The Register micro service gives register information to Apps.

  • ER - Enhetsregisteret - Information about organisations in Norway
  • DSF - Det Sentrale Folkeregisteret - Information about citizens in Norway.

ER - Enhetsregisteret

ER registeret can be used to prefill information, retrieve information based on user input or for validation of input of users.

Altinn Platform does not have a own copy of ER. It currently uses Altinn II plaform as source for register.

The register component is an ASP.Net Core MVC Application exposing REST-API to Altinn Apps.

The solution is now available at and all resources are avaiable through endpoints defined below.
