A system for managing opt-out instructions includes a global opt-out service and opt-out store in communication with regional subsystems. The opt-out service maintains a global opt-out store database of consumers for whom opt-out instructions have been received. The opt-out store includes no personal data, but instead contains only anonymized data. Before consumer data is utilized, an anonymized identifier is created by a regional data anonymizer and transmitted to the opt-out store. The opt-out instructions are applied by searching for a match in the opt-out store for a matching anonymized identifier. In this manner, the system may comply with privacy laws and regulations concerning the transmission of personal data outside of a region, while still providing a global opt-out service.
