Start by deciding how the business will confirm the consumer is the person making the request, or a person authorized to act for them, using commercially reasonable methods. The workflow should explain what information may be requested, what sources can be matched, what happens if the business cannot verify the request, and which requests can be routed to a different handling path.
For access, deletion, and correction requests, the business may ask for information needed to verify identity, and any personal information collected for verification must be used only for verification and not for unrelated purposes.
