Wetin be MCC 7995 and 7993 (and why e concern your betting money)
Every merchant wey accept card payment get a Merchant Category Code (MCC) — a four-digit number wey tell card networks wetin kind of business dem be. When you swipe or enter your card details online, your bank no just see “money dey go somewhere.” E see exactly wey category that merchant fall under. MCC 7995 cover betting, gambling, lottery, and wagering; MCC 7993 cover amusement arcades, VLT machines, and electronic gaming establishments. Banks and card issuers fit use these codes to approve or decline a payment category — before money ever reach any platform.
Dis na the same mechanism wey don already lead GTBank, Access Bank, Zenith, UBA, First Bank, Wema, FCMB, Stanbic IBTC, and Kuda to block international Mastercard and Visa from processing MCC 7995 transactions for most customers. The challenge na say Verve (local Interswitch) debit cards operate on domestic rails where this filter no always apply the same way, and mobile wallet transfers — OPay, PalmPay, Moniepoint — dey outside the bank card system entirely.
MCC 7995 vs 7993 — wetin dem cover
| Code | Category | Nigerian examples | Coverage note |
|---|---|---|---|
| 7995 | Betting, Gambling, Lottery, Wagering | SportyBet, Bet9ja, BetKing, MSport, 1xBet, online casino platforms | Primary code for most NG betting and casino platforms wey accept card payment |
| 7993 | VLT / Amusement arcades, electronic gaming | Physical gaming centres, some online slots platforms | Less common for online-only operators; most relevant for physical betting shops wey accept card |
One limitation worth knowing: some offshore operators deliberately tag demself under a neutral MCC — a general “retail” or “services” code — specifically to bypass bank-level blocks. A block on 7995 and 7993 na a strong barrier, not a perfect one. Na why this guide dey recommend stacking every layer, not relying on the bank call alone.
Why Nigerian banks no get one-tap gambling block yet (May 2026 reality)
The question I hear from many readers na this: “Why can’t I just flip a switch in my app the way Monzo people dey do am?” It is a fair question — and the honest answer na that Nigerian banking infrastructure, while highly capable for transfers and payments, no been built the in-app category-level toggle controls that UK challengers launched as a differentiating feature. As of May 2026, no Nigerian bank has released a self-service MCC gambling block inside their mobile app.
This gap no be trivial. The data from the Nigerian payment landscape show that international Mastercard and Visa are already blanket-blocked at MCC 7995 by the nine major banks named above — so that specific leak don close for most customers on those card types. The active leaks wey still dey open are: Verve cards wey operate on local rails; card details already saved on betting platforms before the bank block was applied; USSD deposit shortcodes wey bypass card infrastructure entirely; and mobile wallet funding through OPay, PalmPay, and Moniepoint. Understanding this map of vulnerabilities na where effective self-protection starts.
How to call your bank make dem block gambling MCC for your card
The call-and-request method na the foundation of everything else in this guide — it closes the bank card layer formally, creates a paper trail, and sets up the conditions where the other layers can reinforce each other. Follow these steps precisely.
- Gather your account details before you call: Have your BVN, account number, the last four digits of your card, and a valid ID ready. The agent go verify your identity before making any changes.
- Use only the official bank contact channel: Call the number printed on the back of your card or listed on the bank’s official website. Never use a contact number from a random SMS, WhatsApp message, or Google ad result.
- State your request specifically: Tell the agent: “I want to block all gambling and betting transactions on my card and account — specifically Merchant Category Codes 7995 and 7993. I am requesting this voluntarily for self-protection purposes.” Using the exact MCC numbers go help the agent understand and process the request correctly without confusion.
- Request a reference or ticket number: Before you end the call, ask for a reference number. If the block no activate properly, this ticket go be your evidence when you follow up.
- Request written confirmation: Ask them to send you an SMS or email confirming that the restriction has been applied to your account.
- Test the block: Attempt a small deposit on a betting platform — ₦100 or the minimum allowed — and confirm that the transaction declines. If e still goes through, call back, quote your ticket number, and escalate to a supervisor.
