How to Block Gambling Transactions at Your Bank
A bank-level gambling block stops the payment before it ever reaches the casino — which makes it a stronger barrier than a casino’s own deposit limit, since it doesn’t depend on that individual operator honoring the setting. It’s also free, doesn’t close your account, and doesn’t affect your credit score.

How It Works
Banks identify gambling transactions using merchant category codes (MCCs) — a standardized code every card payment carries that identifies what kind of business the merchant is. When you switch on a gambling block, the bank declines any transaction tagged with a gambling MCC, without you having to identify or list individual casino names yourself.
UK Banks: Widely Available
Gambling blocks are now offered by roughly nine in ten UK banks, including all the major high-street names. The details vary slightly by bank:
| Bank | How to activate | Notes |
|---|---|---|
| Monzo | In-app toggle | Requires contacting customer service and a 48-hour wait to turn back off |
| Starling | In-app toggle | Self-service on and off |
| Barclays | App, under “Your Cards” | Must be repeated separately for each card on the account |
| HSBC | App or online banking | Once active, blocks for a minimum of 72 hours |
| NatWest / Lloyds | App or online banking | Offered as part of each bank’s standard app features |
A Gambling Harms Action Lab program — funded by a UK Gambling Commission regulatory settlement — has brought together Barclays, First Direct, HSBC UK, Monzo, Nationwide, Starling and Virgin Money to further improve these tools, so expect continued refinement across providers.
The cooling-off delay is the point, not a flaw. Both Monzo’s 48-hour wait and HSBC’s 72-hour minimum are deliberately designed so you can’t simply switch the block off in the moment you’re tempted to gamble.
US Banks: Less Standardized
The US doesn’t have the same near-universal availability of dedicated gambling blocks — coverage varies significantly by bank and by card issuer. Many banks are actively expanding these features, but there’s no single feature name or guaranteed toggle every US customer can rely on the way UK customers largely can. Check your specific bank’s app or call customer service to ask directly whether gambling-category blocking is available on your card.
Third-Party Blockers: Closing the Gaps a Bank Block Can’t
A bank block only stops that specific card. It won’t stop you paying by bank transfer, cash, cryptocurrency, or a different card entirely. This is where dedicated blocking software adds a second layer:
Gamban
A paid subscription (around $2.49/month or $24.99/year, free in some regions) that blocks thousands of gambling sites and apps across phone, tablet and desktop. Works at the device level, so it doesn't depend on merchant codes at all.
BetBlocker
A free tool from a registered charity, blocking tens of thousands of gambling sites across multiple platforms, with a scheduling feature that lets you lock in a restricted period you can't easily reverse early.
Neither tool can guarantee 100% coverage — new gambling sites launch constantly, and a determined user can find workarounds like cash or e-wallets. The realistic goal is friction, not an unbreakable lock: every extra step between an urge and a deposit reduces the chance of following through on it.
Putting the Layers Together
- Set a bank-level gambling block on every card you hold, not just your main one.
- Add a device-level blocker (Gamban or BetBlocker) to cover bank transfers, cash apps, and browsing gambling sites in the first place.
- Register for self-exclusion. In the UK, that’s GAMSTOP, covering every licensed operator at once. In the US, check your state regulator’s self-exclusion program.
- Tell someone. A partner, family member, or friend who knows can help you stick with the block during the exact moments you’d otherwise be tempted to remove it.

Frequently Asked Questions
- Will a bank gambling block affect my credit score?
- No. It simply declines transactions carrying a gambling merchant code — it doesn't close your account or appear on your credit file.
- Why do some banks make it hard to turn the block back off?
- The delay — 48 hours at Monzo, a minimum of 72 hours at HSBC — is intentional, to stop the block being removed impulsively in the moment of an urge to gamble.
- Does a bank block stop bank transfers to a casino, not just card payments?
- Not necessarily — coverage depends on the bank and payment method. A device-level blocker like Gamban or BetBlocker, or a full self-exclusion registration, closes more of these gaps.
