Nigeria USSD Codes 2026: MNO Reference and B2B Fintech Guide

USSD (Unstructured Supplementary Service Data) codes are short numeric strings starting with an asterisk and ending with a hash symbol that let any phone (smartphone or feature phone) talk to a network or business application without internet. In Nigeria in 2026, USSD remains the backbone of mobile banking, airtime top-up, data bundling, bill payments, and fintech onboarding for a market that the Nigerian Communications Commission (NCC) reports at over 220 million active mobile lines.

This guide gives you the consumer answer fast (the codes for MTN, Airtel, Glo, 9mobile, banks, and fintechs) and then pivots to the buyer angle: how Nigerian fintechs and SMBs deploy USSD shortcodes commercially in 2026, what the regulatory landscape looks like under the NCC, what the market is worth, and how HelloDuty positions to help businesses launching USSD services in Nigeria.

The quick consumer reference: Nigeria USSD codes in 2026

Following the NCC's harmonisation directive, the four major mobile network operators in Nigeria use unified codes for core services:

• MTN Nigeria — Airtime balance: *310#. Borrow airtime (XtraTime): *303#. Data purchase: *312#. Check data balance: *323#. Recharge: *311*PIN#.
• Airtel Nigeria — Same unified codes (*310#, *303#, *312#, *323#, *311*PIN#). Network-specific menu: *121#.
• Glo — Same unified codes. Network menu: *777#.
• 9mobile — Same unified codes. Network menu: *200#.

To use any of these, open your phone dialer, key in the code starting with an asterisk and ending with a hash, press call, and follow the on-screen menu. No data, no app, no smartphone required.

Common troubleshooting

• Weak signal. USSD requires a stable SS7 signalling path; move to better coverage and retry.
• Service timeout. Operator gateways occasionally throttle under load; wait a few minutes and retry.
• Wrong code. Double-check the asterisk and hash. Some codes have changed under the NCC harmonisation; the unified codes above are current as of 2026.

For airtime recharge across all four major MNOs in 2026, dial *311*PIN#. To reach customer care, dial 300 (no asterisk or hash, also harmonised under NCC).

That is the consumer reference. Now for the buyer angle.

Why Nigerian USSD is a multi-billion-naira B2B opportunity

USSD in Nigeria is not a fallback technology. It is a strategic distribution channel. Per the NIBSS Instant Payments report, USSD-initiated banking transactions in Nigeria crossed NGN 6 trillion annually by 2024 and have continued growing as fintechs onboard the unbanked. The Central Bank of Nigeria (CBN) estimates that USSD remains the single most-used digital banking channel after mobile apps, with hundreds of millions of monthly sessions across all banks and fintechs.

Three things make USSD strategically critical for any business serving Nigeria:

• Reach. USSD works on every phone, on every network, in every region, including areas with poor data connectivity.
• Cost. USSD sessions cost a fraction of internet-based equivalents and require no app install or update.
• Conversion. USSD funnels have higher completion rates than mobile-web forms for low-value, high-frequency transactions (loan top-up, airtime, bill pay).

That is why every Nigerian fintech (OPay, PalmPay, Moniepoint, Carbon, FairMoney) treats USSD as a primary channel, why every bank pays significant fees for shortcode allocation, and why a new wave of B2B SMBs (retail, agritech, microinsurance, logistics) is now launching USSD services to reach the next 100 million Nigerian consumers.

How Nigerian fintechs and SMBs use USSD commercially

Mobile money and microfinance

OPay, PalmPay, and Moniepoint use USSD as the entry point for account creation, KYC capture, wallet funding, and inter-wallet transfer. A user without a smartphone can open a wallet in under three minutes by dialling a USSD code and entering BVN details. This is the core unlock for financial inclusion in Nigeria.

Microcredit and BNPL

Lenders like Carbon and FairMoney use USSD to disburse and recover micro-loans. The session keys off the borrower's phone number, checks credit history via bureau APIs, and pushes funds to the linked bank account, all in 30 seconds.

Microinsurance

Health and crop-insurance products targeting smallholder farmers in northern Nigeria are sold and serviced almost entirely over USSD. Subscribers dial in, choose a plan, pay via airtime deduction or wallet, and receive policy SMS confirmations.

Loyalty and trade marketing

FMCG distributors (Nigerian Breweries, Unilever, PZ Cussons) run trade-marketing programs where retailers dial a USSD shortcode after scanning a pack code to redeem points. This lets brands incentivise the long tail of small retailers who do not have smartphones.

Agriculture and logistics

Agritech platforms use USSD for input ordering, price discovery, and farmer registration. Logistics aggregators use USSD for driver onboarding and trip confirmation across regions with weak data coverage.

Voting, surveys, and engagement campaigns

Telcos and media houses run mass-engagement USSD campaigns (vote for X, register for Y) that reach tens of millions of subscribers in a single window.

The NCC regulatory landscape for USSD in 2026

To launch a commercial USSD service in Nigeria you must navigate three regulatory layers:

• NCC shortcode allocation. The Nigerian Communications Commission allocates and supervises USSD shortcodes. Banks and fintechs typically secure a 4-digit dedicated shortcode (e.g., *901#). SMBs and developers usually start with a shared aggregator shortcode subdivided by sub-codes (e.g., *347*XYZ#).
• End-user billing. Following NCC and CBN guidance, MNOs charge end users for USSD sessions on a per-session, fixed-fee basis (typically NGN 6.98 per 20-second session for banking transactions). The agreement between banks and MNOs on this fee has been historically contentious; the current end-user-pays model is in force across all four MNOs.
• Compliance. CBN guidelines apply for any USSD service involving payments or financial accounts. Data Protection Regulation (NDPR/NDPA) requirements apply for personal data captured in sessions.

This regulatory complexity is precisely why most Nigerian businesses launching USSD use an aggregator rather than negotiating with each MNO directly.

Market sizing: the Nigerian USSD opportunity

Pulling together public data points:

• Over 220 million active mobile lines in Nigeria (NCC, 2026).
• Over 6 trillion naira in annual USSD-initiated banking value (NIBSS).
• An estimated 40-45% of Nigerian banking customers use USSD at least monthly.
• USSD-led fintechs like OPay, PalmPay, and Moniepoint each processing billions of naira monthly.

For any B2B vendor selling into Nigerian fintech, insurance, FMCG, agritech, or telco verticals, USSD is not optional. It is the access layer to the mass market.

How a fintech actually picks a USSD aggregator in Nigeria

If you sit on the procurement side of a Nigerian fintech, microfinance bank, insurer, FMCG, or agritech, the USSD aggregator evaluation typically comes down to seven criteria. First, MNO coverage and parity: does the aggregator serve all four major MNOs (MTN, Airtel, Glo, 9mobile) and route to them with comparable latency? Second, session latency and reliability: USSD sessions are typically capped at 120 seconds end-to-end; an aggregator that adds 600ms of round-trip latency burns a third of your menu budget. Third, shortcode availability: can they secure a memorable 4-digit code or do you have to launch on a long sub-code? Fourth, pricing model: flat per-session, revenue-share with the MNO, or hybrid? Fifth, compliance posture: do they map cleanly to CBN payment-services regulation and the Nigerian Data Protection Act? Sixth, developer experience: webhook-based session handling, sandbox, SDKs, and observability. Seventh, support and incident response: who answers the phone when *901# stops working on a Saturday at 11pm? HelloDuty designs against all seven from day one.

USSD vs WhatsApp vs SMS for Nigerian businesses

A common buyer question: which channel should I prioritise? Here is the practical framing:

• USSD wins when the customer is on a feature phone, in a low-data area, or doing a transactional flow under 60 seconds (balance check, top-up, mini-loan, vote).
• WhatsApp wins when the customer is a smartphone user, the interaction is conversational, and rich media matters. See our take on upgrading from the WhatsApp Business app to the API.
• SMS wins when you need one-way reach to the largest possible audience (OTPs, broadcasts, reminders).

The right answer for most Nigerian B2C-at-scale businesses is all three, orchestrated from one customer record. HelloDuty provides that orchestration.

Frequently asked questions

What is the USSD code for airtime recharge in Nigeria?

Following NCC harmonisation, dial *311*PIN# on MTN, Airtel, Glo, and 9mobile.

What is the USSD code for transferring money in Nigeria?

Each bank has its own: GTBank *737#, Access Bank *901#, First Bank *894#, UBA *919#, Zenith *966#, and so on. Follow the on-screen prompts after dialling.

How do I check my data balance in Nigeria?

Dial *323# on any of the four major MNOs.

How do I pay an electricity bill via USSD in Nigeria?

Use your bank's USSD (e.g., *737*1*amount*meter# on GTBank) or the unified bills service code provided by your bank. Follow the on-screen prompts.

How much does it cost to launch a USSD service in Nigeria?

Dedicated 4-digit shortcodes cost millions of naira annually directly with MNOs. Aggregator-based shared shortcodes are accessible from a few hundred thousand naira per month, with per-session fees. HelloDuty can scope a deployment cost for your use case.

Do I need NCC approval to run a USSD service?

Yes for dedicated shortcodes. Aggregator-routed services typically inherit the aggregator's licensing. CBN and NDPA compliance apply separately for fintech and personal-data use cases.

What is the difference between USSD and SMS for businesses?

USSD is interactive and session-based (menu navigation, transactions); SMS is one-way and store-and-forward (notifications, OTPs). They complement each other.

Is USSD still relevant in 2026?

Absolutely. With over 220 million Nigerian mobile lines and a significant share of users on feature phones or in low-data regions, USSD remains the most reliable digital channel for mass-market financial and commercial services.

What are the leading USSD aggregators in Nigeria?

The market includes Africa's Talking, Termii, HelloDuty, and direct telco partnerships. Selection depends on shortcode availability, pricing, latency, and integration support. For comparison see USSD providers in the region.

The bottom line

USSD is the access layer to mass-market Nigeria. The consumer-grade reference list of codes for MTN, Airtel, Glo, 9mobile, and the major banks and fintechs is essential to know, but the real opportunity in 2026 is on the buyer side: B2B vendors, fintechs, FMCGs, insurers, and agritechs all need USSD as part of their distribution stack. The winners are the businesses that pair USSD with SMS, WhatsApp Business API, and voice, orchestrated from one platform.