GTBank, Access, Zenith, UBA, First Bank
These five banks carry the largest share of Nigerian debit card transactions. International Mastercard and Visa are already largely blocked on MCC 7995 for their customers, but a formal call request for Verve cards and for a specific account-level restriction is still worth making. Use these official contact channels:
| Bank | Customer care line | USSD (self-service banking) | App channel |
|---|---|---|---|
| GTBank | 0700 000 0480 | *737# | GTWorld app live chat |
| Access Bank | 01 2802 900 | *901# | AccessMore app chat |
| Zenith Bank | 0700 936484265 | *966# | Zenith Mobile app |
| UBA | 07002255822 | *919# | UBA app / Leo chatbot |
| First Bank | 01 4485500 | *894# | FirstMobile app |
Important note: the USSD codes listed above are for general self-service banking — balance checks, transfers, and limit changes. Dem no provide a direct MCC gambling block by themselves. You still need to speak with a live agent to get the specific 7995/7993 restriction applied to your account.
Wema Bank (ALAT), FCMB, Stanbic IBTC, Kuda
Wema, FCMB, and Stanbic IBTC have already applied international card blocks on MCC 7995 at the network level. To request a formal account-level restriction or to address Verve card transactions, call their official customer care lines or visit a branch using the same six-step procedure above. Kuda and ALAT (Wema’s digital brand) offer more granular in-app card controls than most traditional banks — you fit freeze your card, disable online transactions, or explore card-control settings directly inside the app under “Card Settings” or “Security.” Start there before calling support.
How to comot your saved cards from every betting site
Here na the most commonly overlooked gap — and the most dangerous one. Even after your bank applies the MCC block, any card details you saved on a betting platform before the block was in place remain active. Some stored credential flows bypass a fresh MCC authorisation check, meaning the platform fit still attempt to process deposits against that saved card.
The fix na direct: log into every betting account you hold, navigate to Account Settings or Wallet or Payment Methods, and delete every saved card entry. Do am for every platform wey you dey registered on — SportyBet, Bet9ja, BetKing, MSport, betPawa, 1xBet, and any others. After that, check your browser autofill settings (Chrome, Firefox, and Safari all store card data under Settings or Passwords), your phone’s digital wallet (Google Pay, etc.), and any third-party autofill managers you installed. Card details stored anywhere na a temptation the next time you dey under pressure — remove every copy.
Opt out of international transactions and reduce your daily limit
Offshore betting platforms — operators wey no hold a Nigerian state licence from LSLGA, FSGRN URC, or another state authority — typically process card payments as international transactions routed through foreign card acquirers. Disabling international transactions on your card creates a second-layer block that catches what the MCC filter misses when operators route through non-standard channels.
Most Nigerian banks allow you to toggle international card transactions off via the mobile app (check under “Card Settings,” “Card Controls,” or “Manage Card”) or by calling customer care. When you make this request, specify clearly: “I want to disable card-not-present international transactions and online international purchases on my card.”
Reduce daily limit by USSD / app
A complementary friction measure na to reduce your daily card transaction limit to below a typical betting top-up amount. If your impulsive wager na usually ₦5,000 or more, setting your daily card limit to ₦2,000 caps the maximum damage from a lapse even if another layer temporarily fails. Most banking apps allow limit changes under “Transaction Limits,” “Daily Limit,” or similar settings; the exact floor and ceiling vary by bank, and the agent or app will tell you the available range. Changes typically take effect within hours. Stack this with the MCC block and the international transaction disable — dem reinforce each other.
How to off USSD payment shortcodes wey betting site dey use
USSD na one of the most powerful and underappreciated deposit rails in Nigeria — and one of the hardest to block, because e no require internet and e go work directly from any SIM. GTBank’s *737#, First Bank’s *894#, Zenith’s *966#, Access Bank’s *901#, and UBA’s *919# all dey allow deposits directly to betting platforms: minimum ₦50, maximum ₦200,000 per transaction. The speed of a USSD top-up — five seconds from impulse to funded betting account — makes it one of the highest-risk funding channels for anyone wey dey serious about stopping.
