A text mail system in which a pseudo destination subaddress randomly generated at a call receiver side at the time of receiving an incoming call from an integrated services digital network is used to manage the storing or reading out operation of various sorts of messages in a mail box. The text mail system, which uses the pseudo destination subaddress as a box number based on the property that the pseudo destination subaddress is randomly given for each incoming call, can secure a high mail confidence.
