EU eIDAS Regulation Attribute Attestations

Electronic attestations of attributes are eIDAS trust-service objects that let a user prove specific attributes, such as age, address, qualifications, mandates, permits, or company data, without turning every attribute proof into electronic identification.

This FAQ explains the difference between EAA, QEAA, and public-sector authentic-source attestations, plus the wallet, issuer, legal-effect, revocation, and relying-party checks that matter.

Overview

Under the amended eIDAS Regulation, an is an electronic attestation that allows attributes of a natural person, legal person, or object to be authenticated. The regulation gives special treatment to qualified electronic attestations of attributes and to attestations issued by, or on behalf of, a public sector body responsible for an . A relying party should check the attestation category, issuer authority, wallet presentation, validity status, and whether the requested attributes are necessary for the service.

Question 1

What is an electronic attestation of attributes under eIDAS?

An is a regulated way to prove facts about a natural person, legal person, or object through the eIDAS trust-service framework. eIDAS covers electronic attestation of attributes alongside signatures, seals, timestamps, electronic documents, registered delivery, website authentication, archiving, and electronic ledgers.

The attestation type controls the legal and validation checks. A non-qualified EAA can still have legal effect and evidentiary value, but a (QEAA) must meet Annex V requirements and be issued by a qualified trust service provider. A separate category covers attestations issued by, or on behalf of, a public sector body responsible for an ; those must meet Annex VII and the additional Article 45f requirements.

Commission Implementing Regulation (EU) 2025/1569 adds the operational rules for QEAAs and public-sector authentic-source attestations. Its issuance and revocation provisions have applied since 19 August 2025. Articles 6 to 9, which cover the public-sector provider list, attribute and scheme catalogues, and authentic-source verification mechanisms, apply from 19 August 2026. Commission Implementing Regulation (EU) 2026/1735 enters into force on 11 August 2026 and updates the applicable standards and technical specifications; its Article 1(3), which adds specifications for Article 9 verification mechanisms, applies from 1 January 2027.

  • Treat EAA as attribute proof, not automatically as electronic identification.
  • Classify the attestation as non-qualified EAA, QEAA, or public-sector authentic-source EAA before relying on it.
  • For a QEAA, verify that the attestation identifies the qualified trust service provider, the subject, the attested attributes and their scope, validity period, unique attestation identity code, qualified signature or seal, supporting certificate location, and validity-status service.
  • For a public-sector authentic-source EAA, verify the issuing public body, the authentic-source basis, the subject, the attested attributes, validity period, identity code, qualified signature or seal, supporting certificate, and status-check location.

Does eIDAS give electronic attestations of attributes legal and evidentiary effect?

Yes. eIDAS says an cannot be denied legal effect or admissibility as evidence only because it is electronic or because it is not qualified. It gives stronger treatment to QEAAs and public-sector authentic-source attestations: they have the same legal effect as lawfully issued paper attestations.

Question 2

Who can issue QEAAs and authentic-source attestations?

A QEAA is issued by a qualified trust service provider and must be able to show, in machine-processable form, that it is a . eIDAS also requires Member States to make measures available so qualified trust service providers can verify certain public-sector attributes electronically, at the user's request, against authentic sources or recognised intermediaries. Articles 6 to 9 of Commission Implementing Regulation (EU) 2025/1569 apply from 19 August 2026, while the specifications added to Article 9 by Commission Implementing Regulation (EU) 2026/1735 apply from 1 January 2027; availability before the relevant date can still depend on the Member State and .

A public-sector authentic-source attestation is different: it is issued by, or on behalf of, a public sector body responsible for the . The Member State must ensure those bodies meet a reliability and trustworthiness level equivalent to qualified trust service providers, notify them to the Commission, and make the public list available through a secure signed or sealed channel.

  • For QEAAs, check the qualified trust service provider identity and whether the service has qualified status for the relevant attestation service.
  • For public-sector authentic-source attestations, check whether the public body is responsible for the or designated to act on its behalf.
  • For attributes such as address, age, nationality or citizenship, educational and professional qualifications, mandates, permits, licences, and company data, check whether the attribute relies on a public-sector and whether electronic verification is available.
  • Do not accept issuer branding alone as proof of authority; check the attestation category, certificate, signature or seal, status information, and relevant trusted-list or registry information.

Question 3

How should wallets and relying parties use attribute attestations?

For wallet use, eIDAS requires providers of electronic attestations of attributes to let EUDI Wallet users request, obtain, store, and manage attestations regardless of the Member State where the wallet is provided. Providers of QEAAs and public-sector authentic-source attestations must provide an interface with EUDI Wallets.

Cryptographic verification alone does not complete a relying-party check. The EUDI Wallet Architecture and Reference Framework describes an ecosystem in which wallets let users request attestations from trusted issuers, store them, and present them to relying parties with user control, selective disclosure, relying-party authentication, issuer authorisation checks, and revocation/status checks.

  • Authenticate the relying party before the wallet presents attributes, and show the user whether the relying party is registered to receive the requested attributes.
  • Request only attributes needed for the service, because selective disclosure and user approval are core wallet controls.
  • Verify the issuer is authorised to issue the relevant attestation type; where available, inspect the issuer registration certificate or query the relevant registry.
  • Check whether the attestation or its signing certificate has been revoked, because revoked QEAAs and public-sector authentic-source attestations lose validity from revocation and status must not revert.
  • Keep the relying-party purpose, requested attributes, user approval, issuer authority check, certificate and status-check result, attestation validity period, and revocation outcome together as evidence of the relying decision.

Can an eIDAS attribute attestation replace electronic identification for public online services?

Not by default. eIDAS says that where national law requires electronic identification and authentication to access an online public-sector service, person identification data in an does not substitute electronic identification unless the Member State specifically allows it. If that allowance exists, QEAAs from other Member States must also be accepted.

What should a relying party check before accepting an attribute attestation from an EUDI Wallet?

A relying party should verify the wallet presentation, issuer identity and authorisation, attestation category, attested attribute and scope, subject binding or pseudonym indication, validity period, signature or seal, supporting certificate, status-check location, and revocation status. It should also check that the requested attributes match its registered purpose and are limited to what the service needs.
