Unique identification no. in accordance with Art. 55 MedDO (CHRN – Swiss Single Registration Number)

The Swiss Single Registration Number (CHRN) is a unique identification number that Swissmedic assigns to Swiss manufacturers, authorised representatives and importers upon request. The CHRN is used to unambiguously identify a manufacturer, authorised representative or importer.

Until the MRA (Mutual Recognition Agreement) is updated, Swissmedic is unable to assign a European Single Registration Number (SRN) via EUDAMED for economic operators who are domiciled in Switzerland.

To mitigate the consequences of this loss of information and to continue to ensure market surveillance in Switzerland, it is necessary for manufacturers, authorised representatives and importers domiciled in Switzerland to register once with Swissmedic. After the successfull review of the information, Swissmedic will assign a Swiss Single Registration Number (CHRN) to the applicant.

Economic operators must register within three months of placing their first product on the Swiss market. This timeframe is intended to avoid delays in bringing compliant products onto the market and to prevent supply bottlenecks in Switzerland.

This rule also applies to persons who assemble systems and treatment units in accordance with Art. 11 MedDO. These persons are considered to be economic operators under Art. 47 para. 4 let. e TPA and must report to Swissmedic with their name and address within three months of placing systems or treatment units onto the market for the first time.

Once an economic operator has registered, it does not have to do so again when placing further products on the market.

Service Agreement

The service agreement describes the services that the Swiss Therapeutic Products Agency provides in terms of issuing a Swiss Single Registration Number (CHRN) in accordance with MedDO Art. 55. It also describes the entitlements and obligations of the persons who make use of this service.

With each order, the service recipient explicitly agrees to the conditions of this service agreement.

Single Registration Number (SRN)

According to the EU Commission publication, Swissmedic will only be able to assign SRNs once the MRA (Mutual Recognition Agreement) has been updated. Switzerland is still seeking to precisely establish with the EU the conditions that will apply to market access and cooperation in the medical devices field.

As soon as Swissmedic obtains access to EUDAMED, this will be published on our website.
