Area Code 5131 – Bratsk, Mykolayiv

Geographic Overview

The +380 5131 dialing prefix is a geographic National Destination Code (NDC) assigned to the town of Bratsk and its surrounding rural areas within the Mykolayiv Oblast (province) of southern Ukraine. This code is part of the national numbering plan administered by the Ukrainian State Centre of Radio Frequencies (UCRF) under the framework of ITU-T Recommendation E.164. The geographic area served by this prefix is characterized by agricultural communities and small settlements, with Bratsk serving as the primary administrative center. The region is located along the Southern Bug River, approximately 120 kilometers northwest of the regional capital, Mykolayiv.

Dialing Formats

For callers within Ukraine, the national trunk prefix '0' is used before the area code. To reach a subscriber in Bratsk from another Ukrainian city, dial: 0 5131 XXX XX (where X represents the local subscriber number). For international callers, the Ukrainian country code +380 is used, followed by the area code without the leading '0', resulting in: +380 5131 XXX XX. For example, a local number 2 34 56 would be dialed as 0 5131 2 34 56 domestically and as +380 5131 2 34 56 from abroad.

Numbering and Subscriber Numbers

Subscriber numbers within the 5131 area code typically consist of 5 to 7 digits, depending on the specific exchange and historical allocation. The total length of a national significant number (NSN) for Ukrainian geographic numbers is 9 digits, which includes the area code (without the trunk prefix) and the subscriber number. Therefore, for the 5131 code, the subscriber number length is 5 digits (since 5131 is a 4-digit code, 9 - 4 = 5). However, some rural exchanges may have shorter subscriber numbers, but the NSN remains 9 digits by padding with leading zeros if necessary. It is important to note that the Ukrainian numbering plan does not currently use overlay codes for this region; the 5131 code is unique to Bratsk and its vicinity.

Caller Instructions

Local callers within Bratsk may be able to dial only the 5-digit subscriber number without the area code, depending on the local exchange configuration. However, for reliability, it is recommended to always use the full national format. Callers from other regions of Ukraine must dial the trunk prefix '0' followed by the area code and subscriber number. International callers should replace the trunk prefix with the +380 country code. For example, a caller from the United States would dial 011 380 5131 XXX XX, while a caller from the United Kingdom would dial 00 380 5131 XXX XX.

Technical Considerations

All geographic numbers in Ukraine are subject to number portability, meaning that a subscriber may retain their number when switching between fixed-line operators, but the geographic significance of the number may remain tied to the original location. Calls to this prefix are routed over the PSTN and may be carried over IP networks using VoIP gateways, but the tariff structure typically reflects the geographic destination. Emergency services are reached via the national numbers 101 (fire), 102 (police), 103 (ambulance), and 112 (general emergency), which are independent of geographic area codes.
