Official Direct USSD Code: There is no single, standalone direct USSD shortcode operated directly by OTT Mobile Technologies.
An OTT Voucher is a 12-digit digital cash PIN that works across many platforms, so no central shortcode sits behind it. You reach OTT Voucher services through a partner’s USSD menu instead, and which menu you dial depends on whether you are buying or redeeming:
- To buy an OTT Voucher via Mobile Banking USSD: Dial
*120*3279#(Capitec) or*120*2345#(Standard Bank). - To redeem an OTT Voucher for airtime/data top-up via mobile network: Dial
*136#(or*136*0*voucherPIN#) on supported mobile networks/MVNOs.
For non-USSD access or data-free web management, use the official ottvoucher.com portal or MoyaApp.
What an OTT Voucher Is and Who Can Use It
An OTT Voucher is a prepaid digital cash voucher issued as a 12-digit PIN. It lets unbanked and cash-first consumers in South Africa turn physical cash into digital value. That value pays for online purchases, funds gaming and betting accounts such as Betway and Hollywoodbets, settles utility bills through Pay@, buys airtime and data, or covers lay-bys and insurance, all without a credit or debit card.
Who Can Use It
- Prepaid Mobile Subscribers: Customers on Vodacom, MTN, Cell C, Telkom, and partner MVNOs looking to redeem airtime or data using an OTT Voucher PIN.
- Mobile Banking Clients: Account holders with access to Capitec or Standard Bank cellphone banking.
- Cash Consumers: Anyone who buys a physical 12-digit PIN slip from retail chains (Shoprite, Checkers, Pick n Pay, Boxer) or informal spaza shops using Kazang, A2Pay, or Pav Telecoms.
How to Access the Service
Before You Start
- Have your PIN or banking details ready: If redeeming, keep your 12-digit PIN slip visible. If purchasing, ensure your bank account has sufficient funds.
- Use the registered SIM card: Dial from the number linked to your cellphone banking profile when buying through a bank USSD menu.
- Maintain strong signal: USSD sessions need continuous cellular connectivity or they time out.

Common Problems and Troubleshooting
Code, Session, SIM, or Account Errors
- “Connection Problem or Invalid MMI Code”: Signal instability or heavy network congestion. Wait a moment, check your connection, and dial again.
- “Session Timed Out”: USSD sessions drop after 20 seconds of inactivity. Redial the shortcode and answer each prompt quickly.
- “Invalid Voucher PIN”: Check that all 12 digits went in correctly, and make sure you are not holding a different product. An OTT Voucher is not a Blu Voucher or a 1Voucher PIN, and the PINs are not interchangeable.
- “Insufficient Balance”: When buying through cellphone banking, your balance must cover the voucher amount and the R1 to R3 USSD service fee.
When the Service Has Changed or Is Unavailable
Carrier downtime or banking USSD maintenance can interrupt access. If the USSD channel keeps failing, do not fire off repeated duplicate attempts, because each one can carry a fee. Switch to an official alternative channel instead.
Official Alternatives
If USSD services are unavailable or timing out, use these official methods:
- Official Website Portal: Visit ottvoucher.com to buy vouchers online, redeem services, or locate nearby stockists.
- MoyaApp (Data-Free): Download MoyaApp to buy and redeem OTT Vouchers without using active mobile data.
- Over-the-Counter Retailers: Buy physical voucher slips with cash at Shoprite, Checkers, Pick n Pay, Boxer, Makro, Shell, Engen, or local spaza vendors using Kazang, A2Pay, or Pav Telecoms.
- Merchant Direct Deposit: To fund accounts on platforms such as Betway, Hollywoodbets, or Pay@, log into the merchant’s own portal, select OTT Voucher as the payment method, and enter the 12-digit PIN.
- Related Payment Guides: Browse the full Payment USSD Codes hub, or compare transfer routes in Send Money USSD Codes.
Safety and Privacy
- Protect Your 12-Digit PIN: Treat the PIN like cash. Anyone who sees it can redeem the full value instantly, and there is no card to cancel afterwards.
- Never Share Credentials: Neither OTT Mobile Technologies nor any bank will ask for your Mobile Banking PIN, OTP, or account password by phone or on social media.
- Beware of Voucher Scams: Reject anyone offering to “double” or “verify” your voucher PIN. Both are straightforward theft.
- Immediate Disconnection: End any session where a menu, message, or caller asks for credentials the service does not legitimately need.
Frequently Asked Questions
What is the current OTT USSD Code?
There is no single direct USSD shortcode for OTT. You reach OTT Voucher services through bank menus, such as Capitec’s *120*3279# or Standard Bank’s *120*2345#, to buy vouchers, or through network top-up menus such as *136# to redeem airtime.
How do I use an OTT voucher to buy airtime?
Dial *136# on a supported network, choose Redeem Voucher, and enter the 12-digit PIN. You can also dial the full string *136*0*voucherPIN# in one go.
Which customers or account types can use it?
Any mobile user on a South African network (Vodacom, MTN, Cell C, Telkom, or supported MVNOs), plus active mobile banking account holders, can reach OTT Voucher services via USSD.
How long is an OTT voucher valid?
Three years, or 36 months, from the date of issue. Keep the slip or the SMS until you have spent the full value, because partial balances stay on the same PIN.
What should I do if the OTT USSD route does not work?
Check your signal and try once more. If it stays unavailable, buy or redeem through the data-free MoyaApp, the ottvoucher.com website, or an authorised retail agent.
