EUDAMED registration for medical devices and IVDs

Register the legal entity first. Then make every product record agree with the evidence behind it.

EUDAMED is no longer a voluntary preview. The practical challenge is to connect the actor, authorised representative, identifiers, device data and certificates without creating contradictions that surface during validation or market surveillance.

2026

The current position

Four modules are mandatory. Two are still waiting.

Commission Decision (EU) 2025/2371 confirmed that four modules were functional. The six-month transition ended on 28 May 2026, turning them from voluntary systems into the required route for the functions they cover.

01 Mandatory

Actor registration

Economic-operator identity, competent-authority validation and SRN or Actor ID.

Industry-facing
02 Mandatory

UDI and device registration

Basic UDI-DI, UDI-DI, EMDN and the regulatory data describing each device.

Industry-facing
03 Mandatory

Notified Bodies and certificates

Notified Body decisions, certificates and related certificate information.

Notified Body-facing
04 Mandatory

Market surveillance

Coordination and exchange of surveillance information between authorities.

Authority-facing
05

Vigilance and post-market surveillance

In development
06

Clinical investigations and performance studies

Under analysis

Interactive actor route

The correct registration path begins with the legal role

Select a role to see who validates the request, which identifier is issued and where the critical dependency sits.

Direct actor route

Register the manufacturer before registering its devices

The actor request goes to the competent authority responsible for the manufacturer’s registered place of business. After validation, EUDAMED issues the SRN used in subsequent regulatory transactions.

Identifier

Single Registration Number

Validator

Responsible competent authority

Dependency

Exact legal-entity data and signed information-security declaration

Next move

Approve user access and prepare device master data

The controlled sequence

Do not begin with data entry. Begin with ownership.

A clean submission depends on decisions made before anyone opens the EUDAMED form.

  1. 01
    Governance

    Name the Local Actor Administrator

    Give one accountable function authority to control the actor record, approve users and coordinate regulatory data owners.

  2. 02
    Identity

    Freeze the legal-entity record

    Align legal name, address, registration identifiers and economic-operator role with contracts, certificates and regulatory documentation.

  3. 03
    Actor request

    Submit the evidence and declarations

    Complete the actor request, upload the signed information-security declaration and include the representative mandate summary where required.

  4. 04
    Validation

    Resolve authority questions and receive the SRN

    The competent authority verifies the request. EUDAMED generates the identifier only after approval.

  5. 05
    Access

    Approve users by function, not convenience

    Every person acting for the organisation requests access. Grant the minimum role needed and remove access promptly when responsibilities change.

  6. 06
    Device record

    Publish controlled master data

    Build the Basic UDI-DI and UDI-DI records from approved sources, verify links and retain evidence of review before submission.

The identifier architecture

One product can carry several identifiers without becoming several products

The most common conceptual error is to treat the SRN, Basic UDI-DI, UDI-DI and UDI-PI as competing labels. Each identifies a different layer.

WHO Actor or organisation

SRN

Identifies the registered economic operator, not a device.

FAMILY Regulatory device group

Basic UDI-DI

Connects devices that share defined purpose, class and essential design characteristics.

MODEL Specific trade item

UDI-DI

Identifies a device model, version or packaging level according to the UDI rules.

PRODUCTION Unit or batch information

UDI-PI

Carries lot, serial, software-version, manufacture or expiry information as applicable.

Important distinction

EUDAMED device registration is performed at the UDI-DI or applicable device-identifier level. It does not create a separate database record for each serial number, lot or other individual UDI-PI.

Submission readiness

Make the database the output of controlled records

Each EUDAMED field should have an owner and a source. If the public record, Declaration of Conformity, certificate, label and technical documentation describe the device differently, the database has exposed a governance problem rather than created one.

01

Identity data

Legal manufacturer, authorised representative, importer links and validated actor identifiers.

02

UDI structure

Issuing entity, Basic UDI-DI, UDI-DI, packaging hierarchy and applicable production identifiers.

03

Regulatory attributes

Device class, applicable legislation, intended purpose, model, trade name and special characteristics.

04

Nomenclature

Current EMDN code selected at the right level and supported by the device’s purpose and technology.

05

Conformity links

Notified Body and certificate references where applicable, aligned with the covered device scope.

06

Lifecycle status

Market status, dates, changes and discontinuation handled through documented regulatory change control.

Transition timeline

The switch became legal in stages, but the data work should not

Whether a record was due immediately or within a transition depends on what was placed on the market and when.

Functionality notice

The six-month clock began

The Commission published the notice confirming that the first four modules were functional.

Mandatory use

New actor and device obligations moved into EUDAMED

A device first placed on the market from this date must be registered before the first unit is placed on the market.

Device transition end

Continuing qualifying device records became due

The six-month period ended for relevant Regulation and legacy devices already on the market and still being placed on the market.

