A VAT (Value Added Tax) identification number is a unique identifier used by businesses in the European Union for tax purposes. Each EU member state has its own format with a two-letter country prefix followed by a variable-length numeric code.

VAT numbers are essential for cross-border trade within the EU and are used for:

• Identifying businesses for VAT purposes
• Validating transactions on invoices
• Claiming VAT refunds on business expenses
• Verifying EU trading partners
