About VAT numbers
A Value Added Tax (VAT) number is a unique identifier assigned to businesses registered for VAT in the EU, UK, and many other countries. Businesses must quote their VAT number on invoices, and trading partners often need to validate these numbers for compliance.
Each EU country has its own VAT format: Germany uses 9 digits (DE + 9), France uses a 2-character key + 9 digits (FR + 11), and so on. The Versys VAT checker validates format and checksum for all EU/EEA member states plus the United Kingdom.
