What the API checks on a Seychelles 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 is outside SEPA: a SEPA transfer will not reach this account.
