How to verify VAT number in Belgium?

Belgium VAT validation on VIES website​

To verify a Belgian VAT number:

  2. Select Belgium (BE) from the member state dropdown.
  3. Enter the 10-digit VAT number (without the BE prefix), e.g. 0404621642.
  4. Submit — results appear immediately.

Frequently Asked Questions​

What is the structure of a Belgian VAT number, and is it the same as the enterprise number?​

A Belgian VAT number is BE + 10 digits (e.g. BE0404621642). The 10-digit portion is identical to the KBO/BCE enterprise number (Kruispuntbank van Ondernemingen). The first digit is 0 for companies registered before 2014 and 1 from 2014 onward. The last two digits are a check digit: check = 97 − (first 8 digits mod 97). The enterprise number is used for VAT, social security, company filings, and all government interactions. [1]

My Belgian supplier claims they are exempt from VAT — what is the small enterprise threshold?​

Belgium's small enterprise VAT exemption applies to businesses with annual turnover below €25,000. Exempt businesses do not charge VAT and do not have a VAT registration (though they have a KBO enterprise number). Their invoices must state "Vrijgesteld van BTW — artikel 56bis WBTW" or "Exonéré de TVA — article 56bis CTVA". From 2025, the EU harmonized scheme also allows cross-border exemptions for eligible businesses with EU-wide turnover under €100,000. [1]

VIES confirms whether a Belgian VAT number is active for intra-EU transactions and returns the company name and address. The CBE Public Search (kbopub.economie.fgov.be) provides more detail: entity type, NACE activity codes, authorized persons, establishment units, and company status (active/stopped). Use VIES for VAT validation; use CBE for due diligence. The MyMinfin portal allows bulk VAT certificate requests for processing large supplier lists. [1] [2]

What is a Belgian VAT group, and why would I see a VAT number starting with BE04?​

Belgian law allows related companies to form a VAT group (BTW-eenheid / unité TVA), which files a single consolidated VAT return. The VAT group number is assigned by SPF Finances and typically starts with BE04. Member companies retain their individual enterprise numbers but use the group VAT number for all external transactions. Verify BE04-prefix numbers on VIES as usual — they are valid. For identifying the specific contracting legal entity, request the company's individual KBO enterprise number. [1]

My company sells SaaS to Belgian businesses — do I need a Belgian VAT number?​

For B2B digital services, the reverse charge mechanism applies — the Belgian customer self-assesses VAT, and you do not need Belgian VAT registration. For B2C digital services, non-Belgian EU businesses with cross-border digital B2C sales above €10,000 EU-wide must register for EU OSS in their home country. Non-EU businesses use non-Union OSS or IOSS. Belgian VAT rates: 21% standard, 12% food service/housing, 6% food/books/medicines/hotels, 0% newspapers. [1]

What are the mandatory fields on a Belgian VAT invoice?​

A Belgian VAT invoice must contain: (1) Invoice date and unique sequential number; (2) Supplier's name, address, and BTW/TVA number; (3) Customer's name and address (and VAT number for B2B); (4) Description of goods/services, quantity, unit price; (5) Date of supply if different from invoice date; (6) VAT rate(s) and VAT amount per rate; (7) Total excluding and including VAT; (8) For reverse charge: "Autoliquidation — Verlegging van heffing". Invoices must be issued within 15 days of the end of the supply month. [1]

How do I verify a Belgian VAT number using MyMinfin, and when is it needed over VIES?​

MyMinfin (eservices.minfin.fgov.be) allows businesses to: (1) request an official VAT certificate (attestation de qualité d'assujetti) showing registration status and authorized activities — more authoritative than a VIES screenshot; (2) submit bulk validation requests for multiple VAT numbers via Excel upload. MyMinfin requires Belgian eID or CSAM login. Use it when a counterpart requires a certified certificate rather than a VIES printout, or when validating a large supplier list. [1]
