Denmark is a full participant in the EU eIDAS framework, where electronic signing is widespread through the national MitID infrastructure and qualified providers.
Supervisory authority
Qualified trust services in Denmark are overseen by Danish Agency for Digital Government, which maintains the national trusted list referenced by the EU List of Trusted Lists.
Notable qualified trust service providers
- Den Danske Stat
- Penneo A/S
- IN Groupe Denmark A/S
This is not an exhaustive list — the authoritative, always-current set of qualified providers is Denmark's national trusted list, indexed by the EU LOTL. Sealium validates against the live list, so new providers are recognised automatically.
How to validate Denmark signatures
Send the document to the Sealium API and it resolves Denmark's trusted list automatically, returning each signature's eIDAS level, signer, certificate chain, revocation status and timestamps as a structured report — no per-country configuration required.

Denmark's qualified providers are published on its national trusted list, which is indexed by the EU List of Trusted Lists.

Denmark's trusted list is published under the supervision of Danish Agency for Digital Government and referenced by the EU List of Trusted Lists.
How do I validate a Denmark electronic signature?
