12.5.3 Scope review after significant organisational change

Service providers only: when the organisational structure changes significantly, the entity must carry out and document an internal review of the effect on PCI DSS scope and on which controls apply, and report the results to executive management. The guidance gives examples of such changes: mergers or acquisitions and major changes or reassignments of personnel responsible for security controls. Applicability: applies only when the assessed entity is a service provider. Objective under the customized approach: scope gets reconfirmed after a major organisational change. Future-dated: treated as a best practice up to 31 March 2025 and mandatory since then.

Version 4.0.1 is the active version; 4.0 has been retired. Appendix A1 applies only to multi-tenant service providers, A2 only to card-present POS POI terminals that still use SSL or early TLS, and A3 only when a payment brand or acquirer requires it. Which requirements apply to you follows your validation type.
