What does a Netherlands VAT number look like?

mei 28, 2026

A Netherlands VAT number follows a fixed format that every foreign company should recognise before starting operations in the country. Whether you are setting up a Dutch entity, invoicing Dutch clients, or managing cross-border VAT flows, knowing how the Dutch VAT system works in practice saves time and prevents compliance errors.

Here is a direct answer: a Dutch VAT number consists of the country code NL, followed by nine digits, the letter B, and two more digits. It looks like this: NL123456789B01. Every registered business receives one upon VAT registration with the Dutch Tax Authority (Belastingdienst). The sections below walk through everything you need to know about obtaining, using, and verifying a Dutch VAT number.

What is a Netherlands VAT number?

A Netherlands VAT number, known locally as a btw-nummer, is the unique identifier assigned to a business registered for VAT in the Netherlands. It is used on invoices, VAT returns, and all official correspondence with the Dutch Tax Authority. Without a valid btw-nummer, a business cannot legally charge or reclaim VAT in the Netherlands.

The btw-nummer serves as the primary reference point for all Dutch VAT obligations. When a foreign company establishes a Dutch entity or registers for VAT as a non-resident business, the Belastingdienst issues this number as part of the registration process. It appears on every VAT return filed, every invoice issued to a Dutch or EU customer, and every communication with the Dutch tax authorities.

For foreign companies operating in the Netherlands, VAT registration is not just a formality. It connects the business to the Dutch VAT reporting cycle, which typically requires quarterly or monthly filings depending on the scale of activity. Getting this right from the start matters, because late registration carries penalties and can complicate the recovery of input VAT already paid.

What does a Dutch VAT number look like?

A Dutch VAT number follows the format: NL + 9 digits + B + 2 digits. An example looks like this: NL123456789B01. The NL prefix identifies the country, the nine-digit sequence is linked to the legal entity, the letter B signals that it is a VAT identifier, and the two-digit suffix typically starts at 01 and increments if additional VAT numbers are issued to the same entity.

This format is standardised across the Netherlands and applies to all registered entities, whether a Dutch BV, a branch office, or a foreign company with a Dutch VAT registration. The total character count is always 14, which makes it straightforward to validate programmatically or by eye.

When issuing invoices to other EU businesses, the btw-nummer must appear on the invoice. EU customers use it to verify the supplier’s VAT status and to apply the reverse-charge mechanism where applicable. Formatting errors, such as omitting the B or using an incorrect digit count, can cause invoice rejections and create unnecessary friction in your counterparty’s accounts payable process.

What is the difference between a BTW number and a RSIN?

The BTW number and the RSIN are related but distinct identifiers. The RSIN (Rechtspersonen en Samenwerkingsverbanden Informatienummer) is a general legal-entity number assigned by the Dutch Chamber of Commerce (KvK). The BTW number is the VAT-specific identifier issued by the Belastingdienst. In many cases, the nine-digit core of the BTW number is identical to the RSIN, but they serve different purposes and are used in different contexts.

The RSIN appears in the KvK trade register and is used for corporate identification across Dutch government systems. The BTW number is used exclusively for VAT purposes, on invoices, VAT returns, and intra-EU transaction reporting. A company can have an RSIN without having a BTW number if it is not VAT-registered, but a company with a BTW number will always have an underlying RSIN.

For foreign companies, this distinction matters during setup. KvK registration produces the RSIN. Subsequent VAT registration with the Belastingdienst produces the BTW number. Both steps are separate, and both are necessary before the business can operate fully in compliance with Dutch law. Confusing the two can lead to incorrect numbers appearing on invoices, which creates problems during VAT audits.

Who needs a VAT number in the Netherlands?

Any business that supplies goods or services in the Netherlands that are subject to Dutch VAT is required to register for a VAT number. This applies to Dutch legal entities such as BVs, but also to foreign companies that have a fixed establishment in the Netherlands, import goods into the Netherlands, or make taxable supplies to Dutch customers without a local entity.

