Area Code 5531 – Ivanivka, Kherson

Geographic Overview

The area code +380 5531 is a geographic National Destination Code (NDC) assigned to the town of Ivanivka and its surrounding rural districts within the Kherson Oblast of southern Ukraine. This code is part of the national numbering plan administered by the Ukrainian State Centre of Radio Frequencies (UCRF) under the framework of ITU-T E.164. Ivanivka serves as the administrative center of the Ivanivka Raion, a primarily agricultural region located approximately 100 kilometers northeast of the city of Kherson. The geographic coverage includes the town itself and nearby villages, with fixed-line services provided by local operators, including Ukrtelecom and alternative carriers that have deployed local loop infrastructure.

Dialing Formats

When calling an Ivanivka fixed-line number from within Ukraine, subscribers must use the trunk prefix 0 followed by the area code and the subscriber number. For example, a local number might be dialed as 0 5531 2 34 56. From abroad, callers must use the Ukrainian country code +380, the area code without the leading zero, and the subscriber number, resulting in the international format +380 5531 2 34 56. The subscriber number length in this area typically ranges from five to seven digits, depending on the capacity of the local exchange and the operator's allocation.

Caller Guidance

For callers within Ukraine, it is essential to include the trunk prefix 0 before the area code when dialing from a different region or from a mobile phone. Failure to do so will result in an incomplete call. International callers should be aware that the leading zero is not dialed after the country code. Additionally, while most fixed-line services in Ukraine are interconnected via the PSTN, some operators may route calls over IP networks, but the dialing format remains unchanged. As with all geographic codes, the number is tied to a physical location, and calls are charged based on the distance and the operator's tariff plan.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Ivanivka area, meaning that the 5531 code is the sole geographic code for this region. However, subscribers may have the option to port their numbers to other operators within the same geographic area, in accordance with the national number portability regulations. It is also worth noting that due to the ongoing conflict in the region, service availability may be intermittent, and some lines may be temporarily out of service. For the most accurate and up-to-date information, users are advised to consult their service provider.
