About the VAT Number Validator

An intra-community VAT number identifies a business registered for VAT in the European Union. Each country has its own format and almost all include a check digit computed from the rest of the number. This tool applies each country’s official algorithm, so a mistyped or invented number is rejected, not just a badly formatted one.

Features

Real check digit: each country’s official algorithm (mod 97 for France and Belgium, Luhn for Italy and Sweden, ISO 7064 for Germany and Croatia…)
31 countries: the 27 EU member states, Northern Ireland (XI), United Kingdom, Switzerland and Norway
France: the SIREN inside the VAT number is also checked, with a link to the official company directory
Official register: one click to VIES (European Commission), HMRC, the Swiss UID register or Brønnøysund
Free input: spaces, dots and dashes are ignored; GR is accepted for Greece (EL)
Direct link: vat-validator.html?vat=FR40303265045 validates the number on page load
Privacy: the check runs entirely in your browser, nothing is sent

How to use

Type or paste the VAT number, starting with the country code (FR, DE, IT…)
Press Enter or click “Validate VAT Number”
If it is valid, use the official register link to confirm the business is currently registered
Click a country in the list to try a valid example

Valid vs. active

Valid (this tool): the number is correctly built. It catches typos and invented numbers.
Active (VIES or the national register): the business is currently registered for VAT. A valid number can belong to a closed company.
Before invoicing a B2B customer without VAT (reverse charge), check the number on VIES and keep a copy of the result.

Italy: IT + 11 digits (e.g. IT00743110157)
