About VAT Numbers
VAT (Value Added Tax) identification numbers are used by businesses in the EU and other countries for tax purposes. Each country has its own format, typically starting with a 2-letter country code followed by digits and sometimes letters. These generated numbers follow the correct format but are for testing purposes only.
What is This Tool?
A VAT number generator creates valid-format Value Added Tax identification numbers for testing tax compliance systems, invoicing software, and EU trade applications. Generated numbers follow country-specific VAT formats including correct prefixes, lengths, and check digit algorithms.
VAT identification numbers are required for intra-EU trade under the VAT Information Exchange System (VIES). Each EU member state has its own format — Germany uses DE followed by 9 digits, France uses FR with 2 check characters and 9 digits, and the UK (post-Brexit) uses GB formats. Correct VAT formatting is critical for invoice compliance.

Frequently Asked Questions
Are generated VAT numbers registered?
No. Numbers follow correct format rules and may pass check-digit validation, but they are not registered with any tax authority.
Which countries are supported?
The generator supports all EU member states, the UK, Switzerland, Norway, and other countries with VAT systems.
Can these be used on real invoices?
No. Using a fake VAT number on commercial invoices is illegal. These are exclusively for software testing and development.
