Telephone numbers in Russia
Telephone numbers in Russia are under a unified numbering plan with Kazakhstan, both of which share the international code +7. Historically, +7 was used as the country calling code for all of the Soviet Union. Following the Soviet break-up, all of its former republics, save for Russia and Kazakhstan, switched to new country codes. Following Abkhazia's secession from Georgia, Abkhazia switched to the Russian telephone codes +7 840 for landlines and +7 940 for mobile phones, though it still can be reached via the Georgian telephone code +995 44.

Russia uses a four-level (local, zone, country, international) open dialing plan. Local telecommunications regulators had planned to abandon this system and change to a closed dialing plan at all levels by 2009, but postponed the changeover until 2010, later pushed once more until 2012 and finally approved for implementation in the period of 2020–2025. Currently, all national subscriber numbers consist of 10 digits (excluding any prefixes), with 3 digits for an area code and a 7-digit individual number which includes a zone code (up to 2 digits).
