Article 16 sets out the right to rectification of inaccurate data and Recital 65 provides additional guidance.

This right reflects the existing right, and explicitly states, having regard to the purpose for processing the personal data, data subjects have the right to obtain completion of incomplete personal data "including by means of providing a supplementary statement".

  If the controller has disclosed the personal data, Article 19 applies and the controller must advise each recipient of the data in question about the rectification and, if requested, the controller must inform the data subject about those recipients.
