks |
| Customer Care | *300# | *200# | All Networks |
The new system is simpler and ensures every Nigerian can remember just one code set per service.
