Unique Device Identification (UDI) is a key requirement under the EU Medical Device Regulation (MDR) and the In Vitro Diagnostic Regulation (IVDR). For MedTech manufacturers, UDI compliance means correctly assigning and managing product identifiers and registering them, along with the associated master data, in EUDAMED. But what exactly do you need to stay compliant? In this article, we outline the essential steps, common challenges, and how the mytracekey UDI Manager can make the process significantly easier.
Why UDI Compliance Matters
UDI improves traceability and patient safety, which is why it is being adopted globally. While the U.S. has had a UDI system in place for years, the EU, Australia, and Switzerland are now making UDI data management mandatory in their central databases in 2026.
Failure to comply with EU regulations can lead to restricted market access and penalties. After the transition periods end (May 28, 2026, and November 28, 2026), unregistered medical devices cannot be sold in the EU.
The MDR/IVDR requires all medical devices and IVDs to be registered in EUDAMED with accurate UDI data and related product information.
UDI Basics: The Difference Between Basic UDI DI and UDI DI
A fundamental step toward achieving EUDAMED UDI compliance is understanding the different types of UDIs. Because of similar names, confusion between Basic UDI DI and UDI DI is a common misunderstanding.
The Basic UDI DI identifies a group of medical devices that share the same intended purpose. That is risk class, and essential design characteristics. It serves as a higher-level identifier for a device family.
The UDI DI, on the other hand, identifies a specific device or device model. It serves as the reference for the product data stored in EUDAMED and forms the basis for the traceability of a medical device throughout its entire lifecycle.
In other words, the Basic UDI DI describes a device family, while the UDI DI identifies a specific product within that family. A manufacturer can therefore assign multiple UDI DIs to a single Basic UDI DI when different product variants or models exist within the same device family.
Example: A manufacturer markets medical compression stockings. Since all variants share the same intended purpose, risk class, and essential design characteristics, they can be grouped under a single Basic UDI DI. However, several product variants exist within this family, each requiring its own UDI DI:
- UDI DI 1: Compression stocking, black
- UDI DI 2: Compression stocking, white
- UDI DI 3: Compression stocking, beige
In this example, the Basic UDI DI remains the same for all three products because they belong to the same device family. The individual UDI DIs distinguish the specific variants from one another and enable their unique identification. Even a difference in color can be sufficient to require the assignment of a new UDI DI.
Key Requirements for UDI Compliance
- Assigning UDI Codes
UDI codes based on GS1, HIBCC, IFA, or ICCBBA standards have been mandatory for all product classes since 2025. These codes must appear on labels and packaging and serve as the link to additional data stored in EUDAMED. - Collecting Product Master Data
EUDAMED requires various mandatory attributes depending on the product, such as Basic UDI-DI, UDI-DI, risk class, target markets, product name and model, and details on sterility or reusability.
Before submission, UDI data should be validated against EUDAMED business rules to avoid errors and potential recalls. - Registering in EUDAMED
All UDI data must be uploaded to the UDI module in EUDAMED, forming the basis for other modules such as certificates linked to products via UDI. Upload options include manual entry, XML bulk upload, or automated transfer via M2M integration.
Any data changes must be updated in EUDAMED, and some changes require a new UDI-DI. MDR demands a structured process for managing UDI throughout the product lifecycle.
Common Challenges for Manufacturers
- Complex Data Requirements: Hundreds of attributes per product.
Many manufacturers have data scattered across folders, systems, and teams. Issues often arise when trying to validate data against EUDAMED rules. Depending on the product, more than 100 attributes may be mandatory. - Manual Processes: High risk of errors and delays.
Manual UDI management may work for small portfolios, but with growing complexity, manual entry becomes error-prone and time-consuming. - Regulatory Updates: Continuous changes to MDR and EUDAMED.
Both MDR/IVDR and EUDAMED are evolving. Manual processes struggle to keep up and may not be audit-ready. UDI requirements are not set in stone, so expert guidance is highly recommended.

Next Steps for Manufacturers
The most important first step is to take stock. Check your current UDI readiness. Do you have all your product data together? Do you know which upload strategy is right for you? Have you already entered a UDI-DI in EUDAMED on a trial basis? What is missing for you to start the registration process? How long do you estimate it will take? What does your timeline look like?
This leads to the second step: Do you need external support in the form of software, training, or consultants to ensure the timely implementation of your UDI compliance? There are various ways to get support. For example, choose a reliable software solution such as mytracekey UDI Manager to simplify your compliance.
The third step is both simple and complicated, but we wholeheartedly recommend it: Start now.
