Area Code 4137 – Popilnya, Zhytomyr

Overview of Area Code +380 4137

Area code +380 4137 is a geographic National Destination Code (NDC) assigned to the town of Popilnya and the surrounding Popilnia Raion in the Zhytomyr Oblast of Ukraine. This code is part of the Ukrainian public switched telephone network (PSTN) and is used for fixed-line services within this specific administrative district. The region is located in the central-northern part of Ukraine, approximately 150 kilometers southwest of the capital, Kyiv, and about 60 kilometers southeast of Zhytomyr, the oblast's administrative center.

Geographic Coverage and Administrative Jurisdiction

The +380 4137 prefix covers the urban-type settlement of Popilnya and the rural communities within the Popilnia Raion. This area is primarily agricultural, with several small villages and settlements. The code is administered by the Ukrainian national telecom regulator and is allocated to local fixed-line operators, including Ukrtelecom and alternative providers. The geographic boundaries align with the raion's administrative borders, ensuring that calls to this code terminate within the designated territory.

Dialing Formats and Caller Instructions

For callers within Ukraine, the national trunk prefix is 0. To call a number in Popilnya from another Ukrainian city, dial: 0 4137 XXX XX. For example, a local number might be 0 4137 2 45 67. For international callers, the Ukrainian country code is +380, so the same number would be dialed as +380 4137 2 45 67. When dialing locally within the same area code, the trunk prefix and area code may be omitted, but this depends on the operator's local dialing plan.

Numbering Structure and Length

Ukrainian geographic numbers typically consist of 9 digits after the country code, including the NDC. For +380 4137, the NDC is 4 digits (4137), leaving 5 digits for the subscriber number. Thus, the full international format is +380 4137 XXXXX (where X represents the subscriber digits). The subscriber number length may vary slightly depending on the operator's allocation, but the total length remains constant.

Overlay and Numbering Plan Considerations

Currently, there is no overlay code for the Popilnya area; the 4137 code is unique to this region. However, as Ukraine continues to modernize its telecom infrastructure, there is a possibility of introducing additional digits or overlays in the future. Callers should always verify the correct number with the recipient to avoid misdialing.

Practical Tips for Callers

When calling from abroad, ensure you have the correct international exit code (e.g., 00 from most European countries, 011 from North America) followed by 380 and the area code without the leading zero. For example, from the US, you would dial: 011 380 4137 2 45 67. For business or personal calls, it is advisable to store numbers in full international format to avoid confusion when traveling.
