+7

+7 is an ITU country code for telephone numbering. It was originally assigned to the Soviet Union. After the 1991 dissolution of the Soviet Union, the code continued to be used by the fifteen successor states, the majority of whom switched to own country codes from the +3xx and +9xx ranges between 1993 and 1998.

Currently, the +7 country code is only assigned by ITU to two countries: Kazakhstan and Russia.

Russia has allocated parts of its national numbering range to the occupied parts of Georgia and Ukraine, all of whom are thus reachable using +7.
