Area Code 390 – Republic of Khakassia

Geographic Overview and Assignment

The +7 390 area code is a geographic National Destination Code (NDC) assigned to the Republic of Khakassia, a federal subject of the Russian Federation located in southern Siberia. This code covers the entire republic, including its administrative capital, Abakan, as well as other significant urban centers such as Chernogorsk, Sayanogorsk, and Abaza. The numbering area is part of the Russian national numbering plan, which follows ITU-T E.164 recommendations. When dialing from abroad, callers must use the full international format: +7 390 followed by the subscriber's seven-digit local number, resulting in a total of 11 digits after the international prefix (e.g., +7 390 XX XX XXX).

Dialing Formats and Procedures

For domestic calls within Russia, the trunk prefix '8' is used instead of '+7'. Therefore, a call from Moscow to Khakassia would be dialed as 8 390 XX XX XXX. Within the same area code, local calls may be dialed using only the seven-digit subscriber number, depending on the specific operator's requirements. However, due to the widespread adoption of mobile and VoIP services, it is often necessary to include the area code even for local calls. For international callers, the process is straightforward: dial the international access prefix (e.g., 011 from the US and Canada, 00 from most European countries), followed by 7 (the country code for Russia), then 390, and finally the seven-digit local number. It is essential to omit any leading '8' or '0' that might appear in local directories.

Geographic Coverage and Administrative Details

The Republic of Khakassia is a region with a population of approximately 530,000 people. The area code 390 is dedicated to fixed-line telephony services, serving residential and business customers. The region's telecommunications infrastructure is well-developed, with fiber-optic and DSL broadband widely available in urban areas. The code is administered by the Russian Federal Communications Agency (Rossvyaz), and number allocation follows the national numbering plan. As of the latest updates, there are no overlay codes planned for this region, meaning that the 390 code remains the sole geographic code for Khakassia.

Practical Guidance for Callers

When calling a fixed-line number in Khakassia from a mobile phone within Russia, it is advisable to include the area code to avoid misrouting. For example, a call from a Russian mobile to a landline in Abakan would be dialed as +7 390 2XX XX XX (where '2' is the central office code for Abakan). For international callers, ensure you have the correct local number, as the seven-digit format is strictly enforced. If you encounter difficulties, check whether the number has been migrated to a VoIP service, which might require alternative dialing procedures. Always verify the number with the recipient to avoid errors, especially when calling from abroad.
