Area Code 6266 – Kramatorsk/Slavyansk, Donetsk

Geographic Coverage and Administrative Jurisdiction

The Ukrainian national destination code 6266 is a geographic area code assigned to the urban agglomeration of Kramatorsk and Slovyansk in the northern part of Donetsk Oblast. This region functions as a key administrative and industrial hub, especially since the temporary relocation of the Donetsk Oblast administration to Kramatorsk in 2014. The code covers the city territories of Kramatorsk, Slovyansk, and their immediate suburban zones, including Druzhkivka and the surrounding settlements. As a geographic code, 6266 is used exclusively for fixed-line PSTN services within this defined area.

Dialing Formats and Number Structure

When calling a subscriber in the Kramatorsk/Slovyansk zone, the national significant number (NSN) comprises the trunk prefix 0, the area code 6266, and a local subscriber number of either 5 or 6 digits, depending on the specific exchange. For example, a typical local number might be 5-12-34, resulting in the national format 0 6266 5-12-34. From abroad, callers must use the international prefix (00 or +) followed by Ukraine's country code 380, then the area code without the leading zero: +380 6266 5-12-34. Within the same local area, callers can often dial the subscriber number directly without the trunk prefix and area code, but this practice is being phased out in favor of full national dialing in many regions.

Overlay and Numbering Plan Considerations

Currently, there is no overlay code for the 6266 area. However, due to the ongoing conflict and administrative changes, the Ukrainian regulator (NCCIR) has implemented measures to ensure numbering resource flexibility. In some cases, numbers from this code may be reassigned or ported to other regions for displaced subscribers, but the geographic significance remains. For callers, it is essential to note that mobile numbers in Ukraine always begin with 0 6X (e.g., 067, 068, 099) and are non-geographic; thus, 6266 is exclusively for fixed lines.

Caller Instructions

For local callers: If you are within the Kramatorsk/Slovyansk zone, you may dial the 5- or 6-digit subscriber number directly. However, for clarity and to avoid errors, it is recommended to dial the full national format 0 6266 [subscriber number].

For national callers (outside the area): Dial 0 6266 [subscriber number]. For example, to call a business in Kramatorsk with the number 5-12-34, dial 0 6266 5-12-34.

For international callers: Replace the leading 0 with the country code 380, so the number becomes +380 6266 5-12-34. Ensure you use the correct international exit code from your country (e.g., 011 from the US, 00 from most European countries).
