Phone Number Validation

Make sure you call the numbers you are allowed to

A phone number is arguably the most vital contact point for customers


Why phone number verification is important

There is nothing more frustrating than finding out that someone has submitted an enquiry on your website and the contact number is not valid, relates to a dead number or in the case of mobiles appears to be switched off.

Use Data Soap's phone validator tools on your website or app

Our API’s allow you to validate phone numbers (both mobiles and landlines) in real time when data is entered onto your data capture form. This provides you with a valuable validation tool that ensures that only contactable telephone numbers are collected through your data capture sites.

The phone number validation service works with UK and international numbers for mobile phones, and UK numbers only for landlines.
