Quality of the Business Register

A correct and up-to-date Business Register is essential for legal security when doing business. For this reason, the quality demands for authentic data are high. This concerns data which the law requires to be recorded in the Business Register. For example, the trade name, KVK number, owner's details, address, and legal structure.

Quality standards

The quality standards for the authentic data are: 

  • Completeness of data 99.8 %: the extent to which authentic data are complete in the registrations. 
  • On-time data processing 98.0 % : the extent to which digital submissions are processed within 1 working day, and submissions by post within 5 working days. 
  • Accuracy 99.5 % : the extent to which the authentic data that have been recorded in the Business Register are identical to the source documents. 

How KVK ensures the quality standards are met

Checks, and spot checks

KVK carries out automated checks and in-house spot checks. Also, an accountant researches the accuracy of the authentic data in the Business Register every 3 years. 

Authorised employees

Only employees with the required level of authorisation are able to register organisations and make changes.

Automated processes

Automated processes ensure registrations are complete and alert errors directly upon entry. 

Connected to BRP and BAG

The Business Register is connected to the Basisregistratie Personen (municipal personal records database, BRP) and the Basisregistratie Adressen en Gebouwen (addresses and buildings key register, BAG). These connections ensure data are and remain correct and up-to-date.

Feedback from government and businesses

Also important are feedback and signals from governmental and private parties. KVK uses this information to keep the Business Register complete, correct, and up-to-date. The Belastingdienst (Netherlands Tax Administration) for example reports inactive companies, and KVK acts on that information.
