What Is a EUDAMED SRN, and Why You Need One First
8 September 2026
Before a single device can be registered in EUDAMED, your company needs an SRN — a Single Registration Number. It’s easy to gloss over as a formality, but nothing else in EUDAMED works without it.
What it is
The SRN is EUDAMED’s identifier for your company as a registered economic operator — manufacturer, authorised representative, importer, or system/procedure pack producer. It follows a fixed format: two letters for the country, then a role code, then a number — for example GR-MF-000000001 for a manufacturer (MF) registered in Greece (GR).
Where it’s used
Every device, certificate, and registration you submit is tied to your SRN. It’s how EUDAMED confirms you’re allowed to register or update a given record in the first place — without it, there’s no account for a device registration to belong to.
It comes from actor registration, not device registration
Getting an SRN happens through EUDAMED’s Actor Registration module, a separate step from registering your devices — your company registers itself as an economic operator first, and only once that’s confirmed does device-level registration become possible. This is a one-time step per company, not something repeated per device or per submission.
A common mixup
If you’re an EU-based manufacturer using an Authorised Representative, or referencing an OEM/original manufacturer on your devices, those parties need their own SRNs too — you can’t substitute your own. Getting these mismatched is a common source of confusion the first time a company works through this.
Once you have your SRN confirmed, everything downstream — Basic UDI-DI, UDI-DI, certificates — references it automatically. It’s the one prerequisite worth getting right before anything else.
