What the API checks on a Serbia IBAN
- The length, the charset of every field and the mod-97 check digits.
- The bank code against National Bank of Serbia (list of banks participating in the RTGS and clearing systems): 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).
- The Verification of Payee duty that does, or does not, bind the country's providers.
