Geographic Coverage and Administrative Jurisdiction
The +7 391 country and area code combination is the international dialing prefix for the Krasnoyarsk Territory (Krasnoyarsk Krai), a vast federal subject of Russia located in Siberia. This geographic area code serves the administrative center, the city of Krasnoyarsk, as well as numerous surrounding towns and settlements within the region. As a geographic code, it is tied to a specific territory, and its use is governed by the Russian national numbering plan, which follows ITU-T E.164 recommendations.
Key localities served by the +7 391 code include:
- Krasnoyarsk (the administrative capital)
- Divnogorsk
- Sosnovoborsk
- Zheleznogorsk (closed city)
- Zelenogorsk (closed city)
- Many rural districts and settlements within the Krasnoyarsk Territory
Dialing Formats and Instructions
For callers within Russia, the national trunk prefix is 8. Therefore, to call a number in Krasnoyarsk from another Russian region, you would dial 8-391-XXX-XX-XX. For international callers, the format is +7 391 XXX-XX-XX (or 007 391 XXX-XX-XX from some countries). The subscriber number is seven digits long, and the area code is three digits, resulting in a total national significant number length of 10 digits (excluding the trunk prefix).
When dialing locally within the same area code, it is common to omit the area code and dial only the seven-digit subscriber number. However, for clarity and to avoid misdialing, using the full national format is recommended, especially when calling from mobile phones.
Overlay and Numbering Considerations
As of the latest updates, there is no overlay code for the Krasnoyarsk Territory; the 391 code is the sole geographic area code for the region. This simplifies dialing procedures. However, due to the region's large geographic size, the code covers multiple local exchanges, but no additional area codes have been introduced. Callers should always verify the correct number length and format with the recipient to ensure successful connection.
For businesses and individuals, it is important to note that while +7 391 is a geographic code, many numbers in Russia can be ported to mobile networks or VoIP providers, which may affect routing and location identification. Nevertheless, the code remains officially designated for the Krasnoyarsk Territory.
