Registry traps
Most Visa registry rows are Third Party Agent or ISO registrations, not PCI DSS validations. Those are excluded. The Mastercard SDP compliant service provider list is the second registry-grade source.
Level 1 service providers
Registries list Level 1 service providers with a QSA-signed ROC or AOC. Smaller merchants and service providers self-assess and do not appear.
