One of the most useful convergences in modern healthcare logistics is also one of the least discussed: the same barcode that a hospital’s supply chain uses to order and receive a product can also serve as the device-safety identifier that regulators and registries depend on. That convergence runs through GS1 standards and the FDA’s UDI system.
The shared identifier
GS1’s Global Trade Item Number (GTIN) is one of the identifier systems the FDA accepts as the device-identifier portion of a UDI. In practice that means a single GS1 DataMatrix barcode, encoding a GTIN plus production data such as lot and expiration, can simultaneously satisfy supply-chain identification and UDI labeling. One scan, two jobs.
Locations and shipments, too
GTIN identifies the product, but GS1’s family of identifiers goes further. The Global Location Number (GLN) uniquely identifies a physical or functional location — a specific receiving dock, a particular nursing unit — and the Serial Shipping Container Code (SSCC) identifies a shipment unit. When manufacturers, distributors, and hospitals all use the same identifiers, ordering, receiving, and traceability data can flow without translation between each party’s private codes.
Why the overlap is valuable
Historically, supply-chain identity and clinical/regulatory device identity lived in separate worlds, each with its own codes. The UDI rule’s acceptance of GTIN as a device identifier collapsed that gap for products labeled accordingly. A nurse scanning an implant at the point of use can capture an identifier that feeds the patient record, the recall system, and the inventory ledger at once.
The capture challenge
The remaining work is point-of-use data capture — ensuring the scan actually happens and the captured identifier lands in the right systems. That requires scanning workflows, fields in clinical documentation that can hold UDI data, and exchange standards that carry it forward. AzHeC’s Standards work area covers GS1 and UDI in plain language, and our Connected Devices coverage addresses how device data reaches the EHR. The barcode is ready; the workflows are where the value is won or lost.
