Danish Company Lookup (CVR)

Look up Danish companies in the official Central Business Register (CVR) and get clean, structured JSON — by CVR number, company name, phone, email, email domain, or address. No API key required.

CVR is Denmark's authoritative business register, covering 700,000+ active companies. This actor returns the core registry data for each match: legal name, status, company type, industry code, employees, founding date, address, contact details, production units, and — importantly — the advertising-protection (reklamebeskyttelse) flag.

What it's for

• KYB / due diligence — verify a Danish company's identity, status, and registration.
• B2B prospecting & enrichment — turn a list of CVR numbers or names into full company records (see the legal note below before any marketing use).
• Reverse lookup — find companies by phone, email, email domain, or address.
• Research & datasets — pull structured Danish company data in bulk.

⚠️ Advertising protection (reklamebeskyttelse) — please read

Some Danish companies opt out of marketing contact. Each record includes a protected flag, but be aware the upstream data source often does not populate this field, in which case it returns null (unknown) rather than true/false. Do not treat null as "safe to contact."

Under the Danish CVR Act (§ 19 and § 22), you must not use the data of advertising-protected companies for direct marketing (calls, targeted mail, etc.), and you must mark them as protected if you pass the data to a third party. The excludeProtected option is conservative: it removes both protected companies and those with an unknown flag, leaving only confirmed-contactable ones. For any marketing use, verify protection status directly at datacvr.virk.dk. You are responsible for complying with these rules.
