Introduction

Switzerland maintains an independent regulatory framework for medical devices and in vitro diagnostic medical devices under the Medical Devices Ordinance (MedDO) and In Vitro Diagnostic Medical Devices Ordinance (IvDO). While these regulations remain closely aligned with the European Union’s MDR and IVDR, manufacturers placing devices on the Swiss market must comply with Switzerland’s own regulatory requirements, oversight by Swissmedic, and device registration obligations through the swissdamed database.

At the center of this framework is the Unique Device Identification (UDI) system, which provides standardized device identification to support traceability, market surveillance, and post-market safety activities. As swissdamed continues its phased implementation, manufacturers must understand not only how UDI requirements align with the EU, but also the Swiss-specific processes for economic operator registration, device registration, and ongoing regulatory data management.

This article provides a practical overview of Switzerland’s UDI framework, explaining the purpose of the regulations, stakeholder responsibilities, swissdamed requirements, compliance obligations, and the role of trusted product data in supporting long-term regulatory compliance.

The Strategic Purpose of Switzerland’s UDI Framework

Switzerland’s UDI framework is intended to strengthen the identification and traceability of medical devices throughout their lifecycle while supporting effective regulatory oversight within the Swiss market. Although the framework closely follows internationally recognized UDI principles developed by the International Medical Device Regulators Forum (IMDRF), Switzerland administers these requirements independently through Swiss legislation and Swissmedic.

The implementation of swissdamed provides the digital infrastructure to support these objectives by enabling the registration of economic operators and medical devices, improving regulatory transparency, and strengthening coordination between manufacturers, Swissmedic, and other stakeholders.

The primary objectives of Switzerland’s UDI framework are to:

• Enhance device traceability: Enable consistent identification of medical devices throughout the supply chain and across post-market activities.
• Support patient safety: Improve the efficiency of recalls, field safety corrective actions (FSCAs), and vigilance reporting through standardized device identification.
• Strengthen market surveillance: Provide Swissmedic with accurate regulatory data to support monitoring of devices placed on the Swiss market and facilitate coordinated regulatory oversight.
• Align with international standards: Maintain compatibility with globally recognized UDI principles while supporting Switzerland’s independent regulatory framework and national device registration requirements.

Scope and Stakeholder Responsibilities

Switzerland’s UDI requirements apply to medical devices and in vitro diagnostic medical devices placed on the Swiss market in accordance with MedDO and IvDO. While the regulatory framework is largely aligned with the EU MDR and IVDR, manufacturers must comply with Swiss-specific obligations for economic operator registration, market access, and device registration.

The regulations establish responsibilities across the supply chain:

• Manufacturers: Responsible for assigning UDIs, ensuring compliant device labelling, maintaining technical documentation, registering devices in swissdamed, and fulfilling post-market obligations throughout the product lifecycle.
• Swiss Authorized Representatives (CH-REP): Manufacturers established outside Switzerland must appoint a Swiss Authorized Representative. The CH-REP serves as the manufacturer’s regulatory representative in Switzerland and assumes responsibilities defined under MedDO and IvDO.
• Importers: Responsible for verifying that devices entering the Swiss market meet applicable regulatory requirements, including the presence of required economic operators and compliant labelling.
• Distributors: Responsible for verifying that devices continue to comply with applicable regulatory requirements before making them available on the Swiss market.

Unlike the European Union, where many regulatory processes are managed through EUDAMED, Switzerland operates its own regulatory database called swissdamed. Manufacturers placing products on both the EU and Swiss markets should therefore expect to maintain separate regulatory registrations and ongoing lifecycle management activities, even where much of the underlying product data is common between the two jurisdictions.

Key Regulatory Identifiers for the Swiss Market

Switzerland’s regulatory framework uses several identifiers to uniquely identify economic operators, device families, and individual device models. Most device identifiers align with internationally recognized UDI standards, while Switzerland also introduces identifiers that support its own regulatory processes.

