Area Code 4571 – Vasilkov/Glevaha/Grebinky/Kalinovka, Kyiv

Overview of Area Code +380 4571

Area code +380 4571 is a geographic destination code within the Ukrainian national numbering plan, conforming to ITU-T E.164 recommendations. It serves a cluster of towns and settlements in the Kyiv Oblast (Kyiv Region) of central Ukraine, specifically the localities of Vasylkiv, Hlevakha, Hrebinky, and Kalynivka. These communities are situated in the southern part of the oblast, within the broader Kyiv metropolitan area's commuter belt. The code is assigned to fixed-line PSTN (Public Switched Telephone Network) services and is administered by the Ukrainian State Enterprise of Communications (Ukrposhta is not involved; the regulator is the National Commission for State Regulation of Communications and Informatization).

Geographic Coverage and Administrative Context

The primary city associated with this code is Vasylkiv, an ancient city located approximately 30 kilometers south of Kyiv's city center. Vasylkiv serves as the administrative center of the Vasylkiv Raion (district). The other localities—Hlevakha, Hrebinky, and Kalynivka—are smaller urban-type settlements and villages within the same district. This area is characterized by a mix of residential suburbs, industrial zones, and agricultural land. The code covers a contiguous geographic area, and subscribers within this zone share the same local dialing area.

Dialing Formats and Caller Instructions

For callers within Ukraine (domestic calls), the trunk prefix 0 is used, followed by the area code and the subscriber number. The full national significant number for a fixed-line subscriber in this code is 0 4571 XXX XX, where X represents the local subscriber digits. For example, a local number might be 0 4571 234 56. To call from abroad, the international access prefix (typically + or 00) is used, followed by Ukraine's country code 380, the area code without the leading zero, and the subscriber number. Thus, an international caller would dial +380 4571 234 56.

Local calls within the same area code (i.e., between Vasylkiv and Hlevakha) may be dialed using only the subscriber number if the operator supports abbreviated local dialing, but the standard practice is to dial the full national number. For calls from other regions of Ukraine, callers must dial 0 4571 followed by the local number. For calls from abroad, the +380 prefix replaces the trunk zero.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for this area; the 4571 code is the sole geographic code for the region. However, due to the proximity to Kyiv, some businesses may opt for non-geographic numbers or Kyiv city codes (44) for prestige, but fixed-line services in the specified towns are allocated under 4571. Subscriber numbers within this code typically have a length of 5 to 7 digits, depending on the operator and the specific exchange. The total number of digits after the country code (including the area code) is 9, making the full international number length 12 digits (including the +380 country code).

Practical Usage and Routing

This code is used for fixed-line telephony, including analog PSTN lines, ISDN, and increasingly VoIP-based fixed services that are registered to a physical address in the area. When calling a 4571 number, the call is routed through the Ukrainian national backbone to the appropriate local exchange. For international callers, the call terminates via an international gateway. It is important to note that while VoIP services are location-independent, numbers with this geographic code are typically tied to a physical location for emergency services (112) and regulatory purposes. Businesses operating in the area should ensure their contact numbers are correctly formatted for both domestic and international callers to avoid misdialing.
