by "unknown numbers", I mean "not at my address book", which is pretty small. So this excludes my bank's security department - why would it be there?

And if scammer spoofs my friend's number, I should be able to recognize it's not my friend, or at least understand thar my friend won't need my bank code.

(Sadly modern phones don't make it easy to tell if the label is from your address book or from external syatem. Adding personal prefixes to end of names, like "John (from NY2020 party)" helps a lot with this.)
