VAT / Tax Number Field

VAT / Tax Number combines tax-ID collection with country-aware prefixes, optional VIES validation, and optional WooCommerce tax-exemption logic.

What the customer sees

A tax-number input that can use a full identifier or an automatic country prefix.

What is saved

The normalized tax number and related validation/tax metadata where applicable.

Important settings

  • Input mode
  • Country source
  • Online validation
  • Tax handling
  • Tax exemption countries
  • Invalid-number blocking
  • Country mismatch

Typical uses

  • Business tax ID
  • EU VAT workflow
  • International tax-number collection

Important considerations

  • VIES is not a worldwide tax-ID validator.
  • The merchant is responsible for using tax exemption rules that match the business’s legal obligations.
