What UDI-PIs should be included in the UDI under EU MDR and IVDR?

Modified on Wed, 28 Aug at 8:24 PM

The European Commission may, by means of implementing acts, specify the data to be included in the UDI-PI of specific devices or device groups. Please remember that the manufacturer is responsible for assigning a risk class to its devices, not GS1.


The EU MDR and IVDR have defined a few principles concerning UDI-PIs:


  • If a lot number, serial number, software identification or expiry date appears on the label, it shall be part of the UDI-PI. If there is a manufacturing date on the label, it does not need to be included in the UDI-PI. If there is only a manufacturing date on the label, this shall be used as the UDI-PI
  • Serial number is a mandatory UDI-PI for active implantable devices
  • Serial number or lot number is a mandatory UDI-PI for other implantable devices
  • The software identification shall be considered to be the manufacturing control mechanism and shall be displayed in the UDI-PI. Minor software revision shall require a new UDI-PI and not a new UDI-DI
