Heared a case of a guy who was turned down even if he had CF printed on the residence permit which was plastic and valid, they insisted on tessera sanitaria or this CF card and would not "trust" the police/Questura issued document lol.
Was needed to get a local SIM card. So not refused by a bank or some gov insitution....refused by a simple shop for a SIM card lol
I got a CF number issued by TIM when purchasing a prepaid SIM card back in 2011. Number was actually valid (validated using various CF online calculators), and calculated as a foreigner (I'm not Italian and don't live there). Even successfully used it to open a Hype online bank account a few years ago (which they subsequently blocked/closed a few months later - not sure why, maybe because of my non-EU citizenship

Also heard about the various lawyers/introducers who supposedly can help open a bank account in Italy (as a prospective real estate buyer), although not sure what others have experienced.
And back to the topic...the last time I tried to get a BlackcatCard in late 2021, I got a Gekkard card instead. Same company (Papaya in Malta), same type of IBAN: MTxxx, I just didn't get that cool black card...
