In Finland, this would be enough to get you through the security checks at pretty much any institute via phone, possibly excluding banks.

Finland uses whatever the equivalent of a SSN is as a password, US style?

		Kind of. It's advised to keep it secret but I'd be astonished if most people haven't had it leaked whether they realise it or not. Usually when identifying with e.g. a telecoms provider you would give your SSN and then some additional piece of meta-data such as address. Chances are everyone has a combination of SSN + address + phone leaked.
