I'm curious if native Italians or experienced expats can shine any light on this.
I recently bought some opera tickets via VivaTicket and was shocked when, during the checkout process, I was asked for my passport number.
I mean, why on earth would a theater care what my passport said? Also, strangely this seems intended for Italians -- when I clicked around on the country of origin, there was an option allowing me as an American to select another field, and bypass that step -- I simply entered "American" or something, I don't remember.
Is it common to be asked to identify yourself to such a specific degree just to make an online credit card purchase?
