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. Following the annexation of Crimea by Russia in 2014, the Republic of Crimea switched to the Russian telephone codes +7 978 for mobile phones and +7 365 for landlines, while the city ofSevastopol switched to the codes +7 978 for mobile phones and +7 869 for landlines, since 7 May 2015. Russia uses a four-level 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, with 3 digits for an area code and a 7-digit individual number which includes a zone code.
Long-distance and international prefixes
The international dialing prefix in Russia is "8~10"—callers dial "8", wait for a tone, and then dial "10", followed by the country code, area code, and number. The long-distance prefix is "8~". There are plans to change those prefixes to "0" for national and "00" for international dialing, to be implemented by 2020.
Placing long-distance and international calls
When making long-distance or international calls from a fixed line, a subscriber may choose either of two providers: Pre-Select or Hot-Choice. If a subscriber prefers Pre-Select, they call a prescribed free number and sign up initially for service. They may also sign a statement at the phone company indicating their choice of provider. With this provider, the prefixes and dialing procedures for non-local calls are the ones currently in use. The default regulation in Moscow is Hot-Choice. Available operators are:
The dialing pattern for Hot-Choice subscribers is different. After dialing "8", the subscriber waits for a tone and then dials the operator code either for a long-distance call or an international call.
Dialing pattern
Note: the tone signal after dialing "8" is compulsory on old analog exchanges and optional on digital exchanges.
Calls within a city or region
xxx-xx-xx, e.g.:
3-45-67
22-33-44
234-56-78
Local phone numbers in Russia may be made up of five, six, or seven digits. Moscow City has three area codes assigned: 495, 498 and 499:
when calling from any zone to 499: 8 499 xxx-xx-xx
when calling from any zone to 498: 8 498 xxx-xx-xx
when calling from any zone to 495: 8 495 xxx-xx-xx
Calls between these codes are local calls and are not charged at long-distance rates.
The dialing code 495 was introduced on 1 December 2005 to replace 095, in order to make it possible to adopt the ITU convention of 0 and 00 dialing prefixes for local and international dialing respectively. The old '095' dialing code, along with 19 other Russian area codes starting with '0', expired on 31 January 2006.
