Area Code 3433 – Kolomyia, Ivano-Frankivsk

Overview of Area Code +380 3433

Area code +380 3433 is a geographic National Destination Code (NDC) assigned to the city of Kolomyia and its surrounding districts within the Ivano-Frankivsk Oblast of western Ukraine. This code is part of the national numbering plan administered by the Ukrainian State Centre of Radio Frequencies (UCRF) under the framework of ITU-T E.164. The region is known for its Carpathian foothills, historic architecture, and cultural significance, making it a hub for local businesses, government offices, and tourism-related services.

Geographic Coverage and Administrative Jurisdiction

The code 3433 serves the urban area of Kolomyia, the administrative center of Kolomyia Raion, as well as nearby settlements and rural communities within the raion. Major localities covered include the town of Horodenka and several villages along the Prut River valley. The Ivano-Frankivsk Oblast is one of Ukraine's western regions, bordering Romania and Moldova to the south, and is part of the historical region of Galicia. The area code is distinct from the larger Ivano-Frankivsk city code (+380 342), which covers the regional capital.

Dialing Formats and Number Structure

When calling a landline in Kolomyia from within Ukraine, the national trunk prefix 0 is used, followed by the area code and the subscriber number. The full national format is: 0 3433 X XX XX. For example, a local number might be 0 3433 5 12 34. Internationally, callers must use the country code +380, then the area code (without the leading zero) and the subscriber number: +380 3433 5 12 34. Subscriber numbers in this area typically consist of 5 to 7 digits, but the total length of the national significant number (NSN) is always 9 digits, including the area code.

Caller Instructions

• Local callers (within the same area code) may often dial only the subscriber number, but for clarity and to avoid misdialing, it is recommended to use the full national format, especially with the increasing use of VoIP and mobile networks.
• Callers from other Ukrainian cities must dial 0 3433 followed by the subscriber number, regardless of the operator.
• International callers should replace the trunk prefix with the country code: +380 3433 followed by the subscriber number.

Overlay and Numbering Considerations

As of the latest ITU-T operational bulletin, there are no overlay codes for the Kolomyia area. The numbering capacity is managed to accommodate local demand, and number portability is available for fixed-line services, allowing subscribers to retain their numbers when switching between operators within the same geographic area. However, geographic numbers are generally tied to the physical location of the line, and moving outside the area may require a number change.

Practical Usage

This area code is used by residential and business fixed-line subscribers, including local administrative bodies, schools, medical facilities, and commercial enterprises. When contacting services in Kolomyia from abroad, ensure you have the correct subscriber number, as some businesses may also list mobile numbers with different prefixes. Always verify the number with the recipient to avoid misdialing.
