Global Model Number (GMN)

The GMN is the GS1 key used to identify a grouped family of products or a model.

The Global Model Number enables companies to uniquely identify the product model through the entire life cycle of the product: design - production – procurement – use – maintenance - disposal.
 
Examples of where the Global Model Number might be used include products that are sold under different versions, with different colours or supporting languages, but otherwise technically are the same. Other examples include medical devices, for which conformity assessment can take considerable time and effort before a product can be released on a market.
 
In the European Union (EU), the GMN supports the implementation of the requirements of the Basic UDI-DI under the EU Unique Device Identification (UDI) regulations on medical devices and in-vitro diagnostics devices.
