VAT Number Validator

A Value Added Tax (VAT) number is a unique identifier assigned to businesses registered for VAT in the European Union and several other countries. It is used on invoices for cross-border B2B transactions within the EU.

Format Validation vs. Existence Verification

This tool validates the format of a VAT number — checking that it matches the pattern required by the issuing country. It does not verify that the business is currently registered (that requires a live check against the EU VIES database).

Coverage

Supports all 27 EU member states, the United Kingdom (post-Brexit), Norway, and Switzerland — 30 countries in total.

Auto-Detection

Simply type or paste the VAT number including its country prefix (e.g., DE for Germany, FR for France). The tool automatically identifies the country and applies the correct validation pattern.
