Area Code 3543 – Podvolochisk, Ternopil

Overview of Area Code +380 3543

Area code +380 3543 is a geographic destination code assigned to the town of Podvolochisk (also spelled Pidvolochysk) and its surrounding rural districts within the Ternopil Oblast of western Ukraine. This code is part of the national numbering plan administered by the Ukrainian State Centre of Radio Frequencies under the framework of ITU-T E.164. It is used exclusively for fixed-line PSTN and VoIP services that are physically or administratively located within this specific administrative district.

Geographic Coverage and Jurisdiction

The code covers the urban-type settlement of Podvolochisk, which serves as the administrative center of the Podvolochysk Raion. The area is situated approximately 50 kilometers east of the regional capital Ternopil, along the Zbruch River near the Khmelnytskyi Oblast border. Subscribers within this numbering area include residential customers, local businesses, and government institutions in the town and nearby villages such as Staromishchyna, Sukhivtsi, and Ivane-Puste. The geographic nature of the code means that each subscriber line is tied to a physical address, and the tariff structure for calls to this code is typically lower than calls to mobile or non-geographic numbers.

Dialing Formats and Caller Instructions

For callers within Ukraine, the national trunk prefix 0 must be dialed before the area code. Thus, a local number in Podvolochisk is dialed as 0 3543 XX-XX-XX (where X represents the subscriber's seven-digit number). For example, a local landline number might be 0 3543 2-45-67. When calling from abroad, the international access prefix (typically 00 or +) is used, followed by Ukraine's country code 380, then the area code without the leading zero, and the subscriber number: +380 3543 2-45-67. It is important to note that the area code is an integral part of the national numbering plan; omitting the trunk prefix when dialing domestically will result in a failed call.

Overlay and Numbering Considerations

As of the latest ITU-T recommendations, there is no overlay code for the Podvolochisk area. The code 3543 operates as a standalone geographic area code, and all fixed-line numbers within this region are assigned under this single code. However, due to the ongoing migration of PSTN networks to IP-based infrastructure, some subscribers may have VoIP-enabled lines that still retain the geographic code. For international callers, it is essential to verify the current number length and dialing procedures with the service provider, as the Ukrainian numbering plan has undergone several changes since the 1990s. Always confirm the complete number with the called party to avoid misdialing.
