The network validation feature of our phone block automatically checks for you if the number your flow visitor has entered is registered with a legitimate carrier.

Like that, you can easily improve the accuracy and validity of contact information and increase lead quality.

How does it work?

  • Whenever one of your flow visitors enters a phone number into the phone block, our system will automatically check whether it’s registered with a legitimate phone carrier. If the phone number cannot be verified, visitors will not be able to further progress in your flow.
    ​

  • This service is generally available worldwide. We can guarantee it to work for all carriers for the DACH region (Germany, Austria, Switzerland), the UK, USA and Canada. In other countries, major carriers should always be supported, with some smaller ones not returning a result. Landline numbers can't be network validated, therefore, they just pass the validation.
    ​

  • The first 10 validations per month are free (120 per year for annually billed plans). After that, the cost per validation is 0.04 Euros/ 0.044 USD. The total of all validations within a billing period will be added to your bill. You can always check your total for your current billing period in the “Modules” tab.
