A method and an apparatus for providing a contact through interworking with a Social Network Service (SNS) are provided. The method includes receiving, by a client using the other service through SNS interworking, a contact provided in the SNS, determining whether the other party's client having subscribed to the same service as that of the client is present in the received contact, and informing a user of the determination results. Based on the determination results, the client may determine subscription/non-subscription of the other party's client to the service, and may send an invite request for the service if the other party's client has not subscribed to the same service as that of the client. By doing so, the number of targets, subscription/non-subscription of which to a specific service can be determined, may be extended.
