When you register a company in the Netherlands, you will quickly encounter two different identification numbers: a KvK number and a VAT number. They are issued by different authorities, serve different purposes, and are used in different situations. Knowing which is which helps prevent mistakes on invoices, contracts, and tax filings—and helps you stay compliant from day one.

What is a KvK number in the Netherlands?

A KvK number (Kamer van Koophandel number) is an eight-digit registration number assigned by the Dutch Chamber of Commerce when a company registers in the Netherlands. It is the official identifier for your legal entity in the Dutch commercial register, confirming that your company exists as a recognised business under Dutch law.

Every legal entity registered in the Netherlands receives a KvK number at the point of incorporation. For a BV (besloten vennootschap), this happens when the notarial deed is signed and the company is filed with the Chamber of Commerce. The number stays with the company for its entire existence and is publicly searchable in the Dutch trade register.

The KvK number is primarily an administrative and legal identifier. It appears on company letterheads, in contracts, on the Dutch Chamber of Commerce extract, and in any formal correspondence where your company’s legal identity needs to be confirmed. It does not relate directly to tax obligations—that is handled by a separate number.

What is a VAT number and how does it work in the Netherlands?

A Dutch VAT number (btw-nummer) is a tax identification number issued by the Dutch Tax and Customs Administration (Belastingdienst) for VAT purposes. It follows the format NL + nine digits + B + two digits. Companies use it to charge VAT on sales, reclaim VAT on costs, and file VAT returns with the Dutch tax authority.

VAT registration in the Netherlands is handled separately from KvK registration. Once a company is registered with the Chamber of Commerce, the Belastingdienst typically issues a VAT number automatically for BVs and other corporate entities. However, the timing and process can vary depending on the company’s structure and whether it is actively trading.

The Dutch VAT number is the number you include on invoices when charging VAT to customers. It also identifies your company in cross-border EU transactions. When supplying goods or services to VAT-registered businesses in other EU member states, your Dutch VAT number confirms your status as a taxable entity and enables the application of the zero rate or the reverse-charge mechanism, where applicable.

Foreign companies that are VAT-registered in the Netherlands but do not have a Dutch legal entity may also receive a VAT number through a fiscal representative. This is a separate situation from a company that has incorporated a Dutch BV and gone through standard VAT registration procedures in the Netherlands.

What is the difference between a KvK number and a VAT number?

The key difference is their purpose and the authority that issues them. A KvK number is a commercial registration number issued by the Chamber of Commerce—it identifies your legal entity. A VAT number is a tax identifier issued by the Belastingdienst—it identifies your company for VAT purposes. One confirms your existence as a business; the other governs your tax obligations.

Here is a practical comparison:

• KvK number: Eight digits, issued by the Dutch Chamber of Commerce, identifies the legal entity in the commercial register
• VAT number: Format NL + digits + B + digits, issued by the Belastingdienst, used for VAT filing, invoicing, and cross-border EU transactions
• KvK number purpose: Legal identity, contracts, official correspondence, public trade register
• VAT number purpose: Charging and reclaiming VAT, filing VAT returns, intra-EU trade

A useful way to think about it is this: the KvK number answers the question, “Does this company legally exist in the Netherlands?” The VAT number answers the question, “Is this company registered for tax purposes and authorised to handle VAT?” Both are needed for a fully operational Dutch entity, but they operate in completely different domains.

Does every Dutch company need both a KvK and a VAT number?

Most active Dutch companies need both. Any company incorporated in the Netherlands receives a KvK number automatically upon registration. Whether you also need a VAT number depends on your activities, but the vast majority of trading companies, holding structures, and operational entities will require one for VAT registration in the Netherlands.

There are some nuances worth understanding:

• Holding companies with no active operations: A pure holding company that only holds shares and receives dividends may not be required to register for VAT, as it may not be considered a VAT entrepreneur under Dutch law. This depends on the specific facts and structure.
• Finance vehicles and SPVs: These may or may not require VAT registration depending on their activities. Intercompany financing is generally VAT-exempt, which can affect both the registration requirement and the right to reclaim input VAT.
• Actively trading companies: Any company buying and selling goods or services in the Netherlands will need a VAT number to comply with Dutch VAT obligations.

For foreign companies establishing a Dutch entity, the default assumption should be that both numbers are needed. If there is any question about whether your specific structure requires VAT registration, it is worth clarifying with a Dutch tax adviser before you start operating.

Where do you use your KvK number vs. your VAT number?

Your KvK number is used in legal and administrative contexts. Your VAT number is used in financial and tax contexts. In practice, this means they appear in different places and serve different audiences—one confirms your corporate identity, the other your tax status.

Where to use your KvK number

• Company letterhead and official correspondence
• Contracts and agreements
• Opening a Dutch business bank account
• Applying for permits or licences
• Official filings with Dutch authorities
• Responses to due diligence requests

Where to use your VAT number

• Sales invoices issued to customers (required under Dutch invoicing rules)
• Intra-EU supplies of goods and services (reverse charge and zero-rate transactions)
• VAT returns filed with the Belastingdienst
• EU VAT Information Exchange System (VIES) checks by counterparties
• Reclaiming VAT on business costs

Both numbers are often included on invoices issued by Dutch companies. Dutch invoicing requirements specify that invoices must show the VAT number, and many companies also include the KvK number as standard practice. If you are issuing invoices from your Dutch BV, including both is the safest approach.

How do you find or verify a Dutch KvK or VAT number?

You can find and verify both numbers through publicly available Dutch government tools. The KvK number is searchable via the Dutch Chamber of Commerce trade register at kvk.nl. The VAT number can be verified through the EU’s VIES system (ec.europa.eu/taxation_customs/vies), which confirms whether a VAT number is valid and active across all EU member states.

For your own company’s numbers, the KvK number appears on the Chamber of Commerce extract (uittreksel) issued at the time of registration. Your VAT number is included in the correspondence from the Belastingdienst confirming your VAT registration. Both should be stored securely and made available to your finance and legal teams from day one.

If you are verifying a supplier’s or counterparty’s numbers, the VIES check is the standard tool for VAT numbers, particularly for intra-EU transactions. A valid VIES result confirms that the number is active and can be used for zero-rated transactions within the EU. For KvK verification, the public trade register at kvk.nl provides the official company extract, including registration status, directors, and registered address.

Understanding the difference between a KvK number and a VAT number is one of the first practical steps when setting up or operating in the Netherlands. Getting both right from the start avoids compliance issues down the line.
