Area Code 4331 – Bratslav/Nemyriv, Vinnytsia

Geographic Coverage and Administrative Jurisdiction

The Ukrainian national destination code (NDC) 4331 is a geographic area code assigned to the Bratslav and Nemyriv districts within the Vinnytsia Oblast (province) of Ukraine. This code falls under the broader Vinnytsia numbering plan area, which is administered by the Ukrainian State Centre of Radio Frequencies (UCRF) in accordance with the national numbering plan and ITU-T E.164 recommendations. The region is located in the historic Podolia area, approximately 65 kilometers southeast of the city of Vinnytsia. The code serves both the urban administrative centers of Nemyriv and the smaller town of Bratslav, along with the surrounding rural settlements.

Dialing Formats and Number Structure

Within Ukraine, calls to a subscriber in the 4331 area require trunk prefix 0 followed by the area code and the subscriber's local number. The complete national significant number (NSN) length is 9 digits, comprising the area code (4 digits) and a 5-digit subscriber number. For example, a local number such as 2-34-56 would be dialed as 0-4331-2-34-56 from other regions of Ukraine. From abroad, callers must use the international access prefix (typically 00 or +), followed by Ukraine's country code 380, then the area code without the leading trunk prefix, and the subscriber number. The international format for the same example would be +380 4331 2 34 56.

Local and International Caller Instructions

Local callers within the Bratslav/Nemyriv area may often dial the 5-digit subscriber number directly without the area code, depending on the specific local exchange configuration. However, for clarity and to avoid misdialing, it is recommended to always use the full national format (0-4331-XXXXX) when calling from a mobile phone or from outside the immediate local area. Foreign callers should note that the leading '0' of the trunk prefix is not included when dialing from abroad. Additionally, when storing numbers in international format, it is standard practice to replace the trunk prefix with the '+' sign, as in +380 4331 XXXXX.

Overlay and Numbering Plan Considerations

As of the current numbering plan, there is no overlay code for the 4331 area. The Vinnytsia region has multiple geographic codes, and 4331 is distinct from the regional capital's code (432). This means that calls between different codes within the Vinnytsia Oblast require the full national dialing format. The Ukrainian regulator has implemented number portability for fixed lines, allowing subscribers to retain their numbers when changing operators within the same geographic area, but the geographic significance of the code remains unchanged. For VoIP and IP-based services, users may be assigned numbers from this code, but the service is not tied to a physical location, which is an important consideration for emergency services and caller location identification.
