Area Code 5239 – Ustinovka, Kirovohrad

Geographic Overview

The +380 5239 dialing prefix is a geographic National Destination Code (NDC) assigned to the fixed-line telephone network serving the town of Ustynivka (formerly Ustinovka) and its surrounding rural areas within the Kirovohrad Oblast (region) of central Ukraine. Ustynivka is the administrative center of the Ustynivka Raion (district), located approximately 60 kilometers northwest of the regional capital, Kropyvnytskyi. This numbering area falls under the jurisdiction of the Ukrainian National Commission for State Regulation of Communications and Informatization (NKRZI), which administers the national numbering plan in accordance with ITU-T E.164 recommendations.

Dialing Formats

When calling a subscriber in the Ustynivka area from within Ukraine, the trunk prefix '0' must be dialed before the area code, followed by the local subscriber number. The complete national significant number (NSN) consists of 9 digits: the NDC '5239' (4 digits) plus a 5-digit local subscriber number. For example, a local number such as 12345 would be dialed as 0 5239 12345 from any other region in Ukraine. From abroad, callers must use the international access prefix of their country (typically '00' or '+'), followed by Ukraine's country code '380', the area code '5239' without the leading '0', and the 5-digit subscriber number. Thus, an international caller would dial +380 5239 12345.

Geographic Allocation and Overlays

As a geographic code, 5239 is tied to a specific physical location and is primarily used for fixed-line PSTN services. It is not a non-geographic or mobile prefix. The code is not subject to overlay plans in the traditional sense, but the entire Kirovohrad Oblast uses a mix of area codes (e.g., 522, 5239, 5242, etc.) to serve different towns and districts. Local calls within the same area code may be dialed using only the subscriber number, depending on the operator's configuration, but the recommended format for clarity is the full national number.

Caller Instructions

• Local callers (within Ustynivka): If your operator supports abbreviated dialing, you may dial only the 5-digit subscriber number. Otherwise, use the full national format.
• National callers (from other Ukrainian cities): Dial 0 5239 [subscriber number].
• International callers: Dial your country's exit code, then 380 5239 [subscriber number] (omit the leading '0').

When roaming or using VoIP services, ensure that you use the international format to avoid misrouting. The Ukrainian numbering plan is closed, meaning that the trunk prefix '0' is used for all national calls, and the '0' is not part of the international number.
