How to Block Gambling Transactions on Your Bank Account

Turn it on tonight, in the app you already have

If your bank offers a gambling block, it’s usually a single toggle inside your banking app — under “card controls,” “security,” or “manage my card” — and it takes under two minutes to switch on. It works by declining any card transaction coded to a gambling merchant, whether that’s a sportsbook, an online casino, or a physical betting shop. You don’t need a new account, a new card, or anyone’s permission. You need the app you’re already carrying.

That’s the good news. The less good news, if you’re in the US, is that this feature is far more common at UK banks than American ones, and it has real gaps everywhere — crypto on-ramps, miscoded sites, cash withdrawals — that no toggle closes on its own. This guide walks through exactly how the block works, which banks actually have it, what to do if yours doesn’t, and how to layer it with the other tools that catch what a bank block misses. If you want the full plan beyond just the bank piece, our complete guide to quitting gambling covers the rest of it.

If you’re reading this mid-urge, do the toggle first, then come back and read the rest. If it’s worse than an urge — if you’re in crisis — the National Problem Gambling Helpline is free, confidential, and open right now: call or text 1-800-GAMBLER (routes through the Council on Compulsive Gambling of NJ) or 1-800-MY-RESET, the national helpline number as of 2026. Both are free. Neither requires an account or a diagnosis. See /help for the full directory.

How a bank gambling block actually works

Every card transaction carries a merchant category code (MCC) — a four-digit number the merchant’s payment processor assigns based on what kind of business it is. Gambling operators are typically coded 7995: betting, lottery tickets, casino gaming chips, off-track betting, and race-track wagers (Rapyd, MCC 7995).

When you switch on a gambling block, your bank’s system checks every incoming transaction against that code. If it matches 7995 (or the handful of adjacent gambling codes some processors use), the charge is declined at the point of sale — you’ll see it fail in real time, the same way a declined card fails at checkout. Nothing shows up on your statement because nothing goes through.

That’s the whole mechanism: a code check, not a judgment call. Which is exactly why it has predictable blind spots.

Where it slips through

• E-wallets and crypto exchanges. If you fund a crypto casino by first buying crypto on Coinbase or Kraken, your bank sees a purchase of cryptocurrency, not a gambling transaction. The MCC never fires.
• Miscoded or new merchants. Offshore sportsbooks and newer platforms don’t always register under 7995 with their processor — sometimes deliberately, sometimes just because their merchant account is still catching up. A site can be functionally a casino and still slide past the check under a “retail” or “digital goods” code.
• Cash. ATM withdrawals inside a casino, and cash advances at the cashier cage, often aren’t coded as gambling at all — they’re coded as cash access. The block doesn’t see them.
• Peer transfers. Venmo, Zelle, or a friend “spotting” you cash to bet with obviously bypass any merchant code entirely.

None of this means the block is pointless — it stops the single most common relapse path, which is opening the sportsbook app and tapping “deposit” on the card already in your wallet. It means the block is one layer, and you should treat it that way.

UK banks: the strong end of the spectrum

UK banks lead here, largely because Monzo built the first version in 2018 after customer demand, and the rest of the market followed under regulatory and public pressure. Over 700,000 Monzo customers have used their block, and more than three-quarters chose a cooldown longer than 24 hours (Monzo).

Every one of these blocks can be applied online, in-app, over the phone, or in branch, and none of them charge for it (GamCare). The UK Gambling Commission maintains its own explainer on setting these up if your specific bank isn’t listed above (Gambling Commission).

Why the delay is the entire point

Every UK bank on that list makes turning the block on instant and turning it off slow. That’s not a UX oversight — it’s the feature. Researchers at the University of Bristol’s Personal Finance Research Centre found that this kind of “positive friction” is central to why the blocks work: it removes the option to gamble in the ten seconds after an urge hits, which is the window where most relapse decisions actually get made (cited via GamCare).

If you’re setting this up tonight, don’t fight the delay — that’s the version of you at 11pm with a losing streak and a login screen open, and the delay exists specifically to outlast that version of you.

US banks: patchy, and here’s what to do about it

If you bank with Chase, Bank of America, Wells Fargo, or Capital One, don’t expect a dedicated gambling toggle the way you’d find at Monzo or Starling. As of 2026, gambling-block features have yet to gain real traction at US banks, while the large majority of UK banks offer one for free — a gap industry press and researchers have flagged repeatedly. Some US banks will apply gambling declines manually if you call and ask, but it isn’t a self-service app feature at most of them.

