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.

  • Landline numbers can't be network validated, therefore, they just pass the validation.


Initial setup

  1. Add the phone number block to your heyflow.

  2. Click on the block to open the block settings.

  3. In the tab “Modules”, click on “Enable Module” to activate the network validation.

  4. A window with pricing and billing information will open, confirm your choice by clicking on “Enable paid module”.

  5. Enable the network validation on the specific block and supply an error message for failed validations.

  6. Publish your heyflow.

Once you have initially activated this module, you can add it to any other heyflow by enabling network validation in the “Validation” tab in the block settings.


How to disable the network validation for individual heyflow

  1. Click on the phone block within the relevant heyflow.

  2. In the block settings, scroll to the “Validation” tab and unselect the network validation checkbox.

  3. Repeat this process for all phone blocks that are used in your heyflow.

  4. Publish your heyflow. The network validation will remain active until your heyflow has been re-published.


How to disable the network validation for all heyflows

  1. Click on your credentials in the top right corner and then go to “Modules”.

  2. Here select “Disable module” next to “Phone number network validation”.

  3. A pop-up window will open. Confirm your choice by clicking on “Disable module”.

Please note: When you enable the network validation again after you have disabled it via the Modules tab, it will automatically be enabled for all flows it has been activated for previously.
