Just a few years ago, the journey of a new player looked relatively simple: an ad click, registration, choosing a payment method, and the first deposit. The fewer fields and screens stood between the user and the game, the higher conversion was. So operators trimmed forms, streamlined navigation, and tried to land an FTD as fast as possible.

In regulated markets, that logic no longer works on its own. Between the click and the first deposit, age and identity checks have appeared, along with data matching against government or commercial databases, geolocation, biometrics, payment instrument verification, and financial risk assessment. In some cases, the operator also has to request proof of address, source of funds, or source of wealth.

Every check solves a real problem. It helps keep minors out, flag fraud, stop multi-accounting, meet AML requirements, and protect the license. But at the same time, each additional step creates a fresh point where a legitimate player can drop out of registration.

As a result, compliance starts to directly shape acquisition economics. The operator buys traffic, the affiliate brings in a user, the payment service is ready to process the transaction, yet the player never makes it to the deposit. The reason may not be a lack of interest in the product, but an overly long form, an unrecognized document, a failed biometric check, or a request whose purpose nobody bothered to explain.

The core problem is that the paid click has already happened, yet the player has not materialized for the business.

Together with 3S.INFO, we break down where and why casinos lose users between the ad click, KYC, and the first deposit, how those losses drive up acquisition costs and cut affiliate revenue. Which metrics help pinpoint the problem stages, and how can verification be made smoother without weakening mandatory controls?

What Is the Problem for iGaming Markets?

KYC, Know Your Customer, is often seen as a single standard procedure: the user enters their details, uploads a document, and gets a verified account. In reality, it is a whole set of checks whose depth and sequence depend on the jurisdiction, the product, the payment method, the player's behavior, and the risk assessment attached to them.

  • What Is KYC? It is a mandatory identity verification and customer due diligence procedure carried out by financial institutions, banks, casinos, bookmakers, crypto exchanges, and other regulated companies.

No single form can work equally well across the UK, Malta, Ontario, Italy, and Brazil. Even if every country requires the operator to establish the customer's identity, the practical implementation of that requirement will differ.

In some places, most users can be verified automatically against databases. In others, their location has to be confirmed. In one market, a local identifier allows a person's details to be cross-checked quickly, while in another a foreigner has to upload several documents. In one case, enhanced due diligence kicks in only once a certain  risk appears; in another, the biometric step is baked into account creation from the start.

The timing of the checks also varies. Some data has to be verified before the player is allowed to play, while other details are confirmed once a financial threshold is reached or suspicious activity surfaces. That is why you cannot simply add a "Complete KYC" button to a global product and call localization done.

KYC Specifics Across Different GEOs

In iGaming, KYC is not a one-size-fits-all scenario that can be lifted from one GEO and dropped into another without changes. Identity verification requirements, the document set, and the order of checks depend on local regulation, while user habits shape how smooth the process feels. Let us break down which regional nuances are worth factoring in to combine compliance with a clear user experience.

United Kingdom: Verification Must Happen Before Play

In the UK, a remote operator must establish a customer's identity before that person is able to play. The minimum data to be verified includes name, address, and date of birth. Age must also be confirmed before a deposit is made, a bonus is used, or access to play is granted. This follows directly from the Gambling Commission's licensing conditions.

At the same time, verification does not necessarily mean every user has to upload a passport. Operators can cross-check details against credit agencies, the electoral register, and other available sources. Documents are requested only when an automatic match falls short. The regulator itself lists a passport, a driving license, and utility bills as possible, but not universally mandatory, forms of proof.

For conversion, the difference is fundamental. A player whose details the system confirmed in a few seconds, with no extra steps, barely notices KYC. A user whose data could not be matched automatically suddenly faces a completely different path: find a document, take a photo, wait for recognition, and sometimes re-upload it.

After that, financial risk checks and additional AML requests may kick in. Still, it would be wrong to claim that proof of source of funds is mandatory for every British player. Such measures depend on the circumstances, the volume of transactions, and the risks identified.

So for the operator, there is not one British funnel, but several. Most customers can sail through automatic verification almost unnoticed, while a smaller group gets routed down a far longer path. It is within that group that losses tend to be especially steep.

  • The UK iGaming overview paints a broad picture of the market: strict rules, a transparent licensing structure, high demands on operators, and a long history of online gambling. For affiliates, the UK is not the easiest GEO, but it is a highly instructive one: once you understand how regulation, licensing, and economics work here, it becomes far easier to assess the risks and prospects of iGaming markets in other countries.

