Area Code 3552 – Chortkiv, Ternopil

Geographic Overview

The +380 3552 area code is a geographic National Destination Code (NDC) assigned to the fixed-line telephone network serving Chortkiv and the surrounding Chortkiv Raion 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) and follows the ITU-T E.164 recommendation. Chortkiv, a historic city on the Seret River, functions as the administrative center for the raion, and the 3552 code covers the city itself along with adjacent rural exchanges.

Dialing Formats

For callers within Ukraine, the local dialing format requires the trunk prefix '0' followed by the area code and subscriber number: 0 3552 XXX XXX. For example, a local Chortkiv number might be dialed as 0 3552 4 12 34. When calling from abroad, the international format is +380 3552 XXX XXX, omitting the leading '0'. Subscriber numbers within this code typically consist of 5 to 7 digits, depending on the exchange capacity and historical allocation.

Geographic Coverage and Jurisdiction

This code is geographically tied to the Ternopil administrative region, which is subdivided into raions. Chortkiv Raion is one of the largest in the oblast, and the 3552 code serves not only the city of Chortkiv but also smaller towns and villages within the raion, such as Yahilnytsia, Bychiv, and Shmankivtsi. The code is administered by the national telecom regulator, and fixed-line services are provided by Ukrtelecom and other licensed operators that have deployed local loop infrastructure.

Overlays and Numbering Changes

As of the current numbering plan, there are no overlay codes for the 3552 area. However, in line with the gradual migration to a unified numbering space, all fixed-line numbers in Ukraine are being harmonized to a standard length. Callers should always use the full national number (including the leading '0') when dialing from a mobile phone, as per the national dialing rules. No special access codes are required for domestic long-distance calls; the trunk prefix '0' is sufficient.

Caller Instructions

For local callers within the same area code, it is possible to dial only the subscriber number, but this practice is becoming less common as the network modernizes. For international callers, the country code +380 must be used, followed by the area code without the leading '0'. For example, to call a Chortkiv number from the United States, one would dial 011 380 3552 XXX XXX. From the UK, the format is 00 380 3552 XXX XXX. It is important to note that the plus sign (+) in the international format represents the international access prefix, which varies by country.

Technical Considerations

Fixed-line numbers under 3552 are primarily used for PSTN and VoIP services, and they are not portable to mobile networks. However, number portability within fixed networks is available, allowing subscribers to retain their numbers when switching between fixed-line operators. The code is not used for mobile services; mobile numbers in Ukraine begin with 39, 50, 63, 66, 67, 68, 73, 91, 92, 93, 94, 95, 96, 97, 98, or 99. When dialing from abroad, ensure that you have the correct international exit code and that the total number of digits after the country code does not exceed 12, as per E.164.
