Area Code 45 – Kyiv

Geographic Overview

The +380 45 area code is a geographic National Destination Code (NDC) assigned to the Kyiv region (Kyiv Oblast) of Ukraine. This code serves the administrative territory surrounding the capital city, Kyiv, but excludes the city of Kyiv itself, which uses the separate code +380 44. The region covered by +380 45 includes the oblast's administrative center, Kyiv (as a separate municipality), and numerous cities, towns, and rural areas within the oblast. Key settlements served by this code include Bila Tserkva, Brovary, Boryspil, Fastiv, Irpin (partially), and many smaller communities. The code is used for fixed-line (PSTN) services, and in some cases, it may also be used for VoIP services that are assigned geographic numbers.

Dialing Formats

When calling a number in the Kyiv region from within Ukraine, subscribers must dial the national trunk prefix 0, followed by the area code 45 and the subscriber's 7-digit local number. The complete national significant number (NSN) is 9 digits, excluding the trunk prefix. For example, a local number might be formatted as 0 45 XXX XX XX.

For international callers, the format is: +380 45 XXX XX XX (or 00380 45 XXX XX XX from many countries). The leading zero of the national trunk prefix is omitted when dialing from abroad.

Numbering Plan and Overlays

Ukraine's numbering plan follows ITU-T E.164 recommendations. The +380 45 code is a geographic code, meaning that the tariff and routing are based on the physical location of the line. There are no overlay codes currently in effect for this area; the code is unique to the Kyiv region. However, due to number portability, a subscriber may retain their +380 45 number even if they move to a different geographic area, but the number's geographic significance remains for routing and emergency services.

Caller Instructions

Local callers within the Kyiv region can often dial the 7-digit subscriber number directly without the area code, depending on the local exchange configuration. However, for clarity and consistency, it is recommended to always use the full national format: 0 45 XXX XX XX.

Callers from other regions of Ukraine must dial the trunk prefix 0, then 45, then the subscriber number. International callers must use the country code +380, then 45, then the subscriber number, omitting the trunk prefix 0.

Technical Considerations

The Kyiv region's telecommunications infrastructure is modern, with extensive fiber-optic and DSL broadband coverage. Calls to +380 45 numbers are routed over the PSTN or IP networks, and VoIP providers often offer reduced rates for calls to geographic numbers. Emergency services (112) are accessible from any fixed or mobile phone in Ukraine, regardless of the area code.
