Check a Danish company by API: CVR and accounts

CVR (Erhvervsstyrelsen) · partly covered · checked 11 November 2026

The official route

Erhvervsstyrelsen, the Danish Business Authority, runs the CVR register. For developers it comes in two parts.

Filed annual reports are open. A public search index at distribution.virk.dk/offentliggoerelser takes a CVR number without a key and returns links to the XBRL documents on regnskaber.virk.dk. It holds every annual report filed digitally, for all years. We found no terms of use specific to this index (checked 2026-11-05). The authority's GDPR page for annual reports says they are published in CVR immediately and kept without time limit. It states no reuse conditions.

The CVR register data itself (status, board members) is on other indexes of the same host, and those require credentials from Erhvervsstyrelsen. You apply for system-to-system access with the "Anmod om adgang" form. The account is free.

Where it gets hard

The application takes about 3 weeks. We applied by 2026-11-08 and are still waiting.
Until that access comes we have no register source for a status such as "under konkurs".
The accounts index answers over plain HTTP only.
The robots.txt of the document host regnskaber.virk.dk disallows all crawlers. We fetch single documents that the index links to, one per requested year, and do not crawl.
Small (class B) companies may publish gross profit in place of revenue.
The index also holds the name of the general meeting's chairman. We never request it.

One call

Status from the CVR register, board members and bankruptcy. They wait on the access we applied for.
For a company without an LEI, the identity is only the name in its filed accounts.
