It was created for the Single Euro Payments Area (SEPA) to make financial transactions simpler and more secure. In Belgium, as in the entire SEPA zone, the IBAN ensures fast, secure and accurate transfers.</p><p>Your IBAN is a unique alphanumeric sequence linked to your account. In Belgium, it consists of 16 characters. It includes the country code (BE), two check digits, your bank code and your traditional account number.<br />The check digits play a key role. They are calculated using an algorithm that verifies the validity of the IBAN even before a transfer is initiated. This significantly reduces the risk of failed transactions.</p>"}},{"componentType":"paragraph","title":"How to use the IBAN calculator ?","richBody":{"value":"<p>All you need to do is enter your Belgian account number in the field below and clic on &quot;Calculate&quot;.
