Note

ETSI technical specification defining the format and semantics of the trusted lists published by Member States (version 2.4.1).

Summary

Purpose

Technical specification ETSI TS 119 612 (version 2.4.1, August 2025) defines the format of trusted lists, the lists published by Member States that indicate the status of qualified trust service providers and qualified trust services ETSI TS 119 612 V2.4.1, § 1 Scope ETSI TS 119 612 V2.4.1, History. Its scope begins as follows:

It defines the format and semantics of a trusted list, the access mechanisms, guidance for locating and authenticating it, and requirements for the relying parties that use it ETSI TS 119 612 V2.4.1, § 1 Scope.

Who it applies to

• Member States, which establish, publish and maintain trusted lists compliant with the specifications of Annex I to Implementing Decision 2015/1505, and sign or seal them Art. 1 Art. 3.
• Relying parties that use these lists, for which the specification sets requirements ETSI TS 119 612 V2.4.1, § 1 Scope.

Key points

• Structure: information on the scheme (operator, name, policy, next update…), then the list of providers, then, for each, the list of its services ETSI TS 119 612 V2.4.1, § 5.3 Scheme information ETSI TS 119 612 V2.4.1, § 5.4 TSP information ETSI TS 119 612 V2.4.1, § 5.5 Service information.
• Service types: qualified and non-qualified types of Regulation 910/2014, and types defined at national level ETSI TS 119 612 V2.4.1, § 5.5.1 Service type identifier.
• Service digital identity: the data that allows the service to be recognised, for example by its certificate ETSI TS 119 612 V2.4.1, § 5.5.3 Service digital identity.
• Status: for a qualified service of a Member State, the status is granted or withdrawn ETSI TS 119 612 V2.4.1, § 5.5.4 Service current status.
• Implementation: XML syntax, schema and registered URIs (Annexes B, C and D) ETSI TS 119 612 V2.4.1, Annex B (normative): Implementation in XML ETSI TS 119 612 V2.4.1, Annex C (normative): XML schema ETSI TS 119 612 V2.4.1, Annex D (normative): Registered Uniform Resource Identifiers.

What the acts apply, and how

• Implementing Decision 2015/1505: its Annex I bases the specifications of trusted lists on TS 119 612 version 2.4.1; where no specific requirement is set, clauses 5 and 6 of the specification apply in their entirety Annex I. The Decision prevails in case of discrepancy:

The annex then specifies, field by field, many clauses of the specification (scheme name, information, policy, certificates to be notified…) Annex I. The reference to version 2.4.1 comes from Implementing Decision 2025/2164, which amends Annex I; the original Decision used version 2.1.1 Art. 1 amending Implementing Decision (EU) 2015/1505 as regards the version of the standard on which the common template for the trusted lists is based. This amendment applies from 29 April 2026 Art. 2. According to its recitals, version 2.4.1 makes it possible to indicate the status of the new qualified trust services introduced by Regulation 2024/1183 amending Implementing Decision (EU) 2015/1505 as regards the version of the standard on which the common template for the trusted lists is based.

• Implementing Regulation 2025/2162: its Annex II names TS 119 612 version 2.4.1 before the list of standards per service, unlike the other standards in the list, which are cited without a version Annex II; conformity assessment schemes include at least these standards, as applicable Art. 6(3). Its Annex III requires the conformity assessment report to list the digital identities of the services according to paragraph 5.5.3 of version 2.4.1 Annex III.
• Implementing Regulations 2025/1942, 2025/1945 and 2025/1946: their adaptations of the validation and preservation standards (TS 119 172-4 version 1.1.1, and TS 119 511 version 1.1.1 for 2025/1946) replace reference [2] with TS 119 612 version 2.3.1 Annex List of reference standards and specifications for the validation of qualified electronic signatures and of qualified electronic seals List of reference standards and specifications referred to in Article 2.
