Geographic Overview

The +380 6272 prefix is a geographic National Destination Code (NDC) assigned to the fixed-line telephone network serving Kostiantynivka, a city in the Donetsk Oblast of eastern Ukraine.

Kostiantynivka is an important industrial center, known for its metallurgical and glass production, and lies approximately 45 kilometers north of Donetsk city. The geographic area covered by this prefix includes the city itself and the surrounding rural settlements within the Kostiantynivka Raion (district).

Dialing Formats

When calling a fixed-line subscriber in Kostiantynivka from within Ukraine, the national trunk prefix '0' is used, followed by the NDC '6272' and the subscriber's 5-digit local number. The complete national format is: 0 6272 XX XX XX. For example, a local number might be dialed as 0 6272 3 45 67.

For international callers, the Ukrainian country code '+380' replaces the trunk prefix, and the NDC is used without the leading '0'. The international format is: +380 6272 XX XX XX. Thus, the same number would be dialed as +380 6272 3 45 67 from abroad.

Caller Instructions

Local callers within Kostiantynivka may be able to dial the 5-digit subscriber number directly without the area code, depending on the local network configuration. However, for clarity and consistency, it is recommended to always use the full national format. Callers from other Ukrainian cities must dial the trunk prefix '0' and the area code '6272' before the local number. International callers must use their country's international exit code (e.g., '00' in most European countries, '011' in North America) followed by Ukraine's country code '380' and the area code '6272' (without the leading '0').

Regulatory and Technical Notes

The Ukrainian numbering plan is administered by the Ukrainian State Centre of Radio Frequencies (UCRF) under the Ministry of Digital Transformation. Geographic numbers like those under 6272 are tied to a physical location and are typically used for fixed-line PSTN services. As of recent years, number portability is available for fixed-line services within Ukraine, allowing subscribers to retain their numbers when changing operators, but the geographic significance remains. Due to the ongoing conflict in the Donetsk region, some fixed-line infrastructure may be disrupted; however, the numbering plan remains officially assigned. For VoIP or mobile alternatives, callers should be aware that routing may differ, and it is advisable to verify the current status of the line with the service provider.
