The Schengen Information System (SIS) is a database shared by all Schengen Area States, containing information about sought after, missing or pursued persons and about stolen or missing vehicles and other objects (mainly identification documents, vehicle registration documents or license plates).

In the visa process, an entry in the SIS on the applicant can be a basis for visa refusal – based on Article 32 of Regulation (EC) No 810/2009 (Visa Code). 

Persons who have been denied entry in the Czech Republic / Schengen Area based on an entry in the SIS can request an explanation from the institution, which has made the entry. In the Czech Republic, it is the Police of the Czech Republic. The contact address is the Police Presidium (Policejní presidium), P.O.BOX 62/K-SOU, Strojnická 27, 170 89 Praha 7.

In accordance with the principles of protection of data, the Schengen Agreement recognizes certain rights pertaining to all individuals. These rights primarily include:

• right to access to personal data about the applicant in the SIS database;
• right to correction or deletion of faulty data about the applicant;
• right to request domestic institutions for data protection to verify the personal data of the applicant in the SIS database, as well as verification how they are used;
• right to launch a court or administrative proceedings regarding correction or deletion of faulty data or compensation.
