Economic operators must register with Swissmedic before placing a device on the Swiss market (pursuant to Art. 55 MedDO and Art. 48 IvDO).
Applications for registration and for changing the CHRN, as well as notifications of mandates, are submitted in the Actors module of swissdamed.
CHRN (Swiss Single Registration Number)
Based on the Medical Devices Ordinance (MedDO; SR 812.213) and the Ordinance on In Vitro Diagnostic Medical Devices (IvDO; SR 812.219), Swissmedic assigns, upon request, a Swiss Single Registration Number (CHRN) to the economic operator concerned, thereby allowing the operator to be identified unambiguously. Evidence of domicile in Switzerland (i.e. extract from the commercial register or certificate of residence) must be attached to the application.
The CHRN consists of the abbreviation “CHRN”, followed by the abbreviation for the requested role and an eight-digit number (e.g. CHRN-MF-23456789), as explained in the figure below:
