GS1 Company Prefix Identification

For Unique Identification of Medical Devices

Across the supply chain, unique product identification is the basis for efficiency and visibility. This identification is even more imperative when it comes to healthcare products, like medical devices, to help increase patient and consumer safety. That is why the U.S. Food and Drug Administration (U.S. FDA) established the unique device identification (UDI) system to adequately identify medical devices sold in the United States.

The U.S. FDA requires GS1 US, a UDI accredited issuing agency, to indicate if a GS1 Company Prefix will or will not be used to identify a medical device.
