EU Medical Devices Regulations – Unique Device Identifier (UDI)

Last updated: 30 August 2023


The new EU medical device regulations (MDR) were adopted by the European Union in April 2017 and came into force in May 2017. The application dates of these regulations apply as of May 26th, 2021 for medical devices and May 26th 2022 for IVD. The requirements that are currently laid down, might result in congestion and prolong the process. If companies provide inaccurate MDR compliant labeling, they will not be able to distribute their products in Europe. These challenges might lead to increased costs or increasing stockpiles of products. 

In addition to the EU Medical Device Regulations (EU MDR), the EU further introduced an identification system that is based on a Unique Device Identifier (UDI) to facilitate easy traceability, enhanced post-market surveillance, better documentation and monitoring of safety-related activities for the devices.  (Source: International Medical Device Regulators Forum (IMDRF):


What is a Unique Device Identifier (UDI) and where is it applicable?


Unique device identifier (UDI)  is a series of numeric or alpha-numeric codes created through a globally accepted device identification and coding standard. UDI is comprised of the following:

UDI-DI (UDI- Device Identifier) is used to identify the group of devices that fall under the same category of risk, intended purpose, essential design and other manufacturing characteristics in EUDAMED. The UDI - DI  is composed of the following ;
  • Version/model of the product
  • Labeller of the product
  • Quantity in the package (i.e. the unit of sale or  multi-pack)
  • Issued by your agency

UDI-DI is mentioned in the relevant documents such as technical documentation, certificates of safety and clinical performance, EU declaration of conformity and not the device itself.

UDI-PI (UDI- Production Identifier) is an alpha-numeric code that is created to identify the unit of the device production.  The UDI-PI is composed of the following;

  • Conditional, variable
  • Identification of lot/batch number, serial number, software Identification, expiration date, manufacturing date (if no expiration date) is included on the device label


Action Items your Unique Device Identifier (UDI) should include

  • Part numbers should be assigned to your finished products. These are always issued by a neutral party. 
  • Packaging of the specific product must have a UDI label. 
  • Some of the products must also bear the UDI label 
  • Register the UDI in EUDAMED for easy tracking. 


Location of the Unique Device Identifier (UDI) symbols

  • UDI must appear in both human-readable information and a form that uses AIDC
  • UDI carrier shall be placed on the device itself or on the packaging of the product
  • If the product cannot have both the AIDC and HRI, then the device should only have the AIDC
  • 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 also 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


Unique Device Identifier (UDI) Issuing Entities in Europe

The designated entities listed by the commission for issuing the UDIs are

  • GSI AISBL in Belgium
  • HIBCC – Health Industry Business Communications Council
  • ICCBBA – International Council for Commonality in Blood Banking Automation
  • IFA GmbH – Informationsstelle für Arzneispezialitäte
