Area Code 4564 – Stavyshche, Kyiv

Geographic Overview

The +380 4564 prefix is a geographic National Destination Code (NDC) assigned to the fixed-line telephone network of Stavyshche, an urban-type settlement in the Bila Tserkva Raion of Kyiv Oblast, Ukraine. Stavyshche serves as the administrative center of the Stavyshche settlement hromada and is located approximately 90 kilometers southwest of Kyiv, the national capital. This code is part of the national numbering plan administered by the Ukrainian State Centre of Radio Frequencies (UCRF) under the authority of the National Commission for State Regulation of Electronic Communications, Informatisation and Information Society (NCCIR).

Technical Allocation and Dialing Procedures

The prefix 4564 is a geographic code, meaning that the tariff and routing are based on the physical location of the subscriber line. Subscriber numbers within this code typically have a total length of 9 digits when dialed in international format, including the trunk prefix and area code. The structure is: +380 (country code) 4564 (NDC) followed by a local subscriber number of 5 to 7 digits, depending on the capacity of the local exchange.

For callers within Ukraine, the international prefix is replaced by the trunk prefix '0'. Thus, a local call to Stavyshche from another region of Ukraine would be dialed as 0 4564 XX XX XX. For example, a local number might be dialed as 0 4564 2 34 56. For international callers, the full international format is +380 4564 XX XX XX (e.g., +380 4564 2 34 56).

It is important to note that Ukraine has implemented a uniform dialing plan since 2009, requiring the use of the trunk prefix '0' for all domestic calls, including local calls within the same area code. However, within the Stavyshche local area, shorter dialing may be possible for calls between exchanges in the same local network, but this is not guaranteed for all subscribers, especially with the migration to Next Generation Networks (NGN).

Overlay and Numbering Considerations

As of the latest available data, there is no overlay code for the 4564 area. The code is exclusively assigned to fixed-line services, and no mobile or VoIP services are directly associated with this geographic prefix. Mobile numbers in Ukraine are identified by non-geographic codes beginning with 50, 63, 66, 67, 68, 73, 91, 92, 93, 94, 95, 96, 97, 98, and 99. Therefore, a caller should not confuse the 4564 prefix with a mobile number.

For businesses and residents in Stavyshche, the use of the +380 4564 code is mandatory for all fixed-line connections. When calling from abroad, it is essential to use the international format without the leading '0'. For example, a caller from the United States would dial 011 380 4564 2 34 56, while a caller from the United Kingdom would dial 00 380 4564 2 34 56.

In the context of number portability, fixed-line numbers in Ukraine are portable within the same geographic area. This means that a subscriber may retain their +380 4564 number when switching between fixed-line operators, provided the new operator offers service in the Stavyshche area. However, the geographic significance of the code remains, and the number cannot be moved to a different region.
