European UDI requirements

Compliance time

The European UDI compliance schedule is shown in the figure below. According to the difference in risk levels, the compliance schedules also vary, covering all products under the MDR and IVDR.


The EUDAMED database contains several modules, one of which is the UDI module.




 Implementation of UDI (Unique Device Identification)

1. The UDI shall be located on the device itself or its package, and the higher-level package shall have its own UDI.

2. Transport containers shall be exempt from the requirements of Section 3.1. For example, UDI is not required on logistics equipment; when a medical service organization orders multiple devices using UDI or single device model, and the manufacturer places these devices in a container for transportation or protection of individually packaged devices, UDI shall not be required on the container (logistics equipment).

3. UDI shall consist of two parts: UDI - DI and UDI - PI.

4. UDI - DI is unique on all levels of device package.

5. If the lot number, serial number, software identification or expiration date appears on the label, it will be part of UDI - PI. If the production date is also marked on the label, it is not necessary to include the production date in UDI - PI. If there is only the production date on the label, it shall be used as UDI - PI.

6. Each component that is considered a device and can be purchased on the market shall have its own UDI, unless such a component is part of a configurable device sold under a separate UDI.

7. The system and program package described in Article 22 shall be allocated and shall bear its own UDI. (Traceability)

8. The manufacturer shall assign UDI to the device according to the following coding standards.

9. When it is possible to cause misidentification of the device and/or its traceability is not clear, especially when any of the following changes in the UDI database elements requires a new UDI - DI, the new UDI - DI shall be provided.

10. The manufacturer repackaging and/or reinstalling the device shall use its own labels and keep the UDI records of the original equipment manufacturer (OEM).

3. The method to control the device production (expiration date or production date, lot number or lots, and serial number);

4. If applicable, the “UDI - DI” user (when the UDI “user” is not labeled for the device, the DI “user” shall be specified to link the use of the device to the patient);

5. The manufacturer’s name and address (as indicated on the label);

6. The SRN issued in accordance with Article 31(2);
