Analysis apps that use this source

Ready-made tools built on Brønnøysundregistrene 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.

Municipality profile

A complete profile for a single Norwegian municipality — key figures, population trends and business activity gathered from SSB, Brreg and KOSTRA. To compare several municipalities side by side, use Kommune-sammenligning or Kommuneøkonomi.

Norwegian continental shelf

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

API status

Live health check for all KETL Data connectors — see which sources are responding right now, which require an API key, and which are temporarily down.

Wikidata — structured knowledge

Wikimedia's open knowledge graph — companies by org number (LEI/ISIN), Nordic municipalities with NUTS, and politicians per national parliament. CC0, cross-links Nordic registers.

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.

Voluntary-sector search

Search the Brønnøysundregistrene Register of Non-Profit Organisations — look up voluntary organisations by organisation number (org.no) or name, with ICNPO categories and grassroots-share (grasrotandel) status.

Company accounts register

Look up annual accounts for Norwegian companies by name or organisation number — income statement, balance sheet, equity ratio, debt ratio and operating margin from Brønnøysundregistrene, enriched with company status, industry code, roles and bankruptcy signal. Amounts are shown in the company's own reporting currency. The source provides the most recently filed financial year.

Patent search

Search Patentstyret's registers for patents, trademarks and designs — and pull one company's entire IPR portfolio, with how much of it is actually in force.

Client screening

Auditor red-flag screening in a single lookup — company status, solvency, earnings trend and sanctions name matches from Brreg, the Register of Company Accounts and the EU sanctions list, with explainable flags and source links for client acceptance (ISA 220).

Tax settlement

See what a Norwegian company actually paid in tax: effective tax rate derived from the annual accounts, measured against the nominal 22 % rate and against the special tax regime that applies to its industry. Open data, no sign-in.

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.
