IBAN structure with this code

A Swiss IBAN is CH, two check digits, the five-digit IID, then a twelve-digit account part. When the institution holds a QR-IID, the QR-IBAN of a QR-bill carries that number in the same position.

CH31 0866 0000 0000 0000 1

Synthetic example: the account part is a placeholder, this IBAN belongs to nobody. It shows where the code sits inside the IBAN.

QR-IID 30250: a QR-IBAN with this number expects a QRR reference on the QR-bill.