Malta: A Risk-Based Approach Does Not Mean Identical Checks for Everyone

A Maltese licence also requires customer identification, AML controls, and ongoing monitoring of a client's transactions. But having obligations in place does not mean every player has to clear the same number of steps or supply the same set of documents.

The operator's job is to assess risk. Risk can be shaped by the country of residence, the payment instrument, the size and frequency of transactions, discrepancies in the data, unusual behavior, and other red flags. When risk rises, a routine check can escalate into enhanced due diligence, with extra documents, clarification of source of funds, or scrutiny of source of wealth.

This sets up a tricky challenge for the product. If you build registration around the strictest scenario, every customer ends up doing the extra work, including low-risk users. Conversion drops before the operator even gets a chance to assess the player's value.

If you make the path too easy, checks have to be pushed to a later stage. Then a player can register and even deposit, only to run into an unexpected request when their activity picks up or they try to withdraw. Formally, the operator is still meeting the requirements, but from the customer's perspective, it looks as though the casino took their money first and then threw up a roadblock before payout.

That is why a risk-based model only works when it is baked into the product. A compliance system has to do more than flag risk. It has to select a proportionate set of actions rather than sending every user through the toughest possible check.

Ontario: Identity Comes With a Location Check

In Ontario's regulated system, the operator needs more than just knowing who is trying to play. It also has to confirm that the user is actually located within the province. The geolocation requirement was baked into the local online gambling model from the start.

That creates yet another exit point, one that has nothing to do with the quality of the documents. A player may be of legal age, hold a valid payment instrument, and enter every detail correctly, yet still fail the location check. The culprit is often disabled device permissions, network quirks, a VPN, an outdated app, or an error in pinpointing coordinates.

From the user's standpoint, the difference between KYC, geolocation, and payment verification is irrelevant. All they see is that the casino won't let them continue. From the operator's standpoint, these are three separate systems, potentially owned by different teams and vendors.

Regulatory standards in Ontario are set by the Alcohol and Gaming Commission of Ontario, and compliance applies to registered operators and suppliers alike.

For an international brand, translating the registration form alone is not enough. You have to account for the availability of local data sources, identification rules, technical geolocation, and the behavior of Canadian payment methods. Otherwise, a user may sail through one check only to get lost at the next.

  • Ontario has remained one of the key talking points in the global iGaming community for several years now. The province did not just launch a regulated market; it effectively changed player behavior, steering them toward licensed operators. How did Ontario pull this off, what makes its model so appealing to regulators, brands, and affiliates from other countries, and what lessons from the Ontario experience are worth applying when building or reforming gambling regulation elsewhere?

Italy: The Gaming Account Is Tied to Local Infrastructure

In Italy, registration revolves around a named gaming account, the player's data, and the operator's system interacting with ADM infrastructure. New technical rules cover the transfer of identification data to a centralized system, confirmation of account creation, and configuration of credentials and limits. Only one gaming account per player is allowed with a given concessionaire, and payment instruments must be traceable and belong to the account holder. 

The codice fiscale, Italy's tax code, carries major weight, as it is used to uniquely identify an individual. For a local user, it is a familiar part of dealing with government and financial services. But for an international operator, it turns into a separate requirement around data, integrations, and verification.

The Italian example neatly shows why localization is not just about the language of the interface. A form can be flawlessly translated yet still ignore the format of the local identifier, the account opening sequence, central verification, payment restrictions, or the rules for setting gaming limits.

The more such requirements get layered onto a global product, the higher the risk of ending up with a path that technically complies with the rules but feels clunky to use. The user enters the same details several times, jumps between screens, and cannot grasp why the information they have already provided is not enough.

  • Italy's gambling market ranks among the most dynamic and high-performing in the world. Online casinos and bookmaker games are available here in every format, and the local audience uses them actively. This overview covers the key aspects of iGaming in Italy: current legislation and rules, approaches to working with the target audience and drawing it to websites, and the methods for running traffic to online betting and gambling.

Brazil: Biometrics Becomes Part of Registration

Brazil's regulated market is especially telling, because local identification and biometrics are built directly into the architecture of a player's account.

The operator has to link the account to a CPF, the individual taxpayer number, verify the user's data, and use facial recognition with liveness detection. Regulation also restricts the use of third-party payment instruments: the flow of money has to be tied to the account holder. Brazilian guidance on authentication data lists facial recognition with liveness checks and a password.

