Unique device identification

The UDI is composed of two parts: DI + PI = UDI.
Device identifier (DI) + production identifiers (PI) = unique device identifier (UDI).
Device identifier (DI): A mandatory, fixed portion of a UDI that identifies a manufacturer’s specific product and package configuration.

For Medtronic, this is the GS1 Global Trade Item Number (GTIN); and production identifier (PI): a conditional, variable portion of a UDI that identifies one or more of the following when included on the package label of the device:

• The lot or batch within which a device was manufactured
• The serial number of a specific device
• The expiration date of a specific device
• The date a specific device was manufactured

Check the label. All Medtronic devices in the global supply chain have the UDI encoded in a GS1-128 barcode format on the product package.

Review order and shipping documentation. Medtronic invoices (both electronic and paper) and delivery notes (shipping documents) include the UDI in human readable format (GTIN = device identifier and lot or serial number = production identifier).

Contact your purchasing organization or Medtronic customer service. Medtronic customer service can provide the UDI information, e.g., device identifier (GTIN) and production identifiers (lot or serial number) for a particular product ordered. In addition, most electronic data interchange (EDI) transactions will also have the UDI included in the messaging format.
