| Bank-code register | IBANforge composite bank-code map (assembled from BIC directories, not a national bank-code register) |
SWIFT notation: n = digits, a = upper-case letters, c = alphanumeric characters; the exclamation mark fixes the exact length.
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 IBANforge composite bank-code map (assembled from BIC directories, not a national bank-code register): the holder of every code it lists, without the weight of a register that settles a negative; the other codes against our composite map.
- 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.
What the API answers for this code
The API checks this country's bank codes against IBANforge composite bank-code map (assembled from BIC directories, not a national bank-code register). We serve that register from a private file rather than publish it, so its answer to this example is not copied here: it is computed live, on the request. Try the example in the playground