From an anti-fraud standpoint, the logic is clear. CPF and biometrics make it harder to spin up account networks, use someone else's data, and run automated bonus fraud. But for conversion, this means registration depends on more than the user's willingness to make a deposit.

Camera quality, lighting, internet connection, device quirks, and recognition accuracy all turn into commercial factors. Even a small share of technical failures on a large market translates into thousands of paid users who never reach their first deposit.

A Brazilian operator cannot simply strip out the biometric step to lift conversion. It can only make it clearer, faster, and more reliable. Here, compliance stops being a form that the legal team tacks on before launch. It becomes part of the core product.

  • Brazil iGaming Market News: On September 25, 2026, Brazilian President Luiz Inácio Lula da Silva announced a ban on online bookmakers and licensed betting companies. What does this decision mean for players, operators, affiliates, and the sports industry — from the headaches of refunds and lost investments to the threat of a sharp rise in illegal gambling?

The Verification Journey: Where Exactly Does a Casino Lose a Player?

The phrase "the user failed KYC" hides far too many different situations. A regulated funnel includes at least the following stages:

  1. the jump from an ad to the site;
  2. the start of registration;
  3. entry of personal data;
  4. phone or email confirmation;
  5. automatic identity matching;
  6. document upload if automated checks are not enough;
  7. biometric verification if required;
  8. location confirmation;
  9. adding a payment instrument;
  10. approval of the first transaction;
  11. first deposit.

A player can drop off at any of these steps. And the reasons vary just as much. On one screen, they don't want to enter too much data. On another, they can't tell which document will do. Then the camera fails to recognize the photo, the address is written in an unfamiliar format, and the bank declines the transaction.

Lumping all these cases into a single drop-off metric is a mistake. If an operator only sees the number of registrations started and the count of FTDs, they know the size of the loss but not where it comes from.

What's more, the causes can differ by channel. Mobile users run into camera and geolocation permissions more often. Foreigners hit the absence of a local document. Customers of certain banks deal with payment declines. The audience from a specific affiliate may arrive on devices or from regions where the chosen identity provider performs worse.

Without that granularity, an operator risks writing off a traffic source as low quality when the real problem sits inside their own registration.

The Affiliate Pays for a Process It Doesn't Control

The tension is especially sharp in affiliate marketing. The affiliate owns the ad, the page content, the audience targeting, and the cost per click. Once the user lands on the operator's site, control all but evaporates.

From there, the outcome hinges on site speed, the registration form, the KYC provider, payment methods, geolocation, and the casino's internal rules. But under the CPA model, the affiliate only gets paid after the target action is completed — usually registration and a qualified first deposit.

It is a strange arrangement. One side attracts and pays for the user, while the other controls most of the journey to the paid conversion. If a document is not recognized or a deposit is declined, the costs stay with the partner.

In a revenue share model, the problem takes a different shape but doesn't go away. A user who flunks verification never turns into an active player and never generates future revenue. The affiliate loses out on potential LTV, despite having already plowed money into content, SEO, or paid media.

The most dangerous situations arise when an operator changes its KYC process without telling partners. For instance, it adds a mandatory document, switches to a different provider, or tightens payment checks. Traffic quality stays the same on paper, but FTD conversion falls off a cliff. The partner sees the stats deteriorate but cannot pin down the cause.

That is why transparency around the regulated funnel is becoming part of the partner offering. Operators will have to compete not only on CPA size and RevShare percentages, but also on their ability to turn legitimate traffic into verified players efficiently.

FTD Is No Longer Enough

The first deposit remains an important commercial metric, but it does not explain how the user got there. Two operators can land the same number of registrations yet show completely different verification efficiency.

To manage the process, you need to measure:

  • the share of users who complete the registration form;
  • the percentage of automatic identity confirmations;
  • the share of customers routed to document upload;
  • the number of successful checks on the first attempt;
  • the frequency of re-uploads;
  • the average confirmation time;
  • the share of manual reviews;
  • conversion from completed KYC to deposit;
  • the percentage of approved payments;
  • losses on geolocation and biometrics;
  • results by device, market, bank, and traffic source.

Instead of a single FTD cost, it pays to calculate the cost of acquiring a verified player with a successful deposit. That metric captures the real outcome of the entire chain: marketing, product, KYC, and payments.

If an affiliate brings in 1,000 users at €10 each, the traffic costs €10,000. With a 30% registration conversion, the operator ends up with 300 accounts. If 70% of those get their identity confirmed, 210 users remain. If 60% of the verified users make a successful deposit, the operator lands 126 players.

