Area Code 3636 – Kuznetsovsk, Rivne

Overview of Area Code +380 3636

Area code +380 3636 is a geographic National Destination Code (NDC) assigned to the city of Kuznetsovsk (officially renamed Varash in 2016) and its surrounding settlements within the Rivne Oblast of Ukraine. This code is part of the national numbering plan administered by the Ukrainian State Centre of Radio Frequencies (UCRF) under the framework of ITU-T E.164. The region is located in the northwestern part of Ukraine, near the border with Belarus, and is known for the Rivne Nuclear Power Plant, which significantly influences the local economy and population.

Geographic Coverage and Administrative Jurisdiction

The +380 3636 code covers the urban hromada of Varash, which includes the city itself and several adjacent villages. Administratively, Varash serves as a city of regional significance within Rivne Oblast. The primary settlements served by this code include Varash (Kuznetsovsk), and nearby localities such as Sopachiv, Stara Rafalivka, and others. The code is used for fixed-line (PSTN) services, and as with all geographic codes in Ukraine, it is location-dependent, meaning that the tariff and routing are based on the physical location of the subscriber's line.

Dialing Formats and Instructions

To call a fixed-line number in Kuznetsovsk/Varash from within Ukraine, subscribers must dial the trunk prefix 0, followed by the area code 3636, and then the subscriber's 5-digit local number. For example, a local number 12345 would be dialed as 0 3636 12345 from any other region in Ukraine. From abroad, callers must use the international access prefix (typically 00 or +), the country code 380, the area code 3636 (without the leading 0), and the 5-digit subscriber number: +380 3636 12345. When calling within the same area code, local calls may be made using only the 5-digit subscriber number, depending on the operator's configuration, but it is always safe to use the full national format.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 3636 area. The numbering capacity is sufficient for the region's demand. However, as with all geographic codes in Ukraine, number portability is available for fixed-line services, allowing subscribers to retain their numbers when changing operators within the same geographic area. It is important to note that the area code 3636 is distinct from the shorter code 36, which covers the larger Rivne region. Callers must use the complete 4-digit code to ensure proper routing.

Practical Guidance for Callers

For local callers within Kuznetsovsk/Varash, dialing the 5-digit local number directly may work, but for clarity and to avoid misdialing, it is recommended to use the full national format. For international callers, always replace the leading 0 with the +380 country code. Be aware that some VoIP services may require the use of the international format even for domestic calls. Always verify the number with the recipient, as the region has seen administrative changes, and some databases may still list the old name 'Kuznetsovsk'.
