+.. note::
+
+    For convenience, the IBAN validator accepts values with various types of
+    whitespace (e.g., regular, non-breaking, and narrow non-breaking spaces),
+    which are automatically removed before validation. However, this flexibility
+    can cause issues when storing IBANs or sending them to APIs that expect a
+    strict format. To ensure compatibility, normalize IBANs by removing
+    whitespace and converting them to uppercase before storing or processing.
