Analysis apps that use this source

Ready-made tools built on GLEIF LEI — global legal entity identifier data. Use them directly in the browser, or wire the same data into your own analysis via the API below.

Company profile

Cross-referenced company profile in a single lookup — Brreg, GLEIF LEI, OpenCorporates and Wikidata, with Nordic name matches from CVR (DK) and YTJ (FI). KYB, journalism and investor analysis.

Norwegian continental shelf

Oil and gas production, fields, wells and production licences.

LEI search — global group structures

Search more than 2.6 million LEI records globally — parent/child relationships across jurisdictions, BIC/ISIN lookups and company verification. Free from GLEIF.

Nordic company register

One search across the company registers of Norway, Sweden, Denmark and Finland. Norway and Finland are covered by the national registers (Brreg, YTJ); Sweden and Denmark by GLEIF LEI, since Bolagsverket's and CVR's own APIs require an agreement. Shows which register answered, and retrieves the GLEIF-verified group structure across borders. For a single real-time lookup that also covers Iceland, see the NSG app.

Finanstilsynet register

Look up which companies hold a licence from Finanstilsynet — search by name or organisation number.

Shareholder search

Ownership and control for Norwegian companies — parent and subsidiary entities from GLEIF level 2, ownership and control roles from Enhetsregisteret, and the shareholder list as of 31 Dec from the Skatteetaten Shareholder Register where available.

Beneficial owners

Assess beneficial owners (≥ 25% ownership) in Norwegian entities under the Norwegian Anti-Money Laundering Act section 14 — limb by limb from Enhetsregisteret (the Central Coordinating Register), the register of roles and GLEIF group relationships — and screen every identified party against a consolidated sanctions list. KYB/AML for auditors, banks and lawyers.

KYB report

Complete Know-Your-Business report for Norwegian companies: Brreg base data, roles and board, 3 years of accounts, OpenSanctions screening and GLEIF LEI in a single lookup. With a heuristic risk score.
