Correct the information in existing active systems and instruct each service provider or contractor that maintains it under the written contract to make the correction or enable the business to do so. Archived or backup copies may wait until the relevant system is restored, accessed, or used.
Tell the consumer whether the request was completed. If the consumer asks, disclose the specific pieces maintained and collected about them so they can confirm the correction; for Social Security numbers, government identifiers, financial or medical account numbers, passwords, security answers, and unique biometric data, provide a confirmation method without disclosing the sensitive value itself. The case file should show the old and corrected value where retaining that comparison is necessary and lawful, each affected system and recipient, the instruction date, completion status, and any backup-system dependency.
Privacy operations should own the case and timing. The data owner decides the authoritative value, engineering or operations changes systems, recipient owners transmit instructions, and privacy or legal reviews exceptions, material disputes, and denials.
