Area Code 4734 – Chernigov region

Overview of Area Code +380 4734

Area code 4734 is a geographic National Destination Code (NDC) within the Ukrainian public switched telephone network (PSTN), allocated under the international country calling code +380 (Ukraine). This code serves a specific rural and suburban zone within the Chernihiv Oblast (Chernigov region), a northern administrative division of Ukraine bordering Belarus and the Russian Federation. The primary administrative center for this numbering area is the city of Nizhyn (Ніжин), a historic city located approximately 100 kilometers northeast of Kyiv. The 4734 code covers Nizhyn and the surrounding Nizhyn Raion (district), including smaller settlements and villages within that district.

Geographic Coverage and Jurisdiction

The 4734 numbering area falls under the jurisdiction of the Ukrainian National Commission for State Regulation of Communications and Informatization (NKRZI). It is a classic example of a geographic code, meaning that the tariff and routing of calls are based on the physical location of the fixed-line subscriber. The region is part of the Chernihiv Oblast, which is known for its agricultural production and historical significance. While the city of Chernihiv itself uses a different area code (462), the 4734 code is dedicated to the Nizhyn district, which is an important railway and highway junction.

Dialing Formats and Instructions

To call a fixed-line subscriber in the 4734 area from within Ukraine, you must use the trunk prefix 0 followed by the area code and the subscriber number. The national significant number (NSN) for this area is 9 digits long, comprising the 4-digit area code (4734) and a 5-digit local subscriber number. For example, if the local number is 12345, the national dialing format is 0 4734 12345.

For international callers, the format is +380 4734 12345 (or 00380 4734 12345 from many European countries). The leading zero of the trunk prefix is dropped when dialing from abroad. It is essential to note that Ukrainian fixed-line numbers are not portable across geographic areas; the code is tied to the physical line location.

Overlay and Numbering Considerations

As of the latest NKRZI updates, there is no overlay code for the 4734 area. Local calls within the same area code can be made using the 5-digit subscriber number alone, but this practice is becoming less common as the network modernizes. For calls from other regions of Ukraine, dial the full national format. For calls from mobile phones, the same national format is used, and callers should be aware that tariffs may vary depending on their operator and plan.

Businesses and residents in the Nizhyn area should ensure that their published numbers include the full international format to facilitate global connectivity. The Ukrainian numbering plan follows ITU-T E.164 recommendations, and this code is part of the E.164-compliant structure.
