Area Code 6139 – Energodar, Zaporizhzhia

Overview of Area Code +380 6139

Area code +380 6139 is a geographic destination code within the Ukrainian national numbering plan, assigned to the city of Energodar and its surrounding settlements in the Zaporizhzhia Oblast (region) of southeastern Ukraine. Energodar is situated on the left bank of the Dnipro River and is internationally known as the location of the Zaporizhzhia Nuclear Power Plant. The code is part of the national destination code (NDC) block 61, which serves the broader Zaporizhzhia region, with the additional digits '39' identifying the specific local exchange area.

Geographic Coverage and Administrative Jurisdiction

The +380 6139 prefix covers the administrative territory of the city of Energodar, including its industrial zones and residential districts. As a geographic number, it is tied to the physical location of the subscriber's line, typically delivered over the public switched telephone network (PSTN) or fixed VoIP services registered to that area. The code is administered by the Ukrainian State Enterprise of Communications (Ukrtelecom) under the authority of the National Commission for State Regulation of Communications and Informatization (NCCIR).

Dialing Formats and Caller Instructions

To call a landline in Energodar, callers must use the appropriate international or national dialing format. For international callers, the full international format is +380 6139 XXX XX (where X represents the subscriber's local number digits). For example, a local number might be dialed as +380 6139 12345 from abroad. Within Ukraine, callers must dial the national trunk prefix '0' followed by the area code and the subscriber number: 0 6139 XXX XX. For instance, a domestic call would be placed as 0 6139 12345. Local calls within the same exchange area may be made using only the subscriber number, but this practice is becoming less common with modern telephony.

Overlay and Numbering Considerations

Currently, there is no overlay code for the 6139 area; the numbering plan remains a single-code system. However, due to the ongoing conflict in the region, service availability may be affected, and call routing could be subject to temporary changes. Subscribers in Energodar may have fixed-line services provided by Ukrtelecom or alternative operators, but the geographic prefix remains a key identifier for routing calls to the correct local exchange.

Important Notes for Callers

When calling from a mobile phone within Ukraine, the national format (0 6139 ...) is used. For international callers, the plus sign (+) represents the international access code (00 in most countries), so the full number is +380 6139 .... Always verify the current status of the region before placing calls, as network infrastructure may be impacted by local conditions.
