Area Code 878 – Karachayevo-Cherkessian Republic

Overview of Area Code +7 878

Area code 878 is a geographic numbering plan area within the Russian Federation, assigned to the Karachayevo-Cherkessian Republic (Karachay-Cherkessia). This region is located in the North Caucasus federal district, bordering Georgia to the south. The code serves the entire republic, including its capital, Cherkessk, and other key towns such as Karachayevsk, Ust-Dzheguta, and Zelenchukskaya.

As a geographic code, 878 is used for fixed-line (PSTN) services, and since the liberalization of the Russian telecom market, it may also be used for VoIP and other fixed-line alternatives. The code is part of the national numbering plan under the international country code +7, which Russia shares with Kazakhstan.

Dialing Formats

When calling a fixed-line number in Karachayevo-Cherkessia from within Russia, the national trunk prefix 8 is used, followed by the area code and the subscriber number. For example, to call a number in Cherkessk, you would dial:

• 8 (878) 2X-XX-XX (national format)

From outside Russia, callers must use the international access prefix (e.g., 00 from most countries, or +), followed by the country code 7, the area code 878 (without the leading 0), and the subscriber number. For instance:

• +7 878 2X-XX-XX (international format)

Note that the subscriber number length in the 878 area is typically 7 digits, making the total national significant number (NSN) 10 digits, excluding the trunk prefix.

Geographic Coverage and Administrative Details

The Karachayevo-Cherkessian Republic is a federal subject of Russia, and its numbering resources are administered by the Ministry of Digital Development, Communications and Mass Media. The area code 878 is one of several codes in the North Caucasus region, with neighboring codes including 877 (Republic of Adygea) and 879 (Stavropol Krai).

There are no overlay codes or additional area codes for this republic; 878 is the sole geographic code for the region. This simplifies dialing for both local and international callers, as there is no need for 10-digit dialing within the region.

Caller Instructions

Local callers within the republic can often dial just the 7-digit subscriber number for local calls, depending on the operator's dialing plan. However, for calls from other regions of Russia, the full national format (8 878 ...) is required.

International callers should always use the +7 878 format to ensure proper routing. It is important to note that while +7 is shared with Kazakhstan, the area code 878 is exclusively assigned to Russia, so there is no risk of confusion.

For businesses or individuals in the region, having a local number with area code 878 can enhance local presence and trust. For those outside Russia, calling these numbers may incur international charges, depending on their telecom provider.
