Uniquely identify product models using a GMN
The GS1 Global Model Number (GMN) is used to identify a product model or a product family. This is based on characteristics defined by the supplier or in accordance with legislation.
The GMN may not be used to identify a product. Once assigned, it may not be reused to identify another family.
For regulated healthcare medical devices, the GMN is the GS1 identification key to support the implementation of the Basic UDI-DI.
The GMN contains the company prefix, a model/family reference and 2 check digits.
