Area Code 5136 – Yuzhnoukrainsk, Mykolayiv

Geographic Overview

The +380 5136 prefix is a geographic National Destination Code (NDC) assigned to the city of Yuzhnoukrainsk and its surrounding areas within the Mykolayiv Oblast of Ukraine. Yuzhnoukrainsk is a relatively modern city, established in the 1970s to support the South Ukraine Nuclear Power Plant, and is located along the Southern Bug River. The code serves the city's fixed-line telephone network, including residential, business, and government lines.

Dialing Formats

When calling a Yuzhnoukrainsk number from within Ukraine, subscribers must dial the national trunk prefix 0, followed by the area code 5136 and the subscriber's 5-digit local number. The complete national format is: 0 5136 XX XX XX (where X represents the local digits). For example, a local number might be dialed as 0 5136 2 34 56.

For international callers, the Ukrainian country code +380 replaces the trunk prefix, and the leading zero of the area code is omitted. The international dialing format is: +380 5136 XX XX XX. For instance, a caller from abroad would dial +380 5136 2 34 56 to reach the same subscriber.

Geographic and Administrative Context

Yuzhnoukrainsk is an administrative center of the Yuzhnoukrainsk city council, which has a special status within the Mykolayiv Oblast. The area code 5136 is part of the national numbering plan of Ukraine, which follows ITU-T E.164 recommendations. The code is geographic, meaning it is tied to a specific physical location and is primarily used for PSTN (Public Switched Telephone Network) services. However, with the advent of VoIP and number portability, some subscribers may have their numbers routed over IP networks, but the geographic association remains for regulatory and emergency services purposes.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for Yuzhnoukrainsk; the 5136 code serves the city exclusively. The local numbering capacity is sufficient for the population, which is around 40,000. Subscribers in Yuzhnoukrainsk can call other Ukrainian cities by dialing the trunk prefix 0, the respective area code, and the local number. For calls to mobile phones, the same procedure applies, using the mobile network prefixes (e.g., 067, 095, etc.).

Caller Instructions

Local callers within Yuzhnoukrainsk can dial the 5-digit subscriber number directly without the area code, as per Ukrainian dialing rules. However, for clarity and to avoid errors, it is recommended to use the full national format. Foreign callers should always use the international format +380 5136 followed by the local number. It is important to note that when dialing from a mobile phone, the plus sign (+) may be replaced by the international access code of the country from which the call is placed (e.g., 011 from the US, 00 from most European countries).
