Checkout blocks

What you’re seeing: VAT validation behaves differently when your checkout uses WooCommerce Checkout Blocks.

Quick checks

1. Update the plugin to the latest version
2. Test in an incognito window (to avoid cache)
3. If needed, temporarily test with classic checkout to compare behaviour

Compatibility checklist

• •Keep WooCommerce updated (Checkout Blocks change often)
• •Disable checkout field editor plugins temporarily to test conflicts
• •Make sure the VAT field is enabled in EU VAT Checker → General Settings
