How is a Dutch VAT number structured?
A Dutch VAT identification number (BTW-id) follows a fixed format consisting of the country code "NL", followed by 9 digits, the letter "B" and a 2-digit sequence number.
- Country code:always "NL" for the Netherlands.
- 9 digits: the fiscal identification number.
- Letter B: separator between number and sequence number.
- Sequence number:2 digits (01-99), usually B01 for a company's first VAT number.
Example: NL123456789B01 — this is the first VAT ID of a fictional company.

What do developers use fictional VAT numbers for?
Developers use fictional VAT numbers for testing invoice systems, accounting software, ERP systems, VAT return applications and e-commerce platforms. Also for validating international input forms, API integrations with tax authorities and setting up test data for cross-border EU trade scenarios with multiple countries.
Can I generate multiple VAT numbers at once?
Yes, with the bulk generator you can generate up to 10,000 fictional VAT numbers at once for any of the 8 supported countries. All numbers are created client-side — no data is sent to a server. Export to Excel (.xlsx), CSV, or JSON for direct import into your test systems.
Does the generator store my generated VAT numbers?
No. The VAT number generator runs entirely in your browser. No data is stored or transmitted. After leaving the page, the numbers are gone, unless you exported them.
