Carnet de passage, Need Help
 

I am having some difficulty understanding exactly how to go about applying for this "triptiq"

I have ridden from AK to Ushuaia and never had to deal with any of this.

How do I apply for this?

Is it absolutely necessary and to whom do I submit the paper work too?

I am very confused.