Certificate transition end

Earlier MDR and IVDR certificate records become due

Notified Bodies complete the 18-month transition for certificates issued before mandatory use of the certificate module.

Not registered in UDI/Device

Custom-made devices

The device itself is outside ordinary UDI/Device registration, although its manufacturer may need actor access for other obligations.

Not registered in UDI/Device

Investigational and performance-study devices

They do not follow the commercial UDI/Device registration route. Study processes remain subject to their own legal and transitional channels.

Conditional transition

Devices no longer placed on the market

A device that ceased being placed on the market before mandatory use may remain outside registration unless a later post-market or vigilance action requires a record.

After registration

A valid submission can become inaccurate the next morning

Legal names change. Representatives change. Certificates are suspended or replaced. Product configurations and market status evolve. EUDAMED maintenance therefore belongs inside regulatory change control rather than inside one administrator’s inbox.

The control objective

One approved change should update every affected record, label, declaration, certificate link and EUDAMED field through the same traceable workflow.

01

Detect

Regulatory, corporate, product or certificate change begins.

02

Assess

Owners identify affected actor and device records.

03

Approve

Source evidence and revised data receive controlled review.

04

Reconcile

EUDAMED and internal records are checked for agreement.

Failure patterns

Most registration defects begin outside EUDAMED

The database usually reveals identity, classification or master-data decisions that were never resolved properly.

01

A brand is entered as the manufacturer

The legal entity on the actor record does not match the entity carrying MDR or IVDR manufacturer responsibility.

Resolve the legal role before the record
02

The SRN is treated as a product identifier

The economic-operator identifier is confused with the Basic UDI-DI or UDI-DI structure.

Map each identifier to its layer
03

Certificates and device scope disagree

Models, classes or Basic UDI-DIs in the device record do not align with the Notified Body certificate.

Reconcile before publication
04

EMDN selection is delegated without context

A code is chosen by keyword rather than intended purpose, technology and regulatory characteristics.

Document the nomenclature rationale
05

User access survives role changes

Former staff or suppliers retain unnecessary permissions while current owners cannot act.

Review access as a controlled record
06

The submission becomes the master file

Information is invented in the interface and no approved internal source can later explain it.

Publish from controlled source data

Practical questions

EUDAMED registration FAQ

Open the question that affects your actor request, UDI plan or transition review.

Which EUDAMED modules are mandatory now?+

Since 28 May 2026, the Actor Registration, UDI/Device Registration, Notified Bodies and Certificates, and Market Surveillance modules have been mandatory. The first three directly support industry registration and conformity workflows. The Market Surveillance module is primarily used by competent authorities and the European Commission. The Vigilance and Post-market Surveillance module and the Clinical Investigations and Performance Studies module are not yet mandatory.

Who must obtain a Single Registration Number?+

Manufacturers, authorised representatives and importers that fall within MDR Article 31 or IVDR Article 28 must register as actors. EUDAMED issues an SRN after the competent authority validates the request. A system or procedure pack producer receives an Actor ID rather than an SRN.

Must distributors register as EUDAMED actors?+

No. Distributors are not required to register in the EUDAMED Actor module. National registration obligations may still apply, and a distributor that assumes manufacturer obligations under MDR or IVDR Article 16 must assess its role separately.

How does a non-EU manufacturer register?+

A non-EU manufacturer needs an active EU authorised representative before submitting its actor request. The request includes information about the representative and a mandate summary. The authorised representative verifies the request before it proceeds to the responsible competent authority for validation.

What is the difference between Basic UDI-DI, UDI-DI and UDI-PI?+

The Basic UDI-DI is the main regulatory identifier for a group of devices sharing defined characteristics. The UDI-DI identifies a specific device model or trade item. The UDI-PI identifies production information such as a lot, serial number, software version or expiry date. EUDAMED device registration is performed at identifier level and does not create a separate device record for every individual UDI-PI.

What was the 28 November 2026 device deadline?+

The transition rules give qualifying Regulation and legacy devices that were already placed on the market before 28 May 2026 and continue to be placed on the market a six-month registration period ending on 28 November 2026. A device first placed on the market on or after 28 May 2026 must be registered before its first unit is placed on the market.

Are custom-made and investigational devices entered in the UDI/Device module?+

No. Custom-made devices, investigational devices and devices for performance studies are excluded from ordinary UDI/Device registration. A custom-made device manufacturer may nevertheless need actor registration when another EUDAMED obligation requires access.

What happens while two EUDAMED modules remain unfinished?+

Economic operators should use the mandatory EUDAMED modules for the functions now covered by them. Vigilance, post-market surveillance, clinical-investigation and performance-study processes continue through the applicable EU transitional and national channels until the corresponding modules become mandatory.
