Required Documentation for PCI DSS

PCI DSS is probably the most critical compliance standard your organization will need to comply with if your organization processes payment card transactions or has customers who process payment card transactions. If your organization does not comply with PCI, you may lose authorization to process these transactions or, if you don’t process transactions, you may lose the business of customers who rely on your service for their own transaction processing activities. Part of complying with PCI will involve producing significant amounts of documentation related to managing your IT environment. This documentation will be used to support your answers if you are filling out a PCI DSS Self-Assessment Questionnaire (SAQ) or support your auditor’s testing if you are required to have a PCI on-site assessment performed (QSA assessment or Report on Compliance (ROC)).

To help determine what documentation is required when completing a PCI SAQ or ROC, we have read through PCI SAQ D, the assessment guidance for PCI ROCs, and outside sources.

The table below contains the documentation required for each of the 12 PCI DSS requirements outlined by the PCI Security Standards Council.
