Area Code 5366 – Kremenchug, Poltava

Overview of Area Code +380 5366

Area code 5366 is a geographic National Destination Code (NDC) assigned to the city of Kremenchuk (also spelled Kremenchug) and its surrounding districts within the Poltava Oblast of Ukraine. Under the ITU-T E.164 international numbering plan, the full international dialing format for a subscriber number in this region is +380 5366 XXX XX, where +380 is the country calling code for Ukraine, 5366 is the NDC, and the remaining six digits constitute the local subscriber number. This code is part of the national numbering plan administered by the Ukrainian State Service of Special Communication and Information Protection, and it is allocated for fixed-line PSTN services.

Geographic Coverage and Jurisdiction

Kremenchuk is a major industrial center located in the central-eastern part of Ukraine, on the banks of the Dnipro River. The area code 5366 serves not only the city proper but also the Kremenchuk Raion (district) and several adjacent settlements. The region is known for the Kremenchuk Hydroelectric Power Plant, the KrAZ automobile plant, and the Kremenchuk Oil Refinery. The administrative jurisdiction falls under the Poltava Oblast, and the code is distinct from the Poltava city code (532) and other regional codes.

Dialing Formats

For callers within Ukraine, the national trunk prefix is 0. To call a Kremenchuk number from another Ukrainian city, you would dial: 0 5366 XXX XX. For example, a local number might be 5366 123 456 (hypothetical). From abroad, you would dial your country's international access code (e.g., 00 from most of Europe, 011 from the US/Canada), followed by Ukraine's country code 380, then the area code without the leading 0, and the subscriber number: +380 5366 123 456. When dialing within the same area code, local calls may be made using only the six-digit subscriber number, depending on the operator's dialing plan.

Caller Instructions

For local callers within Kremenchuk: if your telephone service provider supports abbreviated dialing, you can often dial just the 6-digit number. For callers from other regions of Ukraine: always use the national trunk prefix 0 followed by the area code 5366 and the subscriber number. For international callers: use the plus sign (+) or the appropriate international prefix, then 380, then 5366, then the number. Be aware that some mobile operators in Ukraine may require the full national number (0 5366 XXX XX) even for local calls when dialing from a mobile phone.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for the 5366 area. The number length is fixed at 9 digits after the country code (including the NDC). Number portability is available for fixed-line services, meaning a subscriber may retain their number when changing operators within the same geographic area. However, the geographic significance of the code remains tied to the physical location of the exchange, and calls are routed based on the NDC.
