The NIF Num. de Contribuinte Português for WooCommerce plugin enriches the WooCommerce checkout experience by adding a dedicated field for the Portuguese VAT identification number (NIF/NIPC). This feature is specifically designed for stores serving customers in Portugal, allowing for seamless integration into the checkout process. The plugin not only displays the NIF/NIPC field during checkout but also includes it in order details, emails, and the 'Thank You' page, ensuring that both customers and store administrators have easy access to this important information.

Additionally, the plugin supports editing the NIF/NIPC field through the 'My Account – Billing Address' section and the user edit screen in the WordPress admin. It also offers check digit validation for the NIF/NIPC field, enhancing data accuracy. Compatibility with WooCommerce High-Performance Order Storage and the Checkout Block (currently in beta) further extends its functionality, making it a valuable tool for any WooCommerce store looking to comply with Portuguese tax regulations.
