What the API checks on a Poland IBAN

• The length, the charset of every field and the mod-97 check digits.
• The bank code against our composite map assembled from BIC directories: a BIC and a bank name when they are listed, without the weight of a national register.
• The country's SEPA reachability and the open schemes (SCT, SDD).
• The Verification of Payee duty that does, or does not, bind the country's providers.
