Unrivalled coverage

Our TNS Network:

Operating out of offices in Brussels, TNS opinion coordinates a network of TNS and partner institutes in the EU and across the world to conduct online, telephone, face to face and qualitative research. Through our network we have a worldwide coverage comprising over 150 offices across 5 continents. 

ESOMAR and/or WAPOR Membership

The members of our network have ESOMAR and/or WAPOR memberships: the managers of the institutes belonging to our network are ESOMAR members. They comply with the ICC/ESOMAR code (International Code of Marketing and Social Research Practice) and the WAPOR/ESOMAR Guide to Opinion Polls. Some of them are also members of WAPOR. In addition, all our network members also comply with national rules on the protection of personal data.

ISO 9001, ISO 20252 or equivalent

The vast majority of our members are certified or are in the process of certification with respect to both the design and implementation of surveys. We have more ISO 20252 certified countries than any other market research agency.
