What the API checks on a Greece 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, SCT Inst).
  • The Verification of Payee duty that does, or does not, bind the country's providers.
