European VAT Validator for WooCommerce

Selling to EU-based businesses through your WooCommerce store?

The European VAT Validator extension helps you stay tax compliant and simplify B2B checkout experiences. With real-time VAT number validation via the official VIES system, you can apply VAT exemptions instantly and accurately based on customer data and location.

This extension is designed to support EU VAT regulations, including VAT OSS and Intra-Community VAT. It allows flexible country-specific tax rates, recognizes VAT numbers by address or prefixes, and can periodically verify stored numbers to ensure long-term accuracy —  ideal for stores operating both B2B and B2C in the European Union.

Main features

• Validate EU VAT numbers in real-time via VIES at checkout.
• Require or allow optional VAT fields based on country or customer type.
• Flexible behavior when VIES is unavailable (still allow orders).
• Automatically recognize VAT prefix from billing address.
• Display clear validation success or error notices on the order page.
• Use your own proxy list to avoid rate limits when sending frequent requests.
• Set up scheduled VAT checks (CRON) for existing customer base.

• Handle intra-community VAT logic and auto-exclude based on delivery country.
• View logs, validation status, and add VAT columns in admin order list.
• Exclude selected countries from VAT modifications (e.g. your base country).