The scope is broader than many foreign companies initially expect. The following situations typically trigger a Dutch VAT registration obligation:

Operating a Dutch BV or branch with taxable commercial activity
Importing goods into the Netherlands for sale within the EU
Supplying goods stored in a Dutch warehouse to Dutch or EU customers
Providing certain services to Dutch businesses where the place of supply is the Netherlands
Acquiring goods from other EU member states above the relevant threshold

Foreign companies that only supply services to Dutch VAT-registered businesses may, in some cases, rely on the reverse-charge mechanism, shifting the VAT obligation to the customer. However, this does not eliminate the need to understand the rules, and in many structures, direct registration remains the cleaner and more defensible approach. If you are unsure whether your specific activity triggers a registration obligation, getting a clear answer early prevents retroactive compliance issues.

How do you apply for a Netherlands VAT number?

To apply for a Dutch VAT number, a business must submit a registration request to the Belastingdienst. For Dutch legal entities such as a BV, VAT registration typically follows automatically, or shortly after KvK registration. For foreign companies registering without a Dutch legal entity, the process involves submitting a specific form to the Belastingdienst office that handles non-resident registrations.

The general steps for VAT registration in the Netherlands are:

Register with the KvK if establishing a Dutch entity. This produces the RSIN and KvK number.
Submit a VAT registration request to the Belastingdienst, either as part of the KvK process or separately for non-resident registrations.
Provide supporting documentation, which typically includes details of the business activity, the entity’s legal structure, and evidence of the VAT obligation in the Netherlands.
Receive the BTW-nummer by post from the Belastingdienst, usually within a few weeks of submitting a complete application.

Processing times vary. Standard registrations for Dutch BVs tend to move quickly. Non-resident registrations can take longer, particularly if the Belastingdienst requests additional information about the nature of the business activity. For companies that need to start invoicing or importing before the number arrives, this timeline is worth factoring into the setup plan. Filing VAT returns without a confirmed number is not possible, and delays in registration can push back the date from which input VAT can be recovered.

How can you verify a Dutch VAT number?

A Dutch VAT number can be verified through the EU’s official VIES system (VAT Information Exchange System), available at ec.europa.eu/taxation_customs/vies. Enter the NL prefix and the number, and the system confirms whether the number is valid and active. This check is free, takes seconds, and is the standard method used across the EU for cross-border VAT verification.

Verifying VAT numbers matters for practical reasons. When applying the zero VAT rate on intra-EU supplies, the supplier must confirm that the customer holds a valid VAT number in their member state. If the number cannot be verified and the transaction is later audited, the zero rate may be challenged, and the supplier could face a VAT assessment. Running a VIES check before issuing the invoice and retaining a record of the result is standard practice for any business handling intra-EU transactions at volume.

For Dutch domestic transactions, the Belastingdienst also provides a verification option through its own portal. This can be useful when dealing with Dutch-only counterparties or when the VIES result is inconclusive. In practice, most finance teams rely on VIES as the primary tool, supplemented by the Belastingdienst portal where needed.

What mistakes should you avoid with Dutch VAT numbers?

The most common mistakes foreign companies make with Dutch VAT numbers fall into a few clear categories: using the wrong number format on invoices, confusing the RSIN with the BTW number, registering too late, and failing to keep VAT filings current after the number is issued. Each of these creates compliance exposure that is avoidable with the right setup.

Here are the errors worth watching for:

Putting the RSIN on invoices instead of the BTW number. These numbers may look similar but serve different purposes. Only the BTW number belongs on a VAT invoice.
Delaying registration. VAT obligations arise from the moment taxable activity begins, not from when the number is received. Retroactive registration can result in penalties and interest on late filings.
Failing to file nil returns. If a business is VAT-registered but has no activity in a period, a nil return is still required. Missing it triggers automatic penalties.
Not verifying customer VAT numbers before applying the zero rate. The zero rate on intra-EU supplies requires a valid, verifiable VAT number from the customer. Skipping this step creates audit risk.
Using an expired or deregistered number. If a counterparty’s VAT registration has lapsed, continuing to treat them as VAT-registered creates problems on both sides of the transaction.

For foreign companies managing Dutch VAT from a distance, these errors tend to surface during audits rather than in real time. Building the right verification and filing routines from the start is far less disruptive than correcting historical filings under pressure.

Getting Dutch VAT registration right is one of those areas where the details matter more than they appear at first. The format, the filing obligations, the verification requirements, and the interaction with other Dutch registration numbers all connect in ways that can create real compliance risk if handled loosely.
