Administratively, Dokuchaevsk falls under the jurisdiction of the Donetsk regional administration, although due to the ongoing conflict in the region, the actual provision of telecommunication services may be subject to changes. The area code 6275 is part of the national numbering plan of Ukraine, which follows the ITU-T E.164 recommendation. Within Ukraine, the trunk prefix is '0', so calls from within the country to Dokuchaevsk are dialed as 0 6275 XXX XXX.

Technical Considerations

From a technical standpoint, the +380 6275 prefix is allocated for fixed-line services, primarily provided by the national incumbent operator Ukrtelecom, as well as alternative fixed-line operators that may have local presence. The network supports traditional PSTN services, and in recent years, VoIP services have been integrated, allowing for IP-based calls to these numbers. When routing calls to Dokuchaevsk, international carriers must ensure that the call is correctly routed via the Ukrainian national network, which may involve transit through major switching centers in Kyiv or Donetsk. For accurate billing and routing, it is essential to use the correct country code and area code.
