Proxeuse is based in the Netherlands and thus part of the European Union's internal market. Therefore, we currently only accept tax numbers that are accepted within that internal market. These are the 27 member states of the EU and Northern Ireland (XI). In your profile, you can specify multiple VAT numbers. For example, if you are registered in multiple member states.
Are you from outside the European Union or Northern Ireland? Then unfortunately you cannot yet provide us with your VAT number. We are working to make this possible.
