Kazakhstan IBAN

Anatomy of the official example

KZ86125KZT5004100100

• Country code
• Check digits
• Bank code
• Account number

The example comes from the ISO 13616 registry; it belongs to nobody. Positions count from the first character of the IBAN.

What the API checks on a Kazakhstan 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.
