Area Code 3547 – Kozlov/Kozova, Ternopil

Geographic Overview

The area code 3547 is a geographic National Destination Code (NDC) within the Ukrainian public switched telephone network (PSTN), assigned to the town of Kozova (also transliterated as Kozliv or Kozlov) and its surrounding administrative district in the Ternopil 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 characterized by a mix of urban and rural settlements, with Kozova serving as the primary administrative and economic hub.

Geographic Coverage and Jurisdiction

The 3547 code covers the Kozova Raion (district), which includes the town of Kozova and numerous villages such as Zolota Sloboda, Teofipilka, and Khorobriv. The area is situated approximately 30 kilometers southeast of the regional capital, Ternopil. As a geographic code, it is tied to the physical telephone exchanges in this locality, and its use is mandatory for fixed-line services within the district. The code is not portable outside the geographic boundaries, meaning that subscribers cannot retain their 3547 numbers if they relocate to another region.

Dialing Formats and Instructions

For domestic callers within Ukraine, the number must be dialed in the national format: 0 (3547) XX-XX-XX, where the leading '0' is the trunk prefix, '3547' is the area code, and the subscriber number typically consists of six digits. For example, a local number might be 0 3547 2-34-56.

For international callers, the Ukrainian country code (+380) replaces the trunk prefix, and the area code is used without the leading '0'. The full international format is +380 3547 XX-XX-XX. For instance, a caller from abroad would dial +380 3547 2-34-56 to reach a fixed-line subscriber in Kozova.

When dialing locally within the same area code, the trunk prefix and area code may be omitted, and only the six-digit subscriber number is required. However, for clarity and to avoid errors, it is recommended to use the full national format.

Overlay and Numbering Considerations

As of the latest available data, there is no overlay code for the 3547 area. The numbering capacity is sufficient for the current subscriber base, and no major changes are anticipated in the near future. However, as with all geographic codes in Ukraine, the transition to all-IP networks (NGN) may influence future numbering assignments, but the geographic significance of the code is expected to remain.

Caller Instructions

• Local callers within the Kozova district can dial the subscriber number directly (without the area code) if the call is within the same exchange area. For calls from other districts in the Ternopil region, use the full national format.
• Long-distance callers from other regions of Ukraine must dial 0 3547 followed by the subscriber number.
• International callers must dial the international access prefix (e.g., 00 from most countries) followed by 380 3547 and the subscriber number.

It is important to note that the cost of calls to this geographic number varies depending on the caller's location and the service provider's tariff plan. Calls from mobile phones to fixed-line numbers in Kozova are typically charged at higher rates than on-net calls.
