Area Code 5257 – Bobrinets, Kirovohrad

Geographic Overview

The +380 5257 dialing prefix is a geographic National Destination Code (NDC) assigned to the fixed-line telephone network of Bobrynets (also transliterated as Bobrinets), a city in the Kirovohrad Oblast of central Ukraine. This code is part of the national numbering plan administered by the Ukrainian State Centre of Radio Frequencies under the framework of ITU-T E.164. The geographic service area covers the city itself and the surrounding administrative district, including smaller settlements and rural communities that fall under the Bobrynets territorial hromada. As a fixed-line code, it is primarily used for PSTN (Public Switched Telephone Network) services, though some local operators may provide VoIP-based fixed telephony using the same geographic prefix.

Dialing Formats and Procedures

For domestic callers within Ukraine, the number is dialed in the national format: 0 5257 XXX XX (where X represents the subscriber's local number). The leading '0' is the trunk prefix used to access the national long-distance network. For example, to call a Bobrynets landline from Kyiv, one would dial 0 5257 12345 (assuming a 5-digit subscriber number). For international callers, the number must be dialed in the full international format: +380 5257 XXX XX, omitting the trunk prefix '0'. For instance, a caller from the United States would dial 011 380 5257 12345, while a caller from the United Kingdom would dial 00 380 5257 12345. It is crucial to note that the subscriber number length within the 5257 area may vary; some numbers may have 5 or 6 digits, but the total length of the national significant number (NSN) after the trunk prefix is always 9 digits (excluding the leading 0).

Geographic Significance and Overlays

Bobrynets is a small administrative center with a population of around 10,000. The 5257 code is one of several geographic codes in the Kirovohrad region, which also includes the regional capital Kropyvnytskyi (code 522) and other district centers. There are currently no overlay codes or number portability issues affecting the geographic assignment; the code remains tied to the physical location of the fixed-line exchange. However, as with all Ukrainian fixed-line numbers, subscribers may request number portability to another operator within the same geographic area, but the prefix does not change.

Caller Instructions

Local callers within the Bobrynets area can often dial the subscriber number directly without the trunk prefix, depending on the local network configuration. However, for clarity and consistency, it is recommended to always use the full national format. For foreign callers, it is essential to replace the '+' with the appropriate international access code from their country. Additionally, be aware that calls to Ukrainian fixed-line numbers are typically charged at standard international rates, which vary by provider. VoIP users should ensure they are using the correct exit code and country code to avoid misdialing.
