To place an order with Klarna you need to provide a shipping address registered in Germany and your phone number. It's also important to enter your correct email address as the payment details will be sent to you by email as soon as the order has been shipped from us.
Once you have received the payment details by email, you will also be able to find them in your Klarna account and the Klarna app.
