Abstract: Systems and methods for identifying a counterpart of a messenger. An example method includes receiving an action signal of a user from the outside by a communication unit. User information related to the user is read from a database. An initial message and a response message including an identification indicator for identifying the user is determined based on the user information. A messenger server is requested to open a conversation channel, in which the user is designated as a counterpart, to transmit the initial message and to output the response message by the communication unit. The response message is received by the communication unit. The identification indicator output in the received response message and specifying a person corresponding to the identification indicator is checked as the counterpart.
