What is the Internal Market Information System (IMI)?

The Internal Market Information System (IMI) is a tool developed and maintained by the European Commission to facilitate communication between national authorities involved in activities relevant to the internal market. It helps the authority of a member state to find the relevant authority in another member state, to exchange information. Currently, IMI supports 67 administrative cooperation procedures in 17 different policy areas. IMI can be adapted, with little or no development effort, to support further policy areas.

The Commission is responsible for the maintenance and technical operation of the system. In principle, it does not have access to personal data stored into the IMI. The cost of operating the system is financed through the EU's general budget. Member states appoint national IMI coordinators (known as NIMIC) who act as contact points for national competent authorities and the Commission.

Legal background

The IMI was originally created by Commission Decision 2008/49/EC, repealed and replaced by Regulation 1024/2012/EU of the European Parliament and of the Council of 25 October 2012 on administrative cooperation through the Internal Market Information System.  

Who can use the IMI ?

Only IMI users shall have access to IMI. IMI users are registered natural persons working for the competent authorities at national, regional and local level in the EU Member States, who get access to the online platform through which they can access the personal data stored in IMI.

Data protection rules

There are common principles applicable to processing of personal data in the system:

Purpose limitation: personal data can only be processed in a way compatible with the aim of the IMI (Article 13 of the Regulation);

Rules related to the retention of personal data (Article 14-15)
Special rules related to processing of special categories of data (Article 16);
