The European Union (EU) Medical Devices Regulation (MDR) and In-vitro Diagnostic Medical Devices Regulation (IVDR) have been adopted on 5 April 2017 and define the requirements for the EU UDI system. The Basic UDI-DI is a new identifier that has been introduced by the Regulations.

The Global Model Number (GMN) is a new key developed by GS1 to support the implementation of the Basic UDI-DI. The GMN generator is used to generate the GMN based on a GS1 Company Prefix and an internal number. This short video will provide a basic overview of the identifier.
