No, the validation process is not carried out using OTP, which means that the phone number owner will not receive any SMS or call for validation of the phone number. The process is carried out using multiple methods which include validation from International Telecom Authority, Multiple Carrier lines, and third party validation tool.

With a multi-level process that covers validation via International telecom authority, multiple carrier lines, and 3rd party validation, we ensure the highest level of accuracy achievable for each number.

Yes, ClearoutPhone supports any type of number: mobile, landline/fixed line, VoIP, etc.

A valid phone number is the one that is issued by any carrier in the world to its users, including satellite numbers. It does not necessarily mean that the number is currently reachable.

We validate phone number across the globe. The association of the phone number with name is not available on this.

The simple & easiest way would be to call up the number & check it up. But obviously we can’t do that if there is bulk data to check. In such cases, I recommend you using our phone number validation tool. We provide 100 Free credits while you sign up. The validation of data can be either instant or bulk verification. We also provide an option to integrate & make API setup with your website. This filters out entry of any invalid contacts in your database. Along with ascertaining the validity of the number, this platform also helps you with information like carrier type, Mobile type, Geolocate , timezone,Formatting etc.To auto verify,the best option will be to use real-time Phone validation API to easily integrate into website forms or mobile apps and make sure only valid numbers are accepted to your contact list and improve overall user experience at the time of capture.
