Area Code 6265 – Kramatorsk/Slavyansk, Donetsk

Geographic Coverage and Administrative Jurisdiction

The Ukrainian national destination code 6265 is a geographic area code assigned to the eastern Donetsk Oblast, specifically serving the urban agglomerations of Kramatorsk and Slovyansk, along with adjacent settlements. These cities function as major administrative and industrial centers within the region. As a geographic code, 6265 routes calls to fixed-line PSTN subscribers whose physical lines are terminated within this designated exchange area.

Dialing Formats and Number Structure

Within Ukraine, calls to numbers in the 6265 area require trunk prefix 0 followed by the area code and the subscriber's local number. The complete national significant number (NSN) for a Kramatorsk or Slovyansk fixed line typically consists of 9 digits after the trunk prefix, formatted as 0 6265 XX-XX-XX (where X represents the local subscriber digits). For international callers, the country calling code +380 replaces the trunk prefix, yielding the format +380 6265 XX-XX-XX. For example, a local Kramatorsk number might be dialed as 0 6265 45-67-89 domestically, while callers from abroad would dial +380 6265 45-67-89.

Overlay Considerations and Numbering Plan Evolution

Currently, the 6265 area code does not have an overlay code, meaning that all fixed-line numbers within the Kramatorsk/Slovyansk zone share the same area code. However, as with many regions in Ukraine, the national numbering plan is subject to periodic review by the Ukrainian State Centre of Radio Frequencies (UCRF). Subscribers and businesses should be aware that local calls within the same area code may still require the full 9-digit number (including area code) depending on the operator's dialing plan. It is always advisable to confirm the correct dialing procedure with your service provider.

Caller Instructions

• Local callers (within Ukraine): Dial 0 6265 followed by the subscriber's 7-digit local number. For example, to call a business in Kramatorsk, dial 0 6265 12-34-56.
• International callers: Dial your country's international access code (e.g., 011 from the US, 00 from most European countries), then 380, then 6265, and the local number. For instance, from the UK, dial 00 380 6265 12-34-56.

Important Notes for Businesses and Residents

Due to the ongoing geopolitical situation in the Donetsk region, telecommunications infrastructure may be subject to service interruptions or rerouting. Fixed-line services in the area are provided by Ukrtelecom and alternative operators, but availability can vary. For VoIP or mobile calls, routing to 6265 numbers is handled through the national PSTN, and call quality may depend on the current network status. Always verify the current dialing procedures and service availability with your telecom operator, especially for critical communications.
