WooCommerce EU VAT Number
This extension provides your checkout with a field to collect (and validate) a customers EU VAT number if they have one. Upon entering a valid VAT number the business (optionally businesses outside of your base country) will then not be charged VAT at your store.
The plugin validates VAT numbers using the handy European VAT Number Validation API.
