Area Code 3365 – Kivertsi/Tsuman, Volyn

Geographic Overview

The +380 3365 prefix is a geographic National Destination Code (NDC) assigned to the Kivertsi and Tsuman areas within the Volyn Oblast of Ukraine. This region is located in the northwestern part of the country, and the code serves both the town of Kivertsi and the urban-type settlement of Tsuman, along with the surrounding rural districts. The administrative center of Volyn Oblast, Lutsk, is in close proximity but uses a different area code (0332).

Dialing Formats

For callers within Ukraine, the national trunk prefix '0' is used before the area code, followed by the subscriber number. The complete national format is 0 3365 XX-XX-XX, where 'X' represents the local subscriber digits. For international callers, the country code for Ukraine (+380) replaces the trunk prefix, resulting in the format +380 3365 XX-XX-XX. When dialing from abroad, you must omit the leading '0' of the trunk prefix.

Numbering Structure

Subscriber numbers within the +380 3365 code typically consist of 6 or 7 digits, depending on the specific local exchange and the historical allocation. The total length of a national significant number (NSN) in Ukraine is 9 digits, which includes the area code and subscriber number. For example, a typical number might be formatted as 0 3365 4-12-34 (national) or +380 3365 4-12-34 (international).

Caller Instructions

Local callers within the Kivertsi/Tsuman area can often dial only the subscriber number without the area code, depending on the local exchange configuration. However, it is always safe to use the full national format to avoid misdialing. Long-distance callers within Ukraine must dial the trunk prefix '0' followed by the area code and subscriber number. International callers should dial their country's exit code (e.g., 00 from most European countries, 011 from the US/Canada), then Ukraine's country code 380, then the area code 3365 (without the leading zero), and finally the subscriber number.

Regulatory and Technical Notes

This geographic code is allocated by the Ukrainian State Centre of Radio Frequencies (UCRF) under the National Commission for State Regulation of Communications and Informatization. The code is part of the national numbering plan that complies with ITU-T E.164 recommendations. As of the latest updates, there are no overlay codes in this area, meaning that the 3365 code is the sole geographic code for the region. However, number portability exists in Ukraine, so a number with this prefix might be routed to a different operator or even a different region, but the geographic identity remains for billing and emergency services purposes.
