Area Code 4131 – Chervonoarmiysk, Zhytomyr

Geographic Overview

The +380 4131 dialing prefix is a geographic National Destination Code (NDC) assigned to the Chervonoarmiysk (formerly known as Chervonoarmiysk, now often referred to as Chervona Army) area within the Zhytomyr Oblast of Ukraine. This code serves the administrative district centered on the town of Chervonoarmiysk, which is located in the northern part of the country. The region is primarily rural, with the town acting as a local administrative and commercial hub. The geographic coverage of this prefix includes the town itself and the surrounding villages and settlements within the district.

Dialing Formats

For callers within Ukraine, the local dialing format for numbers in the Chervonoarmiysk area is 0 4131 XXX XX (where X represents the subscriber number digits). The leading '0' is the trunk prefix used for domestic calls. When dialing from abroad, the international format is +380 4131 XXX XX or +380 4131 XXX XX (the leading '0' is omitted, and the country code +380 is used). For example, a local number might be 0 4131 234 56, which would be dialed as +380 4131 234 56 from outside Ukraine.

Numbering Structure

Under the ITU-T E.164 standard, the full international number consists of the country code +380, the NDC 4131, and a subscriber number of variable length. In the Chervonoarmiysk area, subscriber numbers typically consist of 5 to 6 digits, resulting in a total national significant number length of 9 to 10 digits. This prefix is a geographic allocation, meaning that the number is tied to a physical line in the local PSTN (Public Switched Telephone Network).

Overlay and Regulatory Considerations

As of the latest available data, there is no overlay code for this area, and the 4131 prefix is the sole geographic code for the Chervonoarmiysk district. The National Commission for State Regulation of Communications and Informatization (NCCIR) oversees the allocation of numbering resources in Ukraine. In recent years, the Ukrainian telecommunications market has seen a gradual migration towards IP-based telephony, but traditional PSTN services remain operational. Callers should note that when dialing from a mobile phone, the same international format applies, and roaming charges may apply if the caller is outside Ukraine.

Caller Instructions

For local callers within the same area code, it is possible to dial only the subscriber number without the trunk prefix and area code, depending on the local network configuration. However, for clarity and to avoid misdialing, it is recommended to always use the full national format (0 4131 XXX XX) when calling from other regions of Ukraine. International callers should replace the leading '0' with the +380 country code. It is also important to verify the current number length, as the Ukrainian numbering plan has undergone changes in the past to accommodate the growing demand for telecommunication services.
