How Phone Validator Work?

Real-time Phone Number Validation Tool


  • Phone number validation is the process of checking if a phone number is accurate. It lets you find out if the phone number you have for a customer is active and able to receive SMS, messages, and calls.
  • A free phone validator tool helps you validate phone numbers in your database or web app. By entering the number, you’ll get information on whether the phone number is valid or not, i.e., whether you can send messages or call that number.
  • To validate, find a phone number.

Your application can ask users to enter a phone number in your web forms, or you can identify existing numbers in your customer database.

  • Request the Phone Validator API.

Your application passes the phone number to the Phone Validator API for validation.

  • Validate and gather information.

The Phone Validator API queries multiple information sources and live telco data to validate and gather information about the phone number.

  • Return Information That Has Been Validated

The Phone Validator API returns phone number information to your application, allowing you to remove unreachable numbers and identify valid numbers as landline or mobile.
