VAT ID in Checkout

The module adds fields for entering Company ID (IČ), Tax ID (DIČ) and VAT ID to the WooCommerce checkout. It also enables validation of these details using ARES and VIES services and automatic VAT exemption.

Module Features

• Add Company ID, Tax ID and VAT ID fields to checkout
• Hide business fields under “I’m buying as a company” checkbox
• Move Company field to business details
• Configure field appearance and requirements
• Automatic address filling from ARES database
• Company ID validation via ARES
• Tax ID validation via VIES
• EU Reverse Charge (zero VAT for EU companies)
• Third country export (zero VAT outside EU)

Module Activation

1. Go to WPify → WPify Woo
2. Enable the VAT ID in Checkout module
3. Save changes

After activation, a link to the module settings will appear at the top of the page.

Block checkout compatibility

The module fully supports WooCommerce block checkout. Some visual settings (e.g., half-width fields, moving to the beginning of the form) are only available for classic checkout, as block checkout has its own layout system. However, module functionality is fully preserved.
