E.164 is an international standard (ITU-T Recommendation), titled The international public telecommunication numbering plan, that defines a numbering plan for the worldwide public switched telephone network (PSTN) and some other data networks. E.164 defines a general format for international telephone numbers.
It is a closed telephone numbering plan in which all subscriber telephone numbers have seven digits, in addition to the three-digit area code. Under all-number calling, a numbering plan introduced around 1960, local calls within an area code were placed by dialing NXX-XXXX, omitting the area code, known as seven-digit dialing.
