Frequently asked questions

How do I check the length of an IBAN from Slovenia?
Remove spaces and count 19 characters. The first two characters are SI; the remaining positions follow SIkk BBSS SCCC CCCC CKK. A different length is formally invalid for this country format.
What do the check digits in a Slovenia 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.
