> No, the number is just a number, and as said it is not secret and can be generated (though with not a 100% guarantee of it being valid because of "total" homonimy). True. I had already forgotten that. Created mine a couple of years ago using some unofficial online service. Maybe I still have it on some disk... Of course I cannot be 100% sure that it is correct. I understand I could order mine officially without ever having lived in Italy. Never bothered about that, I don't have that much contact to Italy.
