Area Code 4655 – Sosnitsa, Chernihiv

Geographic Overview

Dialing Formats and Instructions

For callers within Ukraine, the national trunk prefix '0' must be dialed before the area code, followed by the subscriber number. The complete national format is 0 4655 XX-XX, where 'XX-XX' represents the 4-digit local subscriber line. For example, a local Sosnitsa number might be 0 4655 3-45-67.

International callers must replace the trunk prefix with Ukraine's country calling code +380, omitting the leading '0'. The international format becomes +380 4655 XX-XX. For instance, dialing from abroad: +380 4655 3-45-67.

Geographic Coverage and Administrative Notes

The 4655 exchange primarily serves the urban-type settlement of Sosnitsa, which functions as the administrative center of the Sosnytskyi Raion. The coverage area extends to nearby rural communities within the raion, including villages such as ... (list not exhaustive). Subscriber lines under this prefix are typically fixed-line connections, including analog POTS and digital ISDN services, provided by the national incumbent operator Ukrtelecom and alternative local fixed-line operators.

No overlay area code is currently active for this region, meaning the 4655 code is unique to the Sosnitsa exchange. However, number portability within Ukraine allows subscribers to retain their numbers when switching between fixed-line operators, provided they remain within the same geographic area.

Caller Instructions

• Local callers: Dial the 7-digit national number (0 4655 XX-XX) from any phone in Ukraine, regardless of the caller's location.
• International callers: Dial your country's exit code (e.g., 00 from most European countries, 011 from North America), followed by 380, then 4655, and the 4-digit subscriber number. Example: 00 380 4655 3-45-67.

When calling from abroad, ensure you omit the '0' trunk prefix; otherwise, the call will fail. Always verify the subscriber number length, as some local numbers may have fewer digits due to historical allocations.
