The Ksa published bank account checks guidance on October 8 after investigating nine online gambling operators using data from four Dutch banks. It found that minors could link their bank accounts to adult gambling accounts. The document applies across the licensed Dutch online market, beyond the nine operators in the study.

The sample and the market are different
That scope is worth separating from the sample. Nine operators were in the investigation, while the Ksa says its findings prompted clarification for the entire online market. An operator outside the study still has a verification process to review.
The announcement describes verification of bank accounts and other payment methods, including first names and business accounts. It does not identify a company receiving a fine. Readers should distinguish the guidance from a penalty decision against a named operator.
Bank account checks need more than initials
The guidance requires all full first names and the surname to match the player’s identity document. Initials alone are insufficient. The following distinction is useful when judging how an operator handles a name comparison:
- Full match: the account or payment can be accepted.
- Mismatch: the account or payment cannot be accepted.
- Partial match: additional checks are required before acceptance.
Take two relatives with the same surname and first initial. A shortened transaction name could fit either of them. This is our illustration of the problem, not a case reported by the Ksa. The extra names give the operator information the shortened record cannot supply.
Existing records are included
The guidance’s Q&A says operators must recheck accounts that missed the prescribed full-name verification. They can do this in bulk or at a later login, deposit or withdrawal. An account already checked correctly does not need a repeat review on this ground.
For a customer, that can explain a request arriving long after sign-up. The age of an account does not establish the completeness of its records. Keeping the same bank account for years also cannot supply a first name missing from the original check.
For operators, the question is how to find those records. A redesigned registration form helps the next customer, while a review of existing accounts addresses information already missing. The two tasks deal with different parts of the customer base.
Many operators already have a checking tool
The guidance says variants of a bank-data checking mechanism are already in use at two-thirds of Dutch online gambling operators. It stresses that the mechanism must be used correctly. That figure describes use of a tool, not the share of accounts that passed adequate checks.
This points to an implementation question as well as a technology question. Buying a checking service does not supply information missing from an old player record. We would look for which records need another review and how staff resolve partial matches.
Our report on Dutch online gambling licence renewals covered the supervision that continues after renewal. This guidance illustrates the ongoing work at customer-record level. Holding a current permit and verifying a particular payment are separate questions.
The story to follow is how operators carry out these bank account checks for existing customers as well as new sign-ups. Counting extra registration screens would tell us less than knowing which missing information the operator has actually addressed.
