3. Trusted Lists and Other Nationally Maintained Information

EU Member States and other European nations generally maintain lists of CAs and other TSPs in one or more nationally maintained registers.

EU Member States trusted list as defined in Regulation (EU) No 910/2014 include information related to the qualified trust service providers which are supervised by the competent Member State, together with information related to the qualified trust services provided by them, in accordance with the relevant provisions laid down in the Regulation.

Trusted lists are essential elements in building trust among electronic market operators by allowing users to determine the qualified status and the status history of trust service providers and their services. Under eIDAS Regulation, national trusted lists have a constitutive effect. In other words, a provider/service will be qualified only if it appears in the trusted lists. Consequently, the users (citizens, businesses or public administrations) will benefit from the legal effect associated with a given qualified trust service only if the latter is listed (as qualified) in the trusted lists.

The trusted lists of Member States include, as a minimum, information specified in Articles 1 and 2 of Commission Implementing Decision (EU) 2015/1505 profiling technical specifications defined in ETSI TS 119 612 v2.1.1.

Member States may include in the trusted lists information on non-qualified trust service providers and on other nationally defined trust services.

To allow access to the trusted lists of all Member States in an easy and trustworthy manner, the European Commission publishes a central list with links to the locations where the trusted lists are published as notified by Member States to the EC. This central list, called the List Of Trusted Lists (LOTL), is available as a signed or sealed XML machine-processable form (hereafter the LOTL) at the following URL: https://ec.europa.eu/information_society/policy/esignature/trusted-list/tl-mp.xml

Also some Trusted Lists viewers are available as follows:

4. Qualified Certificates

For EU countries the information on CAs issuing qualified certificates are held in Trusted Lists (see 3 above).

5. Conformity Assessment Bodies

Conformity assessment bodies are accredited by national accreditation bodies. The relevant national accreditation body can be contacted to determine the status of a conformity assessment body (i.e. whether the conformity assessment body is accredited to perform ETSI audits by the national accreditation body). National accreditation bodies can be found on the European Co-operation for Accreditation web site and/or the International Accreditation Forum web site.

Informative list of conformity assessment bodies (CABs) accredited against the requirements of the eIDAS Regulation: The information included in the list comes from the National Accreditation Bodies (NAB) who have notified the European Commission.
