Here is the record from Enhetsregisteret: name, organisation form, industry, addresses and former names, with the source and licence attached.
What you get
Enhetsregisteret, as tools your assistant can use
Six read-only tools over the register, each answering with the source attached. Your assistant picks the right one from your question.
Search by name, address or place
Ranked search over current and former names, addresses and websites, filtered by municipality, organisation form, industry, size or public bodies.
Resolve a name to the right organisation
Turns a name — including spelling variants and former names — into ranked candidates, and says when it is ambiguous instead of guessing.
See the structure
Parent organisations up to the top, agencies under a ministry, and the sub-units where a company actually operates.
Key financials, when you ask
Key figures from the latest annual accounts in Regnskapsregisteret, fetched only on explicit request and labelled with their year.
Codes and filters explained
Organisation forms, municipalities, industry codes and sectors with counts, so a question like “limited companies in Bergen” becomes an exact filter.
Why this one
Why not just look it up yourself?
The data is open, and you can always read it at the source. What Brreg sells is having it answer inside the assistant you already have open, kept up to date by us.
The register’s own website
Free, complete and legally binding — and a site you open, search and read yourself, one company at a time. Brreg answers in the middle of what you were already doing, and still sends you to the official record when the answer has to hold up.
Running an open connector yourself
The same open data is there for anyone to index. Then the download, the weekly refresh, the address matching and the server are yours to keep running. Here they are ours: nothing to install, nothing to update.
Company-data platforms
Built for teams, priced for teams, and usually sold with a contract. Brreg is one plan, bought in a minute, made for one person who needs the register at hand.

“Find the company called Equinor ASA and show its key figures for the latest year”
Resolves the name to one organisation number, then looks it up with key financials from the latest filed annual accounts.
entity_resolveentity_lookup

snapshot_status
Who it is for
For anyone who checks Norwegian organisations
Accountants
Confirm client details, organisation forms and filed accounts in the middle of your work.
Sales and CRM
Clean up customer lists: right name, right number, still active.
Due diligence
Check structure, status flags such as bankruptcy or dissolution, and key figures before you sign.
Journalists
Trace former names and who sits under whom, with the source cited.
Developers
A typed, paged MCP interface with structured errors instead of scraping.
Built to be trusted
Open data, handled with care
Source and licence on every answer
Every result names Brønnøysundregistrene and carries the NLOD attribution, so your assistant can cite it.
Not the official register
Brreg is an independent service on open data. For anything legally binding, check virksomhet.brreg.no.
No register of persons
Organisations only: no roles, no board members, and personal details held back for sole proprietorships.
Removals honoured within 24 hours
When Brønnøysundregistrene removes an entry from open data, it disappears from Brreg within a day.
