1.4 Why the IBAN validation does not work for my country?

Not all countries have integrated the IBAN system, your country may not support it.
However, please do let us know, so we can investigate and provide you with more details.

1.5 How reliable is it?

The check digit algorithms are extremely accurate way to detect typing errors and verify the integrity of an IBAN.
By performing additional layers of validation such as bank code database lookup, structure and formatting check we decrease the chance of an error to a minimum.
Our bank code database is compiled from multiple official sources (central banks, financial institutions, regulatory bodies etc.) and is updated regularly.
