## 描述

**ZeroV99 Tax Number** is a WooCommerce extension that seamlessly integrates a **
Tax Identification Number (TIN)** field into your store’s checkout process and billing
addresses.
 Designed for businesses that need to collect valid tax IDs (such as 
NIF, CIF, VAT, or similar) for invoicing, tax compliance, or B2B transactions.

### Features

Tax Number Field Integration
 ✔ Adds a configurable tax identification field (TIN)
to the WooCommerce checkout. ✔ Displays the field in billing addresses (customer
account + admin order view). ✔ Compatible with both individuals and businesses (

Data Management & Compliance
 ✔ Stores tax IDs as order meta and user meta for invoicing
and compliance. ✔ Includes a full uninstall script (removes all plugin data: meta,
options).

Flexibility & Compatibility

✔ Elementor-compatible – no conflicts with page builders. ✔ Multi-language ready(
includes .pot file for translations).

Customization
 ✔ Custom placeholder text for the TIN field (via plugin settings).
✔ Custom billing order fields (vía pluign settings).
