Area Code 4139 – Chudniv, Zhytomyr

Geographic Overview

The area code +380 4139 is a geographic National Destination Code (NDC) assigned to the town of Chudniv and its surrounding rural districts within the Zhytomyr Oblast of Ukraine. Chudniv is situated on the banks of the Teteriv River, approximately 60 kilometers southwest of Zhytomyr, the regional capital. The code serves a predominantly residential and agricultural area, with local administrative and business services concentrated in the town center.

Dialing Formats

For callers within Ukraine, the national trunk prefix 0 must be dialed before the area code. The complete national format is 0 4139 XX XX, where the subscriber number consists of five digits following the area code. For example, a local number in Chudniv might be formatted as 0 4139 2 34 56.

International callers must replace the trunk prefix with Ukraine's country calling code +380, resulting in the format +380 4139 XX XX. Thus, the same number would be dialed as +380 4139 2 34 56 from abroad. When dialing internationally, the leading zero of the trunk prefix is omitted.

Caller Instructions

• Local callers (within Chudniv): For calls to another subscriber within the same area code, local dialing may be possible using only the five-digit subscriber number, depending on the operator's network configuration. However, it is safer to use the full national format to ensure connectivity.
• National callers (outside Chudniv): Dial 0 4139 followed by the five-digit subscriber number. For example, to call a number in Chudniv from Kyiv, dial 0 4139 2 34 56.
• International callers: Dial your country's exit code (e.g., 00 from most European countries, 011 from the US/Canada), then 380 4139 followed by the five-digit subscriber number. For instance, from the UK, you would dial 00 380 4139 2 34 56.

Numbering Plan Considerations

As of the latest ITU-T E.164 national numbering plan for Ukraine, the NDC 4139 is a geographic code with a fixed subscriber number length of five digits, making the total national significant number (NSN) length nine digits (including the trunk prefix). No overlay codes have been implemented for Chudniv, so the area code is not shared with other localities. The code is administered by the Ukrainian State Centre of Radio Frequencies (UCRF) under the jurisdiction of the National Commission for State Regulation of Electronic Communications, Informatization and Informatization (NCEC).

It is important to note that while geographic codes traditionally correspond to fixed-line services, some operators may use them for VoIP-based fixed services, but the geographic association remains for routing and tariff purposes. Callers should verify the correct number with the recipient, as number portability within Ukraine allows subscribers to retain their numbers when changing operators, but geographic numbers are generally tied to the original location.
