Which banks does the company hold accounts with?

Bank accounts are part of the customer due diligence of the customer

This is usually a question from the customer due diligence that the customer of the company must perform under the Dutch Money Laundering and Terrorist Financing (Prevention) Act (Wwft). The customer — often a bank or a larger buyer that itself has a Wwft obligation — wants to know through which bank accounts payments flow, in order to verify that this is consistent with the rest of the picture: name, address, sector and the source of the money. The question often stands alone, but substantively belongs with questions about the source of the company's assets and about the identity of the company itself.

There is no fixed format for the answer. Some portals only ask for the country and the bank, others want to see an IBAN or a recent bank statement as proof. If the company has accounts at multiple banks, it is customary to list them all — unless the question specifically asks for the account used for this relationship. If proof is missing, the answer can often still be given on the basis of the company's own records; the system does not assume a "yes" here without a source in the supply chain file. Sensitive combinations, such as IBAN together with balances, can be shielded with the confidentiality button until the customer agrees.

Where this follows from the Wwft

The basis lies in the customer due diligence from the Wwft: the institution that accepts the company as a customer must conduct research into the business relationship and the money flows associated with it, and bank details are a customary part of that. The law itself does not prescribe which form the bank uses — that varies by institution — but the obligation to request and assess this type of information is set out in the Wwft.
