A checksum that passes says the IBAN is well formed, nothing more: it does not confirm that the account exists, is open, or belongs to anyone. National check digits that sit inside the BBAN, where a country has them, are listed but not recomputed here. Every example on this page is synthetic and marked as one, because publishing real-looking account numbers helps nobody.
