🧾 Magento 2 VAT ID Validation

A lightweight module that adds client-side VAT ID validation to key Magento 2 forms like checkout and customer address forms.
This is helpful for EU country based commerce, that needs to verify VAT ID via VIES.

📋 Description

This module adds smart VAT ID validation per country, using patterns based on the official EU formats.

Default Magento 2 behavior:
