 A simple and clean PHP class that validates EU VAT numbers against the central ec.europa.eu database (using the official europa API).
 
 
+## The Problem
+
+Validate VAT numbers might be difficult and if you use a validation pattern to check if the format is valid, you are never sure if the VAT registration number is still valid.
+
+## The Solution
+
+This [PHP VAT validator library](https://github.com/pH-7/eu-vat-validator) uses real-time data feeds from individual EU member states' VAT systems so you are sure of the validity of the number and avoid fraud with expired or wrong VAT numbers.
+
+For example, this kind of validation can be very useful on online payment forms.
