CONSUMER DATA REQUEST FULFILLMENT SYSTEM

A consumer data request fulfillment system enables a client to easily and speedily obtain consumer contact data that the client does not already possess. The consumer data request fulfillment system provides bulk consumer data to a client upon request. The bulk data may include, for example, encrypted consumer identifiers (IDs), and/or a partial subset of consumer contact information for a particular specified segment of consumers. The client may then request from the system a full set of consumer contact information. For example, the client may send a request for consumer contact information by identifying particular consumers by their consumer IDs. The consumer data request fulfillment system will then provide the full set of consumer contact information to the client. The requests and request fulfillments are advantageously accomplished automatically by the consumer data request fulfillment system, enabling the client to obtain consumer contact information conveniently and rapidly.
