Frequently asked questions

In a database comparison, we compare your address file with the listed Business Register details, and add any missing data. If you request an address file, you receive a file based on a number of criteria (such as SBI code or legal structure). We do not link this file to your address data. 

The files are matched by KVK number or address details. The details compared are a combination of: company name, postcode and house number, municipality (both postal and visiting address), and SBI code.
