Area Code 4134 – Chernyakhov, Zhytomyr

Overview of Area Code +380 4134

Area code +380 4134 is a geographic destination code within the Ukrainian national numbering plan, assigned to the town of Chernyakhov and the surrounding Chernyakhiv Raion in Zhytomyr Oblast. This code follows the ITU-T E.164 international dialing standard and is used for routing calls to fixed-line (PSTN) subscribers within this administrative district. The Zhytomyr region is located in the north-central part of Ukraine, and Chernyakhov serves as the administrative center of the raion.

Geographic Coverage and Administrative Jurisdiction

The +380 4134 code covers Chernyakhov and the settlements under the jurisdiction of the Chernyakhiv Raion. This includes villages and smaller communities that are part of the raion's administrative structure. The code is managed by the Ukrainian State Enterprise of Communications (Ukrtelecom) and other licensed fixed-line operators that provide services in the area. As a geographic code, it is tied to the physical location of the subscriber's line, and call routing is based on the destination's location.

Dialing Formats and Instructions

To call a fixed-line number in Chernyakhov from within Ukraine, subscribers must dial the trunk prefix 0, followed by the area code 4134 and the subscriber's local number. The local number length in this area is typically 5 digits, resulting in a total national significant number length of 9 digits (excluding the trunk prefix). For example, a local number might be 2-34-56, and the national dialing format would be 0 4134 2-34-56.

For international callers, the country code for Ukraine is +380, so the full international dialing format becomes +380 4134 2-34-56. When dialing from a mobile phone, the same international format is used, and the leading zero of the national prefix is omitted. It is essential to include the area code even when calling from a mobile phone within Ukraine, as the national numbering plan requires it for all geographic numbers.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Chernyakhov area, meaning that the +380 4134 code is the only geographic code assigned to this region. However, subscribers should be aware that number portability exists in Ukraine, allowing users to retain their numbers when switching between fixed-line operators, but the geographic code remains tied to the original location. For VoIP and mobile users, the geographic code is not used; instead, non-geographic mobile prefixes (e.g., +380 67, +380 95) are assigned.

Caller Instructions

Local callers within the Chernyakhov area may be able to dial only the local number without the area code if they are within the same local calling area, but this is not guaranteed and depends on the operator's configuration. To avoid confusion, it is recommended to always use the full national format. Foreign callers should replace the leading zero with the +380 country code and ensure they have the correct international exit code for their country (e.g., 00 from most European countries, 011 from North America).
