Area Code 4636 – Varva, Chernihiv

Overview of Area Code +380 4636

Area code +380 4636 is a geographic destination code within the Ukrainian national numbering plan, assigned to the town of Varva and the surrounding Varva Raion in Chernihiv Oblast (province) of northern Ukraine. This code is part of the national destination code (NDC) structure defined under the ITU-T E.164 recommendation, and it is used for routing calls to fixed-line (PSTN) subscribers in the Varva district. The region is administratively part of the Chernihiv administrative jurisdiction, which lies approximately 200 kilometers northeast of the capital, Kyiv.

Geographic Coverage and Dialing Formats

The +380 4636 code covers the town of Varva and its adjacent rural settlements, including villages within the Varva Raion. The area is primarily residential and agricultural, with fixed-line services provided by the national incumbent operator and alternative local carriers. Subscriber numbers in this code typically consist of five to seven digits after the area code, resulting in a total national significant number (NSN) length of 9 digits (excluding the international prefix).

For callers within Ukraine, the local dialing format is 0 4636 XXX XX (where X represents the subscriber digits). For international callers, the format is +380 4636 XXX XX or +3804636XXXXX when dialed without spaces. For example, a local call to a Varva subscriber might be dialed as 0 4636 2 34 56, while an international caller would dial +380 4636 2 34 56.

Overlays and Numbering Considerations

As of the latest ITU-T national numbering plan updates, there are no overlay codes for the Varva area; the 4636 code is the sole geographic code for this locality. However, subscribers may have migrated to VoIP or mobile services, but the geographic code remains valid for fixed-line routing. Callers should note that when dialing from a mobile phone within Ukraine, the same trunk prefix '0' is used, followed by the area code and subscriber number.

Caller Instructions

For local callers within Varva, if dialing a number within the same area code, it may be possible to omit the area code in some local exchanges, but it is recommended to always include the full national number to avoid routing errors. For callers from other regions of Ukraine, dial 0 4636 followed by the subscriber number. For international callers, replace the trunk prefix '0' with the country code +380 and omit the leading '0' of the area code. Ensure you have the correct international exit code (e.g., 00 from most countries) when dialing from abroad.