The formal cost per registration works out to around €33. But the cost of a real, verified depositor comes closer to €79. If KYC conversion drops from 70% to 50%, that figure climbs to roughly €111, even if the cost per click, the ad campaign, and the audience's intent have not changed at all.

That is how compliance shifts from an abstract requirement into a variable in unit economics.

Why You Can't Just Defer Verification Until Withdrawal

The most obvious solution is to make the entry as easy as possible and request documents later. Initial conversion may indeed go up. But the problem does not disappear; it just shifts to a far more sensitive point.

When a casino demands extra documents only at withdrawal, the player reads it as an artificial delay on their payout. Support tickets pile up, complaints hit the forums, and accusations of bad faith start flying. Even a legitimate request sparks conflict if the operator never flagged it as a possibility earlier.

What's more, mandatory checks cannot simply be pushed to a later stage at will. The UK regulator, for instance, explicitly states that an operator should not demand proof of age and identity for the first time at withdrawal if it could have asked earlier. Additional information for AML purposes can be requested, but it has to be gathered in a timely manner, not deployed as a surprise obstacle to a payout. 

Strong registration does not hide compliance. It spells out upfront what data will be needed, explains why the check is happening, and does not make the user repeat steps they have already completed.

Maximum Checks Don’t Mean Maximum Security

Tough KYC is often seen as more reliable. But piling on more documents does not guarantee quality control.

A professional fraudster prepares for the check in advance, leaning on purchased data, synthetic identities, forged documents, or biometric spoofing tools. An ordinary user, by contrast, may bail after the first confusing request. The upshot: a poorly tuned system throws up more hurdles for legitimate users than for organized fraud.

An effective model has to tell low risk from high risk. A user whose details are instantly confirmed against reliable sources and whose behavior raises no flags should not walk the same path as an account with document discrepancies, a suspicious device, and unusual transactions.

Therefore, operators don't need the heaviest KYC — they need the most precise. Minimum sufficient checks for an everyday customer, plus timely escalation of controls the moment risk appears.

Compliance Becomes a Product Function

The regulated funnel has no single owner. The compliance team defines the requirements. The product team turns them into screens and flows. The KYC provider verifies data. The payment system approves or declines the transaction. Marketing and affiliates bring in the user. Support cleans up the fallout from mistakes.

If every participant optimizes only their own metric, the whole system falls apart. Compliance reduces risk but never sees the conversion losses. Marketing drives registrations but has no clue what happens with documents. The payments team tracks transaction approvals but never ties them back to the traffic source. The affiliate watches FTD drop and concludes the offer has stopped working.

The process can only be pulled together around one shared metric: how many acquired users turned into verified players with a successful deposit, and what that cost the business.

That means operators need local scenarios, not one global form. Data should be confirmed automatically wherever possible, registration progress should be saved, requests should come with an explanation, photo requirements should be clear, and an alternative verification route should be offered when something breaks technically.

A KYC provider should also be judged on more than the price of a single check. A cheap solution can turn out expensive if it keeps sending people to manual review or handles local documents poorly. What matters is the share of checks passed on the first attempt, response time, the number of false rejections, and the final conversion to deposit.

The same goes for affiliate analytics. A partner does not have to see sensitive player data, but they can be shown anonymized stage-by-stage stats: how many users started registration, how many cleared automatic verification, how many hit a document request, and how many made it to payment. Then the conversation about traffic quality rests on facts instead of mutual suspicion.

It Won't Be the ‘Easiest’ Casino That Wins

An operator has no real choice between compliance and conversion. Skipping mandatory checks can lift short-term revenue, but it also creates exposure to fines, fraud, and losing the license. Overbearing controls protect on paper, yet they make acquisition too expensive and hand part of the audience to competitors or the illegal market.

Competitive advantage lives between those two extremes.

The winners will be operators who can verify most ordinary customers invisibly, flag elevated risk in good time, and avoid dragging the entire audience through one maximally complex scenario. For them, compliance becomes not a barrier after the ad, but part of the product — as measurable and optimizable as the payment page, the bonus, or the casino lobby.

In regulated iGaming, buying quality traffic is not enough. You also have to keep hold of it between the click, KYC, and the first deposit. And if an operator and its affiliate only see the start and the end of that journey, they miss the crucial part: who is paying for everything in between, where, and why.
