The so-called PZN (Pharmaceutical Central Number) is a unique 8-digit number that can be found on the packaging below the barcode of most pharmacy products. This number varies depending on the active ingredient, active ingredient strength, manufacturer, dosage form, and package size. You can use this number, for example, to ensure that you reorder exactly the same medication. Search via a PZN is also possible in our app and on our webshop.
