From number to fields, in one call

The KVK number is the key. We attach the website to it, and what a company does and uses.
  1. 1

    The number

    You send a KVK number, or a domain if you only have a website.

    00000002
  2. 2

    The link

    We know which website belongs to which number, and measure each week how accurate that is.

    voorbeeld.nl00000002
  3. 3

    What's behind it

    Fields on what the company does and uses, with what we don't know marked as unknown.
