PURPOSE: To obtain a data communication equipment performing sure data communication with a prescribed destination by providing a recognition means recognizing a destination signal and a comparison means comparing the destination data sent from the destination and a destination identification signal.

CONSTITUTION: When the operator uses a telephone set 4 to makes a call, a dialing detection section 5 detects is and outputs a telephone number signal to a main control section 6. The control section 6 sends the inputted telephone number signal to a display section 10 to display the telephone number. Since the information relating to an opposite facsimile equipment is inputted in a facsimile information field (FIF) storing call station identification, transmission station identification and caller station identification signal sent from the opposite station, the control section 6 compares the telephone number called manually by the operator with the telephone number inputted in the FIF and makes transmission only when they are coincident. Thus, the picture transmission to a different destination in error is avoided.
