 * Validate phone numbers and retrieve additional information

 * This method serves as an additional layer of protection in your system for validating phone numbers. It not only checks the syntax but also assesses the likelihood of the phone number being valid and operational.

By incorporating this scoring into your workflow, you can enhance fraud detection, reduce invalid inputs, and improve the overall quality of data captured.
