Unique Identification Number (CHRN – Swiss Single Registration Number)

On 3 March 2022 the Swissmedic updated the guidance on the unique Swiss Single Registration Number for medical devices.

The Swiss Single Registration Number (CHRN) is a unique identification number that Swissmedic assigns to Swiss manufacturers, authorized representatives and importers upon request. The CHRN is used to unambiguously identify a manufacturer, authorized 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, authorized representatives and importers domiciled in Switzerland to register once with Swissmedic.
