Short answer

Altinn is a Norwegian public internet portal for digital dialogue between businesses, private individuals and public agencies, with over 1,500 forms and digital services. You log in through ID-porten with MinID, BankID, Buypass or Commfides. More than 4 million private individuals have an inbox there, and over 1 million businesses are registered users.

Why

  1. The Norwegian Digitalisation Agency (Digdir) coordinates the Altinn cooperation and manages the platform on behalf of the agencies that own the services.
  2. A private individual's inbox is linked to the national identity number, and a business's inbox to its organisation number.
  3. Altinn says logging in with MinID corresponds to security level 3, the second-highest level, which gives access to most services.

Details

Public agencies use Altinn to send forms, documents and decisions, and by December 2019 more than half a billion had passed through it. Among the popular forms is the Directorate of Health's application for authorisation and licence as health personnel. The Tax Administration has moved its own forms and services to skatteetaten.no, and you see the same messages from it whether you log in to Altinn or to skatteetaten.no.

Tip

If you have a D-number and no BankID, order MinID at minid.no, since it gives access to most services in Altinn.

What may differ

Without a Norwegian national identity number or D-number, you can only log in with a username and password, which gives access to a few services.
