Frequently asked questions

How do I check the length of an IBAN from Belarus?
Remove spaces and count 28 characters. The first two characters are BY; the remaining positions follow BYkk BBBB AAAA CCCC CCCC CCCC CCCC. A different length is formally invalid for this country format.
What do the check digits in a Belarus 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.
