The identifier may include a phone number or an email address of the intended recipient. The social information may include a name of the intended recipient, and/or a social-network profile of the intended recipient. The intended recipient may be a second user of the social-networking system, and the social information may be identified based on how many degrees of separation there are between the first user and the second user.
