IFF Research Services GmbH conducts telephone interviews and online surveys on a national and international basis for different clients.
In representative surveys, telephone numbers are randomly selected in a randomised process, so that even numbers that are not noted in public registries may be dialed. Your participation is, of course, voluntary.
Research institutes are subject to a self-commitment to display their phone number for market research calls. That way, the contacted person may identify the research institute placing the call without having to answer the call - for example due to absence.
We guarantee that our contact solely serves the purpose of market and opinion research without any intention for sales.
