The purpose of this Code of Data Matching Practice is to help ensure that the Auditor General for Wales and his staff that are involved in data matching exercises comply with the law, especially the provisions of the Data Protection Act 1998, and to promote good practice in data matching.

It includes guidance on the notification process for letting individuals know why their data is matched and by whom, the standards that apply and where to find further information.