To block USSD betting, two approaches dey available. First, call your bank and ask them specifically to disable USSD transactions on your account — the agent fit do this as part of the same call where you request the MCC block. Second, most betting platforms that use USSD allow you to de-register your phone number from their shortcode service by sending a specific unsubscribe command (typically a menu option within the shortcode itself or an SMS to a deregistration number); check the betting platform’s help centre for the exact process. For the most durable protection, combine both: de-register at the platform level and request the USSD block at the bank level.
OPay, PalmPay and Moniepoint security settings to block online merchant payment
Mobile wallets account for roughly 25–30% of all betting deposits in Nigeria — OPay, PalmPay, and Moniepoint dey standard funding methods at Bet9ja, SportyBet, and BetKing. Since these wallets operate outside the traditional bank card and USSD infrastructure, a bank MCC block alone no go stop wallet-to-platform transfers. You must address each wallet separately.
OPay
Inside the OPay app, navigate to your card or account settings and locate the “Online Payment” or “Merchant Payment” toggle. Disabling this will block OPay-to-betting-site transactions. As an alternative or addition, you fit freeze your OPay card entirely under “Card Controls” — a frozen card declines all merchant charges until you unfreeze am. OPay’s in-app live chat dey available if you cannot locate the specific setting; ask them specifically to “disable online merchant payments” on your account.
PalmPay
PalmPay allows card freeze through “Card Settings” inside the app — a frozen card will decline all merchant charges, including betting top-ups. You fit also reduce your daily transaction limit under “Security” or “Card Controls” to create an additional friction layer. PalmPay’s in-app chat is the fastest support channel; if you escalate, request specifically that “online merchant payments to gambling categories” be blocked at the account level.
Moniepoint
Moniepoint card controls dey under “Card Management” or an equivalent section in the app. You fit disable online payments, reduce channel limits, or freeze the card from there. Moniepoint also provides customer support through in-app channels and an official call centre. For account-level restrictions beyond self-service, contact support and ask specifically for “online merchant payment” to be disabled on your account.
Extra layers wey go back up the bank block
The combination of a bank MCC block, saved-card removal, USSD disable, and wallet locks forms a strong, overlapping barrier — but the data on gambling harm recovery are clear: no single technical layer is sufficient on its own for someone wey dey dealing with compulsive betting. Defence in depth means stacking the layers so that even if one fails, the others hold the line.
- Operator-level self-exclusion: Every licensed Nigerian betting platform must provide a self-exclusion or account suspension option. Nigeria no get a national self-exclusion register as of May 2026, so you must request it at each platform individually — but doing so closes the account-access layer independent of payment infrastructure. Request a minimum of six months where the platform allows it.
- Device-level blocking software: Apps like Gamban and BetBlocker block gambling websites and apps at the device level, before any transaction even reaches the bank. Our blocking-software guide covers the options available to Nigerian users and how to set dem up on Android and iOS.
- Deposit, loss, and session time limits: Licensed platforms must offer these responsible gambling tools. Setting a ₦0 daily deposit limit — where the platform allows it — creates a hard stop independent of your payment methods entirely.
- Speak with someone: Gamble Alert (+234 916 295 7989 / gamblealert.org) na Nigeria’s dedicated gambling helpline. E dey free and confidential, staffed by people wey understand the local context — the economic pressure, the social environment, and what recovery actually looks like from inside Nigeria. You no need to be in crisis to call; early support dey consistently more effective than waiting until financial or personal damage becomes severe.
Frequently asked questions
Conclusion
The most effective way to block gambling transactions on your bank card in Nigeria na not a single action — na a stack of complementary layers, each one closing a gap the others can miss. A formal call to your bank to restrict MCC 7995 and 7993 dey serve as the foundation; removing saved cards from every betting platform closes the stored-credential bypass; disabling USSD shortcodes removes the fastest impulsive funding rail; and locking down OPay, PalmPay, and Moniepoint merchant payments covers the wallet layer that bank card infrastructure no reach. E no be one-tap like Monzo yet — but the evidence from people wey don use these combined measures say stacking the layers works.
