Croatia IBAN
21 characters: the country code, two check digits, then the BBAN cut as below.
Anatomy of the official example
HR1210010051863000160
- 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.
| ISO code | HR |
|---|---|
| Length | 21 characters |
| Check digits | positions 3 to 4, ISO 7064 mod 97-10 |
| Bank code | positions 5 to 11 · 7!n |
| Account number | positions 12 to 21 · 10!n |
| Official example | HR12 1001 0051 8630 0016 0 |
| SEPA area | member · SCT, SDD, SCT Inst |
| Verification of Payee | mandatory for the country's providers |
| Bank-code register | IBANforge composite map, assembled from BIC directories (not a national register) |
SWIFT notation: n = digits, a = upper-case letters, c = alphanumeric characters; the exclamation mark fixes the exact length.
What the API checks on a Croatia 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.
