Only Dutch organizations are required to register with a valid registration number. The platform is linked to the  Dutch Chamber of Commerce website which automatically generates the organization data.

 As a foreign organization it is possible that you do not have a registration number. 

To register successfully, enter a fictitious number, letters or a combination of these in the 'Registration Number' field. Example: 123HG4

Click on then Search and Verify, you will see that you can enter other details of your organization.

You can succesfully register your organization.
