Frequently asked questions

Where do these locations come from?

Registry records where they list a location (FedRAMP Marketplace, Cyber AB); firm contact pages for SOC 2-only entries. No county or extra office is inferred from a ZIP code.

Does a firm listed here serve my area?

A listed address is not proof of a service area. Contact the firm to confirm availability and engagement scope.

Firms are listed from official registries, each with its own as-of date. Locations are shown only where the registry or the firm's own site provides them. A listing records registry status, not an endorsement, and directory information may change. SOC 2 is a CPA attestation report, not a certificate. pa.tax is independent: listed firms pay nothing for inclusion, ranking or referrals, and firms are listed alphabetically.
