Area Code 424 – Sakhalin Region

Overview of Area Code +7 424

Area code +7 424 is the national destination code (NDC) assigned to the Sakhalin Region (Sakhalinskaya Oblast) of the Russian Federation. This geographic code covers the entire island of Sakhalin and the Kuril Islands, including the administrative center Yuzhno-Sakhalinsk, as well as other major towns such as Korsakov, Kholmsk, Okha, and Severo-Kurilsk. The code is used for fixed-line (PSTN) services within the region, and it is part of the Russian national numbering plan under the international country calling code +7, which Russia shares with Kazakhstan.

Dialing Formats

When calling a fixed-line number in the Sakhalin Region from within Russia, subscribers must dial the trunk prefix '8', followed by the area code '424' and the subscriber number. For example, a local call to a number in Yuzhno-Sakhalinsk would be dialed as: 8 424 XX XX XX (where 'XX XX XX' represents the six-digit local subscriber number). From abroad, callers must dial the international access prefix (e.g., '00' in most countries), then Russia's country code '+7', the area code '424', and the subscriber number, omitting the trunk prefix. Thus, an international call would be formatted as: +7 424 XX XX XX.

Geographic Coverage and Administration

The Sakhalin Region is a federal subject of Russia, located in the Far East. The area code 424 is administered by the regional branch of Rostelecom and other licensed fixed-line operators. The region's numbering capacity is managed under the Russian Federal Communications Agency (Rossvyaz). The code is strictly geographic, meaning that the number is tied to a physical location within the region. This is important for emergency services and law enforcement, as the code helps route calls to the appropriate local dispatch centers.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Sakhalin Region; the 424 code is the sole area code for the region. However, as with all Russian geographic codes, the number of digits in the subscriber number may vary depending on the local exchange capacity. In Sakhalin, subscriber numbers are typically six digits, but some smaller towns may use five-digit numbers. Callers should verify the correct number length with the called party or directory services. For fixed-line-to-fixed-line calls within the same area code, it is often possible to dial only the subscriber number, but this is not guaranteed across all exchanges; using the full national format is always safe.

Caller Instructions

For local callers within the Sakhalin Region: if you are calling from a fixed-line phone, you may need to dial '8' first to access the trunk line, then the area code and number. For mobile callers, simply dial +7 424 followed by the subscriber number. For international callers, always use the plus sign (+) or the international exit code of your country, then 7 424 and the subscriber number. Be mindful of time zones: Sakhalin is in the Vladivostok Time Zone (UTC+11), which may affect business hours.
