Area Code 4634 – Talalayevka, Chernihiv

Overview of Area Code +380 4634

Area code 4634 is a geographic destination code within the Ukrainian national numbering plan, assigned to the town of Talalayivka and its surrounding rural districts in the Chernihiv Oblast (province) of northern Ukraine. This code is part of the country's closed dialing plan, meaning that all national calls—whether local or long-distance—require the full 10-digit subscriber number, including the leading '0' trunk prefix. For international callers, the Ukrainian country code +380 replaces the trunk prefix, and the area code is dialed without the leading zero.

Geographic Coverage and Administrative Jurisdiction

Talalayivka serves as the administrative center of the Talalayivka Raion (district) within Chernihiv Oblast. The area code 4634 covers the town itself and the adjacent villages that rely on the local PSTN (Public Switched Telephone Network) infrastructure. The region is predominantly rural, with agriculture and small-scale manufacturing forming the economic base. The code is managed by the Ukrainian State Service of Special Communication and Information Protection, in accordance with ITU-T E.164 recommendations.

Dialing Formats and Caller Instructions

For local callers within Ukraine (including those in the same oblast), the national format is:

• National (domestic) dialing: 0 4634 XXX XX (where X represents the local subscriber number digits).
• International dialing from abroad: +380 4634 XXX XX.

For example, to reach a fixed-line subscriber in Talalayivka with the local number 2 34 56, a caller from Kyiv would dial 0 4634 2 34 56, while a caller from the United States would dial 011 380 4634 2 34 56 (or simply +380 4634 2 34 56 from a mobile phone).

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for this area; 4634 remains the sole geographic code for Talalayivka. However, subscribers in the region may have been migrated to fiber-optic or VoIP infrastructure, but the geographic code remains tied to the physical location. Number portability exists within Ukraine, allowing users to retain their numbers when switching operators, but geographic codes generally remain associated with the original location for fixed-line services.

Practical Information for Callers

When calling from abroad, always verify the current time difference (Ukraine is UTC+2, or UTC+3 during daylight saving time). Be aware that international call rates vary by carrier, and some VoIP services may treat calls to geographic numbers as domestic if they have a Ukrainian point of presence. For emergency services, dial 101 (fire), 102 (police), or 103 (ambulance) from any phone in Ukraine, regardless of the area code.
