Organization Registry (OrgReg)

The Organization Registry contains a copy of all organizations in the Norwegian Central Coordinating Register for Legal Entities (known as "BRREG"), and offers an API with lookup on organization numbers, and an event API which allows a consumer to be notified when information changes.

Questions or feature requests can be sent to utv_virksomhet@nhn.no.

Environments

Synthetic test organizations

BRREG also maintains a register for synthetic organizations, where the organization number starts with 2 or 3, opposed to real organization numbers which start with 8 or 9. In the test environment, you will find synthetic organizations in addition to real organizations. To find or search for synthetic organizations, you can use Tenor.

You should always use synthetic organizations in test environments.

Authentication and authorization

The organization registry is secured with HelseID, using machine-to-machine authentication and authorization. The external system must authenticate by sending a DPoP access token and DPoP proof, and the access token must include the scope nhn:orgreg/read.

Read more about the DPoP on the HelseID pages here: DPoP.

Data format

Json

The organization registry offers the same json dataformat as in the BRREG API.

When looking up a sub-unit by organization number using the main unit endpoint (/brreg/underenheter/) will return 404 - Not found, and the same vice versa. The combined endpoint (/brreg/{organisasjonsnummer}) will return a response both for a main unit and a sub unit, provided that it exists in the registry.

FHIR

The organization registry also offers a FHIR data format on the endpoint /Organization/{organisasjonsnummer}. This endpoint returns the FHIR resource Organization - FHIR v5.0.0 (hl7.org).
