Area Code 6137 – Primorsk, Zaporizhzhia

Geographic Overview

The +380 6137 dialing prefix is a geographic National Destination Code (NDC) assigned to the town of Primorsk (formerly known as Nakhodka) and its surrounding administrative district within the Zaporizhzhia Oblast of Ukraine. This area is situated in the southeastern part of the country, near the northern coast of the Sea of Azov. The code serves the fixed-line telephone network, connecting subscribers within the Primorsk urban hromada and adjacent rural settlements.

Dialing Format

When calling a landline in Primorsk from within Ukraine, the national trunk prefix 0 is dialed before the area code, followed by the subscriber's local number. The complete national format is 0 6137 XX-XX-XX, where the local number typically consists of 5 to 7 digits. For international callers, the Ukrainian country code +380 replaces the trunk prefix, resulting in the format +380 6137 XX-XX-XX. For example, a local number 5-43-21 would be dialed as 0 6137 5-43-21 domestically and +380 6137 5-43-21 from abroad.

Jurisdictional and Administrative Notes

Primorsk serves as the administrative center of the Primorsk Raion (district). The geographic coverage of the 6137 code is limited to this district, which includes the town itself and nearby villages. As part of the Zaporizhzhia region, the area is under the jurisdiction of the Zaporizhzhia Oblast Council. The code is allocated to the national operator Ukrtelecom and other licensed fixed-line providers, ensuring PSTN connectivity.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Primorsk area; the 6137 prefix remains the sole geographic code for this locality. All fixed-line numbers within the district share this prefix. Subscribers cannot port their fixed-line numbers to mobile networks, as number portability applies only within the same service category. For VoIP or mobile calls, the geographic nature of the code does not affect routing; calls are terminated on the PSTN.

Caller Instructions

• Local callers within Primorsk may sometimes omit the area code if the call is within the same exchange, but it is recommended to always dial the full national number to avoid misrouting.
• Domestic callers from other Ukrainian cities must dial 0 6137 followed by the subscriber number.
• International callers should dial their international access code (e.g., 00 from most countries) or the plus sign (+), then 380 6137 and the subscriber number.

For accurate billing and routing, always confirm the subscriber number length, as it may vary. The code is part of the Ukrainian numbering plan under the National Commission for State Regulation of Communications and Informatization.
