What is a Swiss Single Registration Number (CHRN)?

A Swiss Registration Number (CHRN) is a unique identification number issued by Swissmedic to economic operators: manufacturers, authorized representatives and importers.

The CHRN is Switzerland’s version of the EUDAMED Single Registration Number (SRN).

Why is a CHRN Needed?

A CHRN is required in place of the EUDAMED Single Registration Number (SRN) because the Mutual Recognition Agreement (MRA) between Europe and Switzerland lapsed for medical devices and IVDs. After 26 May 2021 (medical devices) and 26 May 2022 (IVDs), the free movement of devices between the two areas was no longer allowed. Further, the EU Commission removed Switzerland’s Competent Authority level access to EUDAMED.

Since Switzerland’s regulations reference EUDAMED throughout, it had to quickly address the gap. This included creating its own version of European SRNs – Swiss Single Registration Numbers.

Further, Swissmedic is developing its own EUDAMED-like registration database, called Swissdamed.

It will consist of two registration modules:

1. 1. Economic Operators 
   2. Medical Devices

It will launch in phases through 2023-2024.

Is a CHRN Mandatory or Voluntary?

A CHRN is mandatory for Swiss-based Manufacturers, Authorized Representatives and Importers. This is different from Europe, where the Single Registration Number (SRN) is voluntary until EUDAMED is fully functional. Full functionality is currently projected to be Q2 2024 and then followed by a six-month transition period for the Actor, Vigilance, Clinical Investigation & Performance Studies and Post-market Surveillance modules, after which its use will be mandatory. Another 18-month transition period is granted for the UDI/Device and Notified Body & Certificates modules.

A CHRN is required for economic operators of both MDR/IVDR CE marked devices and legacy devices CE marked to the old Directives.

Who Needs a CHRN?

The following criteria apply:

1. 1. Only four types of organizations require a CHRN: Manufacturers,  System/Procedure Pack Producers, Authorized Representatives and Importers.
   2. Only companies located in Switzerland require a CHRN. For example, a manufacturer located in Germany or Canada, does not need, and cannot get, a CHRN. This is different from Europe, which requires an SRN for all manufacturers, irrespective of where they are located. Instead, the foreign manufacturer’s Swiss Authorized Representative (AR) and Importer must obtain a CHRN.

NOTE: Even though a distributor is also an economic operator, they do not require a CHRN. This is the same as Europe’s Economic Operator registration requirements.

How Do I Obtain a CHRN?

Swiss Manufacturers, Authorized Representatives (AR) and Importers must submit an application to Swissmedic.

The steps are:

(1) Complete application: BW630_11_001 defi_FO_Antrag_Registrierung_CHRN

• • The language can be changed by clicking on the flag at the top left

(2) Email CHRN@swissmedic.ch and attach the following:

• • Completed application form – do not send a scanned or hard copy of the form or it will be rejected
  • Commercial registry (proof of operation in Switzerland)
  • Authorized Representatives only: Mandate form with the manufacturer and AR’s details

(3) Swissmedic will review the application, and barring any questions, send a letter confirming the CHRN by post

(4) Swissmedic will send the invoice after the CHRN has been processed

What is the Deadline to Obtain a CHRN?

Swiss Manufacturers, Authorized Representatives and Importers must obtain a CHRN within three months of placing their first product on the Swiss market.

That said, there is an exception of sorts. Foreign manufactures who placed devices onto the Swiss market before the MRA lapsed on 26 May 2021 (medical devices) or 26 May 2022 (IVDs), have a grace period to appoint a Swiss Authorized Representative. The deadlines are:

• • Class III/AIMD/Class IIb implantable – 31 December 2021
  • Class IIb non-implantable/IIa – 31 March 2022
  • Class I and System/Procedure Pack Producers – 31 July 2022
  • Class D IVDs – 31 December 2022
  • Class C, B IVDs – 31 March 2023
  • Class A IVDs – 31 July 2023

How Long Does it Take to Get a CHRN?

Swissmedic’s official timeframe to process CHRN requests is 30 days. However, they also state that “if the volume of applications is low, the processing time may be shorter”.

What is the Fee for a CHRN?

Swissmedic charges an hourly fee of CHF 200 to process CHRN requests. Swissmedic advised that most applications are processed in one hour, unless there are questions or findings made.

This amount will be invoiced after the CRHN application has been processed. Invoices will only be issued to an address in Switzerland. Companies can wait to receive the invoice by post, or can submit a request to receive invoices by e-mail.

How Long is the CHRN Valid?

CHRNs do not expire. However, Swissmedic must be notified of changes within one week.

The types of changes that must be notified include:

• • Details of the economic operator
  • Change to the Swiss Economic Operator’s Person Responsible for Regulatory Compliance (PRRC)
  • Contact details for the organization
  • Update to invoice address

Change notifications should be made to CHRN@swissmedic.ch and the following form attached: BW630_12_002defi_FO Notification of information changes

Note about the Mutual Recognition Agreement

A CHRN is required for as long as there is no MRA for medical devices between Switzerland and the EU. If the lapsed MRA is eventually resolved, then presumably manufacturers will either have their information rolled into EUDAMED by Swissmedic, or more likely, be required to re-register in EUDAMED and obtain an EU SRN.
