What the FNB Service Is Used For
FNB cellphone banking is designed for account tasks that work on any handset, without mobile data. It is most useful when you have signal but no data, when you do not want to use the app, or when you need something quickly.
- Checking balances and recent transactions
- Finding account and reference details
- Buying airtime, data or prepaid electricity
- Making payments and transfers between accounts
- Cash-send and voucher services, where the bank offers them
Not every task is available to every account type or profile. If an option is missing from your menu, it usually means it is not enabled for your account rather than that the code is wrong.
How to Use the Service Safely
- Dial
*120*321#from the cellphone number registered on your FNB account. - Enter your cellphone banking PIN when prompted. This is the PIN you set with the bank, never your card PIN shared with anyone else.
- Read the menu and choose the option that matches what you want to do.
- Confirm the details on screen before you approve anything.
- Wait for the confirmation message and keep it until the transaction reflects.
What you should see next
- A short numbered menu that names FNB or your account
- A prompt for your cellphone banking PIN only
- A confirmation screen showing amounts and recipients before anything is finalised
A genuine session will never ask for your card CVV, your full card number, your online banking password, or an OTP you did not request. End the session immediately if it does.
Available Tasks and Safer Alternatives
USSD is convenient, but it is not always the best channel. For anything large, unusual or disputed, use a channel that leaves a record.
App, website, ATM, branch, or support alternatives
- The official FNB banking app, for full functionality and transaction history
- The official FNB website, for statements and account management
- An ATM, for balances, withdrawals and some transfers
- A branch or agent, for disputes, limits and account changes
- The FNB customer-care line printed on your card or statement
Why the USSD Service May Not Work
- Nothing happens, or you see an invalid MMI code message. Check signal, retry, or restart the handset.
- The session times out. USSD sessions are short. Retry and reply promptly.
- You are dialling from the wrong number. The bank identifies you by the registered cellphone number.
- You are on the wrong SIM. On a dual-SIM handset, select the SIM linked to your account.
- You are not registered. Some banks require a separate registration step before the menu works.
- You are locked out after failed PIN attempts. Contact the bank to reset rather than retrying.

Fees and Limits to Verify
- Whether the USSD session itself is free, and whether that differs by network
- Transaction fees for payments, transfers and cash-send
- Daily and per-transaction limits on your account type
- Whether prepaid purchases carry a separate service charge
- Cut-off times for same-day payments
Fees and limits change. Confirm the current figures with FNB and against your account pricing guide before you rely on them.
Banking Fraud and Privacy Warning
Never share a PIN, password, OTP, or card details
Banking fraud in South Africa frequently starts with a phone call or message that sounds official and creates urgency.
- Never share a PIN, password, OTP, card number or CVV with anyone, including someone claiming to be from FNB.
- No bank asks for those over the phone, by SMS or on WhatsApp.
- Do not use a code you found in an advert, a forum or a social post. Use one from the bank directly.
- Do not let anyone talk you through a session while they are on the line with you.
- If you think you have been compromised, phone the bank on a number you obtained yourself and freeze the account.
