Overview

The eIDAS requirements page is for teams that need to know which electronic identity or trust-service obligations apply before they design a signing, sealing, timestamping, certificate, wallet, or validation workflow. The main distinction is role-based: a qualified trust service provider has regulatory duties and supervision requirements, while a customer, relying party, or verifier must usually prove that it used the right qualified status, certificate status, wallet registration, and validation evidence for the transaction.

Section 1

Start with the eIDAS role and service type

eIDAS covers electronic identification, trust services, electronic signatures, electronic seals, electronic time stamps, electronic registered delivery, website authentication certificates, electronic attestations of attributes, electronic archiving, electronic ledgers, and the European Digital Identity Wallet. A requirements review should start by naming the service and the actor: trust service provider, qualified trust service provider, wallet provider, relying party, issuer, signatory, seal creator, browser provider, or customer relying on a certificate or validation result.

Do not label a workflow as qualified only because it is electronic or cryptographic. Qualified status depends on the eIDAS legal category, the provider's status, the certificate or device requirements, and trusted-list evidence.

  • Classify the workflow as electronic identification, signature, seal, time stamp, registered delivery, website authentication, attestation of attributes, archiving, ledger, or wallet use.
  • Record whether the provider is qualified, non-qualified, or only a relying party using a third-party trust service.
  • For qualified services, verify that the provider and the specific service appear with the right status on the relevant trusted list.
  • For signatures and seals, separate legal effect from format: advanced, qualified-certificate-backed, and qualified signatures or seals are not interchangeable.
  • For EUDI Wallet use, record whether the organisation is asking wallet users for data, issuing attestations, providing wallet infrastructure, or only validating a presented credential.
Section 2

Qualified trust service provider duties

A qualified trust service provider must be treated as a regulated provider, not only as a technology supplier. Before starting a qualified trust service, the provider must notify the supervisory body and submit a conformity assessment report. Qualified providers are audited at their own expense at least every 24 months by a conformity assessment body, and they must submit the resulting report to the supervisory body within three working days of receipt.

The operational requirements include identity or attribute verification before issuing qualified certificates or qualified electronic attestations of attributes, clear terms and limitations before contracting, trustworthy systems, reliable stored data, risk-management policies, security-breach and disruption notification, measures against forgery or misappropriation, accessible records for evidence and continuity, termination planning, and certificate databases where qualified certificates are issued.

  • Keep the supervisory notification, conformity assessment report, audit schedule, audit result, and any supervisory correspondence together.
  • Maintain identity and attribute verification evidence for qualified certificates and qualified electronic attestations of attributes.
  • Keep customer terms, service limitations, certificate policies, practice statements, liability insurance or financial-resource evidence, and change notices.
  • For significant security breaches or disruptions affecting the trust service or personal data, retain the 24-hour notification analysis, recipients, timestamps, and remediation evidence.
  • For revocation, keep request time, publication time, certificate or attestation status, validity-response logs, and evidence that the status was available to relying parties.
Section 3

Electronic signatures, seals, time stamps, and validation evidence

eIDAS gives electronic signatures and electronic seals legal-effect rules, but qualified status still requires specific supporting evidence. A qualified electronic signature has the equivalent legal effect of a handwritten signature; a qualified electronic seal carries presumptions about data integrity and origin; and a qualified electronic time stamp carries presumptions about the accuracy of date and time and integrity of the bound data.

For validation, the evidence record should prove the certificate status at signing, the provider's qualified status, the integrity of the signed or sealed data, the signatory or seal-creator information made available to the relying party, the qualified signature or seal creation device where required, and any pseudonym indication. A validation result alone is weak if it cannot be tied back to the trusted list, certificate status, signed object, and time of validation.

  • For qualified electronic signatures, retain the signed object, validation report, qualified certificate status at signing, QTSP identity, QSCD evidence, integrity check, and signatory data supplied to the relying party.
  • For qualified electronic seals, retain the sealed object, creator identity evidence, certificate status, integrity check, and qualified validation or preservation result where used.
  • For qualified electronic time stamps, retain the timestamp token, bound data hash or object reference, UTC-linked time-source evidence, and QTSP signature or seal evidence.
  • For public-sector online services, record which advanced or qualified signature or seal formats or methods were accepted for cross-border use.
  • For long-term reliance, retain preservation-service records or renewal evidence so the signature, seal, or timestamp remains verifiable after certificate or algorithm changes.
Section 4

EUDI Wallet relying-party requirements

A relying party that intends to rely on European Digital Identity Wallets for public or private digital services must register in the Member State where it is established. The registration must include information needed to authenticate to wallets, contact details, and the intended wallet use, including the data the relying party will request from users.

