Overview

The area code 4646 is a geographic National Destination Code (NDC) assigned to the Desna, Kozelets, and Oster areas within the Chernihiv Oblast of Ukraine. It is part of the national numbering plan under the country calling code +380. This code is used for fixed-line telephone services (PSTN) and is associated with the northern-central region of the country, along the Desna River.

Geographic Coverage and Administrative Jurisdiction

The code 4646 serves the town of Kozelets (the administrative center of Kozeletskyi Raion), the urban-type settlement of Desna, and the historic town of Oster. These localities are situated in the Chernihiv Oblast, which borders Kyiv Oblast to the south. The region is primarily residential and agricultural, with local businesses and public services relying on this fixed-line code.

Dialing Formats

To call a subscriber within the 4646 area, you must use the appropriate national or international format. The local number length is typically 5 digits for subscribers in smaller settlements, but may vary. The complete international dialing format is:

• International: +380 4646 XXX XX (from outside Ukraine)
• National (within Ukraine): 0 4646 XXX XX (from a different fixed-line or mobile network)
• Local (within the same code): XXX XX (subscriber number only, if supported by the local exchange)

For example, if a subscriber number is 12345, you would dial:

• From the United States: 011 380 4646 12345
• From a Ukrainian mobile phone: 04646 12345
• From another country in Europe: 00 380 4646 12345

Overlay and Numbering Considerations

As of the latest ITU-T E.164 updates, there is no overlay code for 4646; it is a standalone geographic code. However, subscribers may have migrated to VoIP or mobile services, but the geographic code remains in use for fixed-line connections. When calling from abroad, always replace the leading zero of the national significant number with the +380 country code.

Caller Instructions

For callers inside Ukraine: Dial the full national number including the trunk prefix '0' and the area code 4646. For example, to call a number 12345 in Kozelets from Kyiv, dial 04646 12345.

For callers outside Ukraine: Dial your international access code (e.g., 011 from the US, 00 from most European countries), followed by Ukraine's country code 380, then the area code 4646 (without the leading 0), and the subscriber number. Example: +380 4646 12345.

Note that calls to this geographic number are typically charged at standard international rates when dialed from abroad, and at national fixed-line rates when dialed domestically.
