UdiWatchNotes
UDI-DI, SRN, and what EUDAMED actually publishes.
Written for the searches people run before they trust a code on a label. Each note says what the public register contains, and what it does not.
- What is a UDI-DI?
30 September 2026 · A UDI-DI is the device identifier in the EU Unique Device Identification system. It names the device model in EUDAMED, not one physical unit.
- What is an SRN in EUDAMED?
30 September 2026 · An SRN is the Single Registration Number of an economic operator in EUDAMED. Manufacturer SRNs look like AT-MF-000000252.
- Basic UDI-DI vs UDI-DI
30 September 2026 · The UDI-DI identifies one device model. The basic UDI-DI groups models for one intended purpose, and EUDAMED hangs certificates on that group.
- EUDAMED: “no longer on the market”
30 September 2026 · EUDAMED status is on the market, no longer on the market, or not intended for the EU. A change is a new UDI-DI version, not a silent edit.
- EUDAMED certificate expiry dates
30 September 2026 · Public EUDAMED certificate expiry hangs on the basic UDI-DI, not the label UDI-DI. If the date is absent, the public response had none.
- How to search a device in public EUDAMED
30 September 2026 · Search the public EUDAMED register by UDI-DI, trade name, catalogue reference, or manufacturer SRN. Exact codes and fuzzy names do not work the same way.
- How to monitor EUDAMED for changes
30 September 2026 · Monitor an EUDAMED UDI-DI or manufacturer SRN by storing a public snapshot and comparing the next read. The first read is a baseline, not an alert.
- MF, AR, IM and PR in an EUDAMED SRN
30 September 2026 · An EUDAMED SRN encodes country, role, and digits. MF is the manufacturer, AR the authorised representative, IM the importer, and PR the pack producer.
- MDR or IVDR on an EUDAMED device
30 September 2026 · The legislation field on a public EUDAMED device is MDR or IVDR. It is the regulation the manufacturer registered, not a second market status.
- EUDAMED risk class: I to III, A to D
30 September 2026 · A public EUDAMED device shows the risk class the manufacturer registered. MDR uses I to III. IVDR uses A to D. The class is not a certificate.
- GS1, HIBC, and the UDI-DI on the label
30 September 2026 · A UDI-DI is issued by GS1, HIBCC, ICCBBA, or IFA. A 14-digit number is often a GTIN. The public page shows that code, not a new one.
- EUDAMED actor registration from May 2026
30 September 2026 · Actor registration in EUDAMED became obligatory on 28 May 2026 for manufacturers, authorised representatives, importers, and pack producers.
- Catalogue number versus UDI-DI
30 September 2026 · A catalogue or reference number is the manufacturer’s own code. A UDI-DI is the device identifier in EUDAMED. They can share a label and still differ.
UdiWatch is not an official European Commission service. The register itself is EUDAMED.
