From the PZN to PPN
In order to uniquely identify a product assigned with a PZN world-wide, the Pharmacy Product Number (PPN) was created. Thus the PPN also aids verifying medicinal products affected by the Falsified Medicines Directive.
A PZN can easily be transformed into a PPN with a simple algorithm (see PPN Generator). Thus databases do not necessarily have to be updated. The world-wide unique data designator “9N” has been assigned to the PPN according to ISO/IEC 15418/ANSI MH10.8.2.
IFA’s Information Services also contain the PPN.
