Area Code 4591 – Ivankiv, Kyiv

Geographic Overview and Administrative Jurisdiction

The +380 4591 prefix is a geographic National Destination Code (NDC) assigned to the Ivankiv district within the Kyiv Oblast (Kyiv Region) of Ukraine. Ivankiv is a settlement of district significance, serving as the administrative center of the Ivankiv Raion. This area is located in the northern part of the Kyiv Oblast, along the Teteriv River, and is known for its proximity to the Chernobyl Exclusion Zone. The code covers the town of Ivankiv and the surrounding rural localities, including villages such as Dytyatky, Strakholissya, and others within the district.

Dialing Formats and Caller Instructions

When calling a landline in Ivankiv from within Ukraine, subscribers must dial the national trunk prefix 0, followed by the area code 4591, and then the local subscriber number, which typically consists of 5 to 7 digits. For example, a local number might be dialed as 0 4591 2 34 56. From abroad, callers should dial the international access code (e.g., 00 from most countries), then Ukraine's country code 380, followed by the area code 4591 (without the leading zero) and the subscriber number: +380 4591 2 34 56.

It is important to note that Ukraine implemented a new dialing plan in 2009, which standardized the use of the leading '0' for all national calls. The area code 4591 is part of the geographic numbering plan, and its use is mandatory for all calls to landlines in the Ivankiv area, regardless of whether the caller is using a fixed line or a mobile phone.

Overlay and Numbering Plan Considerations

As of the latest available data, there is no overlay code for the Ivankiv area, meaning that the 4591 code is the sole geographic code for this region. However, the Kyiv Oblast has been experiencing a gradual transition towards a unified numbering plan, and subscribers in some areas may be required to dial additional digits in the future. For now, the standard dialing procedures remain in effect.

Practical Information for Callers

For local callers within Ivankiv, it is possible to dial the subscriber number directly without the area code, but this practice is discouraged due to the potential for confusion, especially with the increasing use of VoIP and mobile services. For international callers, it is essential to verify the correct local number length, as some numbers may have been migrated to the national numbering plan. Always confirm the number with the recipient to ensure accuracy.

Ivankiv is a rural area, and its telecommunications infrastructure is primarily served by fixed-line operators, with mobile coverage provided by all major Ukrainian MNOs. The area code 4591 is exclusively used for fixed-line services, and mobile numbers in the region are assigned non-geographic prefixes (e.g., 50, 63, 67, 68, 73, 91, 92, 93, 94, 95, 96, 97, 98, 99).
