I’m trying to create a custom Registration theme with 2 forms :  
The first one is a validation form in wich client will put one ClientCode and one ZIPcode  
If both information of the first form are validated then we have the second form a classic one.  
Do you know if it’s possible to do that ?

You could use one form and show/hide the (input) controls.
