This is no problem at all!
If you do not have the possibility to print the return documents, use the following option:
Use the QR code!
In addition to the actual return label, you will also find a so-called QR code on the return documents. This is located on the left side, which has the heading "Shipment information for your documents".
Show this QR code on your smartphone at a DHL branch, a parcel store, at your parcel delivery service or at a DHL Packstation. DHL will print out the label for you. Please carefully remove old shipping labels and barcodes beforehand.
Simply show the QR code on your smartphone at the Post AT branch counter or print the label at the franking machine in the self-service zone.
