The national data regulator maintains a searchable database of data controllers so consumers can find their point of contact and easily retrieve their data policies.
United Kingdom: Information Commissioner’s office maintains a searchable register of data controllers. Entries for each controller contain their date of registration, the expiry of this registration, their postal address and what personal data is processed.
Argentina: A similar service to that found in the United Kingdom exists, showing the contact details of a data controller.
Existing legislation may not require the data protection regulator to make registration records public.
Online registers can be limited in use, because their interfaces are difficult to use or the data isn’t available in an open format.
The data covered in online registers may not be extensive enough.
