You can use the new, scannable pick-up code right away. To do this, update the Post & DHL App and enable your smartphone in the app (this is a one-off process).
As an existing Packstation customer, at the moment you can still pick up your parcels using your customer card and four-digit pick-up code at the Packstation, should you wish to. Soon, you will only be able to receive the pick-up code via the Post & DHL app. For security reasons, you will no longer receive an e-mail with your pick-up code.
Please note: As soon as you have enabled your smartphone for the scannable pick-up code, you will only be able to use the new method and will receive the pick-up code exclusively in the app, not by e-mail.