After registration, the relying party must not ask wallet users for data beyond the registered purpose, must identify itself to the user, must authenticate and validate person identification data and electronic attestations of attributes requested from wallets, must inform the Member State without delay about registration-information changes, and must not refuse pseudonyms where user identification is not required by Union or national law. Intermediaries acting on behalf of relying parties are treated as relying parties and must not store data about the content of the transaction.

  • Keep the Member State registration record, relying-party identity data, contact details, intended-use statement, and list of wallet data requested from users.
  • Show that user-facing wallet requests match the registered data categories and purpose.
  • Retain wallet authentication, relying-party identification, PID validation, EAA validation, and pseudonym handling evidence.
  • Record changes to relying-party information and the date the Member State was informed.
  • For intermediaries, retain contracts and technical logs proving they act as relying parties and do not store transaction-content data.
Section 5

Trusted lists and qualification checks

Trusted lists are central evidence under eIDAS. Each Member State must establish, maintain, and publish trusted lists containing information on qualified trust service providers and their qualified trust services. A qualified trust service provider may begin providing a qualified trust service only after qualified status has been indicated in the trusted list.

A relying party should therefore preserve the trusted-list result used for each material decision: whether a provider was qualified, whether the specific service was qualified, whether a certificate or attestation was valid or revoked, and whether the trusted-list data was current when checked.

  • Record the trusted-list location, scheme territory, provider name, service name, service type, current status, status start time, and validation timestamp.
  • For EU trust mark claims, verify that the provider links from its website to the relevant trusted list for the qualified service.
  • For certificate validation, retain revocation and validity-status responses beyond the certificate validity period where the provider makes them available.
  • For wallet ecosystems, distinguish eIDAS trusted lists for qualified trust services from wallet, PID, QEAA, or service-provider certification and trust-list checks.
  • Treat trusted-list failures, missing service status, expired or revoked certificates, and mismatched service type identifiers as stop-and-escalate conditions.
Section 6

Evidence checklist for eIDAS requirements

The minimum useful eIDAS evidence package is a role-and-service classification, a source citation, status proof, and transaction-level validation evidence. It should be possible for a reviewer to reconstruct why a signature, seal, timestamp, wallet request, certificate, attestation, or provider status was accepted at the time of use.

The checklist below is intentionally evidence-first. It avoids broad compliance claims and focuses on records that prove the actual eIDAS requirement that applied.

What is the first requirement to check under eIDAS?

First classify the actor and service: trust service provider, qualified trust service provider, relying party, wallet provider, issuer, signatory, seal creator, or customer relying on a validation result. Then verify whether the specific service is qualified and whether trusted-list or wallet-registration evidence is required.

What evidence proves a qualified electronic signature was valid under eIDAS?

Keep the signed object, the validation result, the qualified certificate status at signing, the QTSP and service status from the trusted list, evidence that the qualified signature creation device requirement was met, and proof that the signed data integrity was not compromised.

What must an EUDI Wallet relying party keep under eIDAS?

Keep the Member State registration record, relying-party identity and contact details, intended wallet use, requested data categories, user-facing request evidence, PID or EAA validation records, pseudonym handling rationale, and updates sent to the Member State.

  • Role record: actor, service type, jurisdiction, provider status, relying-party status, wallet role, and whether the activity is qualified or non-qualified.
  • Source record: eIDAS article or official guidance used, source URL with retrieval date, and the specific requirement being applied.
  • Provider record: QTSP status, supervisory notification or approval where relevant, conformity assessment reports, audit cadence, service terms, termination plan, and breach-notification records.
  • Transaction record: signed or sealed object, timestamp token, certificate chain, revocation status, trusted-list proof, validation result, data requested from a wallet, and user-facing request screen or API evidence.
  • Change record: provider changes, certificate revocations, wallet relying-party registration changes, trusted-list changes, security incidents, and product changes that alter the eIDAS role or service type.
