A Dutch KVK number and an Irish CRO number may appear on the same supplier’s paperwork. They do not necessarily identify two companies. An Irish-incorporated business with an establishment in the Netherlands can have a Dutch Business Register entry while its legal incorporation remains with Ireland’s Companies Registration Office (CRO). Before signing a contract, establish whether the Dutch operation is a branch, a separate Dutch BV or another business altogether.
Direct answer
Check the Irish legal company and CRO number at CRO CORE. Check the claimed Dutch establishment or Dutch company in the KVK Business Register. Match names, representatives, address and registration relationship, then make sure the contract and invoice identify the actual legal counterparty. A KVK entry does not automatically make a Dutch branch a separate company.
Why one business can have two register numbers
The Dutch Chamber of Commerce (KVK) assigns a KVK number to businesses and organisations in its Business Register. KVK says foreign companies with a Dutch establishment must register there, and it requests proof of registration from the country where the company was founded. An Irish company can therefore have an Irish incorporation number plus a Dutch register number for its Dutch presence. The records answer related but different questions.
Do not conclude that every Irish company selling in the Netherlands must have a KVK entry. A foreign company without a permanent Dutch establishment may not need one for ordinary trading; KVK identifies special cases, including paid provision of workers, that require separate attention. The question is fact-specific, so a missing KVK number is not by itself proof of fraud.
Branch, BV or trading partner?
| Structure | What to check | Who usually contracts? |
|---|---|---|
| Irish company with Dutch establishment | Irish CRO company plus linked Dutch KVK registration | The Irish legal company, acting through its establishment |
| Dutch BV owned by an Irish company | Dutch BV’s own KVK record and evidence of ownership | The Dutch BV if it signs the contract |
| Independent Dutch distributor | Distributor’s KVK record and distribution agreement if relevant | The distributor if it sells in its own name |
| Irish company selling remotely | Irish CRO record and actual sales terms | The Irish company, unless paperwork says otherwise |
A branch is not usually a separate legal entity; a Dutch BV is. An Irish parent’s impressive history does not automatically make it liable for a BV’s invoice or warranty, and a Dutch branch’s local address does not change the home company’s incorporation. Read our branch versus subsidiary guide when the structure affects credit, recourse or guarantees.
How to check the two records together
- Ask for the full Irish legal name and CRO number, plus the Dutch KVK number if an establishment or BV is claimed.
- Search the Irish company and compare status, directors, registered office and filing dates.
- Open CRO CORE for source confirmation when the transaction is material.
- Search the KVK number and inspect whether the Dutch entry is a foreign company’s establishment or a Dutch legal entity.
- Compare authorised representatives with the proposed signatory.
- Make sure purchase order, contract, invoice and bank payee name the same entity or explain each relationship.
- Save the register results and the date you checked them.
KVK says a basic search is public, while more detailed products such as a Business Register Extract or financial statements can cost money. An extract can provide a dated snapshot when a counterparty’s identity or representation is important. But an extract is not a guarantee that a website, email or payment instruction is genuine; verify contact channels independently.
Check representation and signing authority
The Dutch register contains information about officials and authorised representatives. Compare the proposed signatory’s name and role with the KVK entry, while recognising that authority may also depend on up-to-date internal delegations. The Irish company’s director list is useful context but does not automatically prove that every salesperson or branch manager can execute a particular contract. Ask for a power of attorney or board approval where the commitment is large.
Do not treat a person who shares a surname or address with a director as authorised. For high-value agreements, seek legal advice on signature form, governing law and enforceability. The KVK explanation of public register data lists what can be seen, but it does not replace reviewing the contract itself.
What Irish filings add to a Dutch check
The KVK record cannot substitute for the Irish home-company filing history. Check available CRO annual returns, financial statements and recent officer or address changes for the legal company that bears obligations. Confirm the reporting entity: group accounts, an Irish parent and a Dutch BV can present different financial pictures. Avoid attributing an Irish parent’s turnover to its Dutch establishment or assuming a subsidiary can call on every parent asset.
If the Irish company is young or files reduced accounts, public figures may be limited. Ask for current management information, references or security where the credit exposure warrants it. Our small-company accounts guide explains why a blank revenue line is not evidence of zero sales.
VAT, bank details and cross-border invoices
A KVK number, Irish CRO number and VAT number serve different purposes. The European Commission’s VIES service can validate a supplied EU VAT number for cross-border use, but it does not determine who signs the contract or whether the invoice is correctly taxed. Confirm the seller and VAT treatment for the actual supply with advisers if material.
Payment diversion is a separate risk. If a Dutch contact asks you to pay an Irish invoice to a newly supplied account, confirm the change through an independently sourced phone number and reconcile the beneficiary with the contracting entity. An attacker can copy both Irish and Dutch registration details from public records.
When a result does not match
Pause when the KVK number belongs to a different BV, the Irish CRO number refers to a dissolved company, the contract names a brand only, or the claimed branch cannot be linked to the Irish legal company. Ask the supplier to provide a current extract and written entity map. A mismatch may reflect a group restructuring or administrative delay, but the counterparty should be able to document it before you make an advance payment.
The EU’s BRIS-connected company search is another way to locate national-register records. It is a discovery route, not a replacement for matching the actual legal names and numbers. See also our legal versus trading name guide when branding obscures the entity.
