Abstract: A technique for enrolling an individual for a service is described. During this enrollment technique, a match between an identifier provided by and associated with the individual is determined with an existing identifier associated with another service. If there is a correspondence between the service and the other service, enrollment information from the other service is used in an enrollment process for the service, which allows a subset of the enrollment process to be performed. Otherwise, the full enrollment process for the service is performed. In this case, reconciliation of the identifier and the existing identifier (for example, asking the individual if they also use the other service) is delayed until after the enrollment process is completed.
