How a Bosnia and Herzegovina IBAN is structured
A Bosnia and Herzegovina IBAN is read left to right: a 2-letter ISO 3166 country code (BA), 2 MOD 97 check digits, then a 16-character BBAN. The BBAN is split into 4 fields: 3 digits, 3 digits, 8 digits, 2 digits.

How Bosnia and Herzegovina IBAN check digits work
The two digits at positions 3–4 are a MOD 97-10 checksum computed from the country code and the BBAN. To verify it, the IBAN is rearranged (BBAN first, country code and check digits last), letters are converted to numbers (A = 10, B = 11, …), and the whole integer is taken mod 97. A valid IBAN has a remainder of 1. This catches any single-digit typo and most transposition errors — which is why a one-character mistake is enough to make a Bosnia and Herzegovina IBAN fail validation instantly.
