Area Code 6255 – Shakhtarsk, Donetsk

Geographic Overview

The +380 6255 area code is a geographic National Destination Code (NDC) assigned to the city of Shakhtarsk and its surrounding administrative district in the Donetsk Oblast of eastern Ukraine. This region falls within the historic Donbas coal-mining basin, and Shakhtarsk itself is a mid-sized industrial city. The code is used for fixed-line PSTN services within this specific locality, and it is not associated with mobile or nomadic services.

Dialing Formats

For callers within Ukraine, the national trunk prefix '0' is used before the area code. Thus, a local number in Shakhtarsk would be dialed as 0 6255 XXX XX (where X represents the subscriber's 5-digit line number). The full national number is 9 digits long (excluding the trunk prefix). For international callers, the Ukrainian country code +380 is used, and the trunk prefix is omitted. The international format becomes +380 6255 XXX XX. For example, a typical number might be +380 6255 12345.

Geographic Coverage and Administration

The 6255 code specifically serves the city of Shakhtarsk and the adjacent settlements within the Shakhtarsk Raion (district). It is important to note that due to the ongoing conflict in the Donetsk region, some areas may experience service disruptions or may be served by alternative providers. However, the code remains officially assigned to this geographic area under the National Commission for State Regulation of Communications and Informatization (NCCIR) of Ukraine.

Caller Instructions

• Local callers (within Ukraine): Dial 0 6255 XXX XX from any fixed or mobile phone. If you are calling from a mobile phone, you may also use the international format +380 6255 XXX XX, but the national format is standard.
• International callers: Dial your country's exit code (e.g., 00 from most European countries, 011 from the US/Canada), followed by 380 6255 XXX XX. Do not include the leading '0' of the national trunk prefix.

Numbering Plan Considerations

As of the latest ITU-T E.164 allocation, Ukraine's numbering plan uses a closed dialing plan for fixed lines, meaning that the full national number (including the area code) must be dialed even for local calls. There is no overlay code for Shakhtarsk; the 6255 code is exclusive to this area. Subscriber numbers within this code are 5 digits long, making the total length of a national significant number (NSN) 9 digits, which is standard for Ukrainian geographic codes.

For businesses or individuals in Shakhtarsk, it is crucial to ensure that their numbers are correctly listed in international directories with the +380 6255 prefix to avoid routing errors. When dialing from abroad, always verify the current status of the region, as some areas may be temporarily unreachable due to infrastructure damage.
