for those of you who wonder what is the codice fiscale, it's a computer-generated combination of your mane,sex,date and place of birth plus a check digit. Generating programs are easily available (many people forget it and financial offices can re-generate it on the spot) but forging one which is not officially registed at the IRS is like printing you own ID card! The code is usually required for financial transactions with Italian citizen, that's the reason why Trenitalia asks for it. Bye all
