Area Code 6243 – Great Novosilka, Donetsk

Geographic Overview

The +380 6243 dialing prefix is a geographic National Destination Code (NDC) assigned to the town of Velyka Novosilka (Велика Новосілка) and its surrounding administrative district in the Donetsk Oblast of eastern Ukraine. This code is part of the national numbering plan administered by the Ukrainian State Centre of Radio Frequencies under the framework of ITU-T E.164. The area is situated in the historical region of Donbas, near the border with Zaporizhzhia Oblast, and serves as a local administrative center.

Dialing Formats

When calling a fixed-line subscriber in this area from within Ukraine, the national trunk prefix '0' is used, followed by the NDC and the subscriber's local number. The complete national format is 0 6243 XX-XX-XX (where X represents digits of the local number, typically 5 to 7 digits). For example, a local number might be 0 6243 2-34-56.

For international callers, the Ukrainian country code +380 is used, followed by the NDC without the leading '0'. Thus, the international format becomes +380 6243 XX-XX-XX. For instance, to call a subscriber with local number 2-34-56, you would dial +380 6243 23456 from abroad.

Geographic Coverage and Jurisdiction

The 6243 code covers the settlement of Velyka Novosilka and the villages within the Velykonovosilkivska settlement hromada. This includes localities such as Novosilka, Oleksandrivka, and other nearby settlements. The area is part of the Donetsk administrative region, although due to the ongoing conflict in eastern Ukraine, service availability and network infrastructure may be affected. The code is used for fixed-line PSTN services, including traditional copper lines and some VoIP-based fixed services.

Overlays and Numbering

As of the latest update, there is no overlay code for this area; the 6243 code is the sole geographic NDC for this locality. Subscriber numbers within this code typically have a length of 5 to 7 digits, resulting in a total national significant number (NSN) length of 9 to 11 digits when including the NDC. The exact number length may vary depending on the operator and the specific exchange.

Caller Instructions

• Local callers within the same area: If you are calling from another fixed-line number within the 6243 area, you may be able to dial only the local subscriber number without the trunk prefix and area code, depending on your operator's local dialing plan. However, for clarity and consistency, it is recommended to use the full national format.
• National callers from other regions of Ukraine: Dial 0 6243 followed by the subscriber's number.
• International callers: Dial your country's international access code (e.g., 00 from most European countries, 011 from the US/Canada), then 380 6243 and the subscriber's number.

Given the dynamic situation in the Donetsk region, it is advisable to verify the current status of the number and network availability with your service provider or the relevant Ukrainian authorities.
