What Is the CVR API?
CVR (Det Centrale Virksomhedsregister) is Denmark's central business register, operated by Erhvervsstyrelsen. Every business carries an 8-digit CVR number; production units get separate 10-digit P-numbers.
The official access route is the system-to-system interface at distribution.virk.dk: free and near real-time, but you apply by email, sign a declaration, and then query an Elasticsearch endpoint with its own query language and no support. Financial statements come as separate XBRL and PDF filings rather than fields, and records flagged with reklamebeskyttelse are restricted for marketing use.
CompanyData packages Danish register data as a straightforward REST API: CVR number, legal name, binavne, legal form, status, the official DB07 branchekode, plus revenue, employee counts, email, phone and website. Sign up, get a key, first call in minutes, and the same API covers 200+ other countries.
