Norway participates in the EU eIDAS framework through the EEA Agreement, with well-known qualified trust service providers such as Buypass and Commfides.
Supervisory authority
Qualified trust services in Norway are overseen by Nkom (Norwegian Communications Authority), which maintains the national trusted list referenced by the EU List of Trusted Lists.
Notable qualified trust service providers
- Buypass
- Commfides
This is not an exhaustive list — the authoritative, always-current set of qualified providers is Norway's national trusted list, indexed by the EU LOTL. Sealium validates against the live list, so new providers are recognised automatically.
How to validate Norway signatures
Send the document to the Sealium API and it resolves Norway'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.

Norway's qualified providers are published on its national trusted list, which is indexed by the EU List of Trusted Lists.
Who publishes Norway's trusted list?
Norway's trusted list is published under the supervision of Nkom (Norwegian Communications Authority) and referenced by the EU List of Trusted Lists.
How do I validate a Norway electronic signature?
Check the signature against Norway's national trusted list (via the EU LOTL): verify integrity, build the certificate chain, check revocation and any timestamp, and read the eIDAS level. Sealium does all of this in one /v1/validate API call and returns a structured report.