• Swiss Registration Number (CHRN): The CHRN uniquely identifies economic operators registered with Swissmedic, including manufacturers, Swiss Authorized Representatives (CH-REPs), importers, and system or procedure pack producers. The CHRN serves as the primary identifier for regulatory interactions with Swissmedic and swissdamed.
• Basic UDI-DI: The Basic UDI-DI is an administrative identifier that groups devices sharing the same intended purpose, risk class, and essential design and manufacturing characteristics. It links a family of devices to technical documentation, declarations of conformity, and conformity assessment records, but does not appear on the device label.
• UDI-DI: The UDI-DI uniquely identifies a specific device model and forms the basis for device registration within swissdamed. Manufacturers are responsible for assigning and maintaining UDI-DIs throughout the product lifecycle. Changes affecting device identification or traceability generally require assignment of a new UDI-DI.
• UDI-PI: The UDI Production Identifier (UDI-PI) captures production-specific information such as lot number, serial number, manufacturing date, expiration date, or software version, where applicable. While essential for device traceability and post-market activities, the UDI-PI is carried on the product label rather than being maintained as part of the core device registration record in swisssdamed.

swissdamed Device Registration

swissdamed is Switzerland’s national database for medical devices and in vitro diagnostic medical devices. Developed and operated by Swissmedic, it supports the registration of economic operators and devices while strengthening market surveillance and regulatory oversight within Switzerland.

The database is being introduced through a phased implementation. The Actors module enables the registration of manufacturers, Swiss Authorized Representatives, importers, and other economic operators, while the UDI Devices module supports the registration of medical devices, IVDs, and systems and procedure packs.

For manufacturers marketing devices in both the EU and Switzerland, it is important to recognize that EUDAMED and swissdamed are independent regulatory systems. Device information submitted to EUDAMED is not automatically transferred to swissdamed. Manufacturers are responsible for maintaining separate regulatory records while ensuring consistency across product labelling, technical documentation, and both regulatory databases.

High-Level Obligations for Swiss UDI Compliance

Achieving compliance with Switzerland’s UDI framework requires manufacturers to establish governance processes that maintain accurate regulatory data throughout the product lifecycle. Key obligations include:

• UDI Assignment: Assign Basic UDI-DIs, UDI-DIs, and UDI-PIs using an accredited issuing entity and maintain identifier integrity throughout the product lifecycle.
• UDI Labelling: Apply compliant UDI carriers in both Human Readable Interpretation (HRI) and Automatic Identification and Data Capture (AIDC) formats on device labels and applicable packaging levels in accordance with Swiss regulatory requirements.
• Economic Operator Registration: Ensure manufacturers, Swiss Authorized Representatives, importers, and other applicable economic operators complete registration with Swissmedic and maintain current registration information.
• swissdamed Registration: Register applicable devices within the swissdamed UDI Devices module and maintain accurate device records throughout the product lifecycle.
• Lifecycle Data Management: Maintain consistency between swissdamed, technical documentation, declarations of conformity, product labelling, and internal source systems whenever regulatory or product changes occur.
• Post-Market Surveillance: Use UDI information to support vigilance reporting, field safety corrective actions (FSCAs), recalls, and other post-market surveillance activities required under Swiss regulations.

Key Compliance Milestones

Switzerland is implementing swissdamed through a phased approach, allowing manufacturers time to prepare for mandatory device registration while progressively expanding the national regulatory database.

Milestone	Timeline
Actors module available	August 2024
UDI Devices module available for voluntary registration	August 2025
Mandatory UDI device registration begins	1 July 2026
Transition period for existing devices ends	31 December 2026

Manufacturers should use this transition period to establish governance processes, prepare complete device records, and ensure regulatory data is synchronized across enterprise systems, technical documentation, and swissdamed before mandatory registration takes effect.

Strategic Value Beyond Compliance

Switzerland’s UDI framework should be viewed as an ongoing regulatory capability rather than a one-time registration exercise. As swissdamed becomes the central platform for Swiss medical device registration, maintaining accurate and governed product data will be essential for sustaining compliance throughout the device lifecycle.

A disciplined approach to data governance enables manufacturers to manage product changes more efficiently, maintain consistency across Swiss and EU regulatory submissions, reduce compliance risk, and support long-term market access. For organizations operating across multiple jurisdictions, establishing a trusted source of regulatory product data also simplifies the management of evolving global UDI requirements.