That’s not a dead end. It means you assemble the block yourself, out of tools that do exist:

• Call and ask directly. Some banks can flag your account or card for manual gambling-merchant declines even without a public toggle — it costs you a phone call, not a feature request. Ask specifically for MCC 7995 to be blocked or flagged, and get the change confirmed in writing (email or secure message) so it’s on record.
• Open a second, gambling-free account. Keep your direct deposit landing in a primary account with no card attached to any sportsbook or casino app, and move a fixed, spendable amount to a secondary account or prepaid card each week. The friction of a manual transfer does a version of what the UK cooldown does.
• Remove your card from every sportsbook and casino wallet. DraftKings, FanDuel, BetMGM, and every crypto casino store your card on file. Deleting it doesn’t stop you from re-adding it in thirty seconds, but it removes the one-tap deposit — the same friction principle, applied manually.
• Freeze your card at night. Most US banks’ apps do support a basic card lock/freeze, even without gambling-specific coding — Capital One’s is a straightforward toggle (Capital One). Freezing every card at a fixed hour (say, 9pm) blocks new deposits during your highest-risk window without needing your bank to build anything gambling-specific.
• Run cash-envelope periods for discretionary spending. If your card isn’t the risk — your phone’s saved payment method is — pulling a week’s spending money in cash and leaving the card at home removes the tap-to-pay path entirely.
• Set balance and transaction alerts. Every major US bank supports real-time push alerts for card transactions over a threshold you set. It won’t block anything, but it turns every attempted deposit into an immediate notification, which matters if a partner or accountability contact is watching the same alerts.

None of these are as clean as a UK-style toggle. Stack two or three of them and you get most of the way there.

Layer the block — don’t rely on it alone

A bank block, on its own, stops one thing: a card-present gambling transaction that’s correctly coded. It does not stop crypto funding, cash, miscoded sites, or you simply opening a new account somewhere your bank has no visibility into. GamCare’s own guidance is explicit that bank blocks work best “combined with self-exclusion and blocking software” (GamCare) — not as a standalone fix.

The three layers that actually cover each other’s gaps:

1. Bank block — stops the card-present deposit, the fastest and most common relapse path.
2. Self-exclusion — GamStop in the UK, or state-level self-exclusion programs in the US, legally bar you from licensed operators even if you find a new site with a card the bank block hasn’t flagged yet. Our self-exclusion guide walks through setup state by state.
3. Device/app blocking — stops you from even loading the sportsbook or casino site or app in the first place, closing the gap where crypto and offshore sites slip past a merchant code entirely. See our breakdown of gambling blocker apps if you don’t already have one running.

Each layer covers what the others miss. A bank block without device blocking still lets you browse and lose time to an offshore site funded in crypto. Device blocking without a bank block still lets you tap “deposit” the second you switch networks or devices. Run them together.

Cashout is building this as one guided setup rather than three separate tabs — per-bank gambling-block instructions alongside self-exclusion walkthroughs and app/site blocking, plus the panic-button and money-saved tracking that keep you in it once the urge has passed. It’s not out yet; we’re taking signups for early access on the waitlist while we finish iOS testing.

Shared accounts and partners

If you share an account with a partner, spouse, or family member, a gambling block affects every card tied to that account — which is usually the point, not a complication. Talk to whoever shares the account before you flip it on if you can; a block that appears out of nowhere on a joint card reads as suspicious or controlling even when the intent is the opposite.

If you’re the partner of someone gambling and you share finances, you have standing to request a block on a joint account through most UK banks, and to move your own income into a separate account they can’t access if the relationship needs that boundary right now. Our guide on gambling debt first steps covers untangling joint finances if debt is already part of the picture.

Do-it-tonight checklist

• Open your banking app and check under “card controls,” “security,” or “manage my card” for a gambling block.
• If it exists: turn it on now, and pick the longest cooldown option offered, not the shortest.
• If it doesn’t exist (most US banks): call your bank and ask them to flag your card for MCC 7995 declines; get confirmation in writing.
• Remove your saved card from every sportsbook, casino, and crypto exchange app on your phone.
• Set a real-time transaction alert for any charge over $20.
• Start (or finish) self-exclusion — see the self-exclusion guide.
• Install a device-level blocker so offshore and crypto sites can’t just be typed into a browser — see gambling blocker apps.
• Run the numbers on what you’ve actually lost with the gambling cost calculator — it’s a useful gut-check for the cooldown period, when the “just this once” argument gets loud.
• Save the crisis line to your phone: 1-800-GAMBLER or 1-800-MY-RESET, free, 24/7, no account needed — /help has the full list.

None of these steps requires waiting for anything to launch. Every one of them is something your bank, your phone, or a free helpline can do for you tonight.
