How do we collect data?

Here's an overview of the most frequently asked questions

Bisnode Belgium collects data from consumers through surveys about their consumption habits which they can voluntarily fill in in order to receive personalized offers, participate in contests or take advantage of promotions. For an example, see

Bisnode also concluded partnerships with commercial companies which provide information about their customers.

Finally, data are also completed with a certain amount of statistical information, such as the ones provided by Statistics Belgium.  Examples of collected informations: average income of the neighborhood where people live,  percentage of gardens, of house owners, ...

All this data is collected and merged to shape our "consumers" file which is marketed.

Yes, we can complete your data with deduced or supposed data. For example, if you live in a single-family home and if, at the very same address, we have data from someone else, we deduce that this person is a member of your household. This means that we are guessing there may be some family connection between you, without actually knowing your civil status. Actually this kind of information is interesting in a marketing point of view to help advertisers avoid sending the same mailing to different members of the same family.

Yes we can establish marketing profiles.

It means concretely that we can put you into "marketing segments", for instance "families with children", "retired people", "people living the city X"... 

This categorization will result in proposing your data to companies that sell products or services that we feel are more likely to be of interest to you. At the opposite, it also allows companies to avoid contacting you for products or services that are very unlikely to be of interest to you.

These criteria can be purely geographical, so a company will ask us a selection of people living within a radius of 10km from their shop or living in the city X. In a broader way, if we assume that you belong to a family with children, you will receive more ads for family cars, amusement parks, healthcare services to families ... If you are a retiree, you will rather receive advertisements on investment products or holidays ... Finally, if your house has solar panels, you may be more sensitive to some of the arguments related to environmental protection.

These profiles are not pre-established. We can build them according to the requests of our customers and we do not necessarily keep them.

No. We simply evaluate what we call in our jargon your "marketing potential". The extent to which your profile suggests you may be more or less interested in a specific product or service than the average consumer. This profile may just be a score (for example, for a "family" car model, a family with a child will receive a higher score than a young single). The consequence will be for example that you will probably receive an advertisement different from the sent to your neighbour. This does not mean that your neighbour will not be able to acquire the same product or service under the same conditions. It means simply that the content of the ad he will receive in his mailbox or email box will be different from yours.

It can happen that the score related to your profile is combined with other scores built by our clients. In this case, the final interpretation of all scores or profiles is the responsibility of our clients. If our clients use these combined profiles in a way that could have a legal effect on you or affect you significantly, they commit themselves to inform you and comply with the applicable legal dispositions.

These data come from Statistics Belgium or any other institution that could make them available on the market, which is commonly called Open Data. These anonymous data are related to a neighbourhood or group of individuals and therefore not related to a specific person.

Bisnode Belgium can also build its own statistical models.

Your authorization

Legal basis: Article 6a of GDPR:

Especially when you freely communicate data on our site (or any other survey that we or our partners may edit) or when you contact us directly for a specific request or when you freely consent to the processing of your data by any other channel.


Based on the pursuit of our legitimate interest, as part of our marketing activities (including improving the quality of our customers' databases)

Legal basis: article 6f of GDPR:

We have a legitimate interest in continuing the activities just described above. Indeed GDPR provides in its preamble No. 47 that activities related to "direct marketing" constitute a legitimate interest.

It goes without saying that this interest must be constantly weighed against the rights of the people registered in our file. It is to this end that we strive to be as transparent as possible regarding the use of the data and we respect scrupulously the GDPR as for the rights of the person (see further)

This legal basis is used for any data processing for which we do not ask for your explicit consent.


In order to guarantee your rights, we have implemented a series of measures:

 1. First of all, we scrupulously check that our source business partners respect the GDPR, whether it is at the level of the collection of your data or at the level of the information they give you about the processing of your data. In particular, we ask them to be as transparent as possible regarding the transmission of data to Bisnode Belgium and to refer to these web pages for more information on our activities.

2. We have procedures in place to allow you to exercise your rights easily (see here).

3. Suppose you do not object to receiving advertising but you would prefer to receive it via us, but only via a specific medium (e.g. only on your postal address but not by phone), then you can simply report this to us with this form.

4. The security of your data is of paramount importance to us, and we do regular internal and external checks to ensure that the tools and procedures put in place work properly.

5. We have appointed a "Data Protection Officer" to ensure that your rights are respected (see here). 

6. Finally, in compliance with the GDPR, we carried out a data protection impact assessment. This document analyzes all the possible risks of harm to your data and all the measures to be taken to avoid or limit this risk to a maximum. The recommended measures have been implemented in our IT system and in our procedures.

Our activities evolve around personal data. The conservation period of this data must be long enough to maintain the best possible quality and thus reduce the risk of errors. Consequently, we keep your data for a period of 15 years starting from their last recording in our database. It is possible that another source also communicates your data to us, in this case, the delay starts again from this new communication.

This relatively long time is also explained by the fact that we carry out many treatments on personal data. The companies on whose behalf we work require us to keep the traceability of these treatments.

As we already indicated before, it goes without saying that if you wish that we do not use your data any longer for advertising purposes (right of opposition) or if you wish to be forgotten, you just have to follow the procedure described here. In this case, the conservation during 15 years is obviously not applicable and your request will prevail.

We make every effort to ensure the highest confidentiality and security for your data. In this context, we take all necessary technical and organizational measures.

In this context, our network, our infrastructure and our information systems are protected. Access to your personal data is authorized only to the persons who need it for the accomplishment of their mission. They are held in strict professional discretion and must comply with all the technical prescriptions provided to ensure the confidentiality of personal data. We want to prevent unauthorized people from accessing, processing, modifying or destroying your data.

In the case of data breaches, which may entail risks to your privacy, you are personally notified, as is the Commission for the Protection of Privacy, in accordance with our legal obligations. In this case, we will make every effort to stop this state of affairs as quickly as possible and to limit all the consequences.

Some of Bisnode's clients may transmit some of your data outside European Union. It is obvious that all the processing of your data carried out there is protected in accordance with the legal provisions. We make sure that the envisaged treatments respect a level of protection of your data equivalent to the protection existing in the European Union, in particular by signing the contractual clauses of the European Commission.
