How the Twilio Phone Number Validation API can be used to quickly validate phone numbers in database

The Twilio Phone Number Validation API can be used to quickly validate phone numbers in a database. This is done by checking the number against a list of known valid numbers and then passing it through a series of validation algorithms. The results of these checks are returned in real-time, so you can be sure that your database contains only valid phone numbers. In this tutorial, you’ll learn how to use the Phone Number Validation API with a Sinatra backend to check credit card numbers against known valid numbers. While the focus of this tutorial is on validating phone numbers, the same techniques can be applied to other API calls to validate other types of data.
