+7 is an ITU country code for telephone numbering. It was originally used by the Soviet Union, then after the 1991 dissolution of the Soviet Union by the fifteen successor states. Between 1993 and 1998 the majority of these received country codes with 3xx or 9xx prefixes, and the +7 prefix is now only in use by Kazakhstan, Russia (occupied lands of South Ossetia (Samachablo) and parts of Abkhazia by Russia).
