History
Russia and Kazakhstan retained their shared use of numbering zone 7 under an intergovernmental agreement that entered into force on 3 December 2025. Kazakhstan uses allocations beginning +7 0, +7 6 and +7 7 under the shared plan.
The prefix +7 alone is not sufficient to identify a number as Russian. Russia also spans 11 time zones, so local time must be calculated for the specific city or region.
