IBAN Structure Kazakhstan

Last reviewed: · Source: ISO 13616 / SWIFT IBAN Registry

Kazakhstan's IBAN has 20 characters in the format KZkk BBBC CCCC CCCC CCCC. After the country code KZ and the check digits come a 3-digit bank code and the 13-character account number. Kazakhstan is not a SEPA participant. The currency is the tenge (KZT). For international payments, routing details, fees and timing depend on the banks, currency and route; check them in advance with your bank. Kazakhstan is one of the few Central Asian states to have introduced the IBAN in domestic payments.

Frequently asked questions

How do I check the length of an IBAN from Kazakhstan?
Remove spaces and count 20 characters. The first two characters are KZ; the remaining positions follow KZkk BBBC CCCC CCCC CCCC. A different length is formally invalid for this country format.
What do the check digits in a Kazakhstan IBAN mean?
The two check digits are calculated from the complete IBAN using ISO 7064 MOD-97. They help detect format and transcription errors. A passing checksum does not confirm that an account exists or identify its account holder.
What should I do when an IBAN is formally invalid?
Check the country code, character count, letters and digits, and the check digits. Compare the entry with your bank records or ask the bank for the correct IBAN. This checker validates structure and checksum; it does not verify account ownership or payment approval.
