I mean, sure, my bank in Norway has my account tied to a person number, but they don't actually know that when I log in with bankid that I really am the person associated with that person number. --Theoretically the post office was supposed to verify my identity before they gave me the packet containing the code brick, but they forgot to do so - this was over 10 years ago before they had to register the ID details.
So basically I have a highly trusted way of authenticating to financial and government services in Norway even though nobody actually knows that I am who I claimed to be when I opened the bank account, setup bankid, etc.
