Area Code 4140 – Natives, Zhytomyr

Geographic Overview

The Ukrainian country code +380, followed by the national destination code (NDC) 4140, routes calls to the Zhytomyr region, specifically the city of Zhytomyr and its surrounding areas. This is a geographic allocation under the national numbering plan, administered by the Ukrainian State Centre of Radio Frequencies (UCRF). The NDC 4140 is part of the Zhytomyr oblast's numbering zones, which are subdivided into smaller local exchange areas. The region is an administrative and cultural hub in northern Ukraine, with Zhytomyr city serving as the oblast capital.

Dialing Formats

For international callers, the full number comprises the country code, the NDC (without the leading zero), and the subscriber number. For example, a local landline number in Zhytomyr might be formatted as +380 4140 12345 (or +380414012345 when written contiguously). Within Ukraine, callers must use the trunk prefix '0' before the NDC, resulting in the national format: 0 4140 12345. When dialing from a mobile phone within Ukraine, the same national format is used. It is important to note that the subscriber number length may vary, but the total length of the national significant number (NDC + subscriber number) is typically 9 digits, excluding the trunk prefix.

Geographic Coverage and Overlays

The 4140 code covers the city of Zhytomyr and adjacent districts within the Zhytomyr oblast. It is one of several NDCs assigned to the region; other codes, such as 412, may serve different parts of the oblast or specific exchanges. There are no overlay codes currently in effect for this area, meaning that local calls within the same NDC do not require the area code. However, calls from other regions or mobile networks must include the full national number.

Caller Instructions

For local callers within the Zhytomyr area (same NDC), only the subscriber number is dialed. For callers from other regions in Ukraine, dial 0, then 4140, followed by the subscriber number. For international callers, dial the international access prefix (e.g., 00 from most countries, or + from mobile), then 380, then 4140, and the subscriber number. Remember to omit the trunk prefix '0' when calling from abroad.

Regulatory and Technical Notes

As with all geographic numbers in Ukraine, the 4140 code is assigned to fixed-line operators, including Ukrtelecom and alternative providers. Number portability is available within Ukraine, allowing users to retain their numbers when changing operators, but porting between geographic and mobile codes is generally not permitted. Calls to 4140 numbers are charged according to the caller's tariff plan; international rates apply for calls from outside Ukraine. For emergency services, always dial 101 (fire), 102 (police), or 103 (ambulance) regardless of location.
