Area Code 3652 – Zdolbunov, Rivne

The +380 3652 prefix is a geographic National Destination Code (NDC) assigned to the fixed-line telephone network serving the city of Zdolbuniv and its surrounding areas within the Rivne Oblast of 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. As a geographic code, it routes calls to a specific physical exchange area, distinguishing it from non-geographic mobile or VoIP prefixes.

Geographic Coverage and Administrative Jurisdiction

The 3652 area code covers Zdolbuniv, a city of regional significance in the Rivne Oblast, located approximately 20 kilometers south of the regional capital, Rivne. The code also serves the Zdolbuniv Raion, including nearby settlements such as Zdovbytsia, Mirotin, and other villages within the raion. The administrative jurisdiction falls under the Rivne Oblast, which is in the northwestern part of Ukraine.

Dialing Formats and Instructions

For callers within Ukraine, the national trunk prefix '0' is used before the area code. The full national number is 0 3652 XX XX XX, where '0' is the trunk prefix, '3652' is the NDC, and the subscriber number is typically 6 digits long, resulting in a total national significant number length of 9 digits (excluding the trunk prefix). For example, a local number in Zdolbuniv might be 0 3652 4 12 34.

For international callers, the country calling code +380 is used, followed by the area code without the leading '0'. The international format is +380 3652 XX XX XX. For instance, to call a number in Zdolbuniv from abroad, you would dial +380 3652 4 12 34. If you are calling from a mobile phone within Ukraine, you can also use the international format with the '+' sign, but the national format with '0' is equally valid.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for the 3652 area. The code is exclusively used for fixed-line services in the Zdolbuniv area. Subscribers may have the ability to keep their numbers when switching between fixed-line operators due to number portability, but the geographic significance of the code remains tied to the location of the exchange.

Caller Instructions

Local callers within the Zdolbuniv area may be able to dial only the subscriber number for calls within the same exchange, depending on the operator's configuration. However, for calls from other regions of Ukraine, the full national format (0 3652 XX XX XX) is required. Foreign callers must always include the country code (+380) and omit the trunk prefix '0'.
