eIDAS Trusted Service Providers
All EU Member States have a obligation to create, maintain and publish lists of "Trusted Service Providers (TSPs") and the qualified services provided by them.
Pursuant to Regulation (EC) No 910/2014 (eIDAS Regulation), the "Trusted Service Providers List" has a constitutive effect. This means a Service Provider is only qualified if they appear on the list.
Article 22 of the eIDAS Regulation requires Member States to establish, maintain, and publish these lists, including information about the service providers they are responsible for. The lists will also include information about the qualified services provided by them.
EU Member States may add services other than those qualified to the trusted lists on a voluntary basis at the national level, provided it is clearly indicated that they are not qualified under Regulation (EU) No 910/2014.
