A telephone number corresponding to an incoming telephone call may be utilized to obtain information associated with the incoming call. If it is determined that the telephone number does not match records stored on the device on which the call is received, a request may be sent from the receiving device to an external device to obtain information associated with the incoming call. The request may be directed to a remote contacts application, another device listed in a data store of the receiving device, or to the calling device itself. When a response is received, the information may be displayed or otherwise utilized by the receiving device.
