In this article, you will learn what to do if you did not provide the reference number with a bank transfer.
In most cases, we can still assign your payment despite the missing reference number. You can check whether your transfer has reached us in our payment portal (customer portal). To view the portal in English, simply switch from DE to EN in the top right-hand corner.
If there are still outstanding claims and your transfer was made several days ago, you can send us a payment receipt via the digital assistant at the bottom right of this page. After receipt, we will review the process.
