Area Code 3451 – Chkalovsk

Geographic Overview

The area code 3451 is a geographic National Destination Code (NDC) assigned to the city of Chkalovsk (also known as Buston since 2016) in the Sughd Region of northwestern Tajikistan. This code is part of the national numbering plan administered by the Communications Service under the Government of the Republic of Tajikistan, in accordance with ITU-T E.164 recommendations. Chkalovsk is situated near the larger city of Khujand and the Kairakkum Reservoir, and its economy historically centered on the Chkalovsk Mining and Chemical Combine. The geographic area served by this code includes the urban settlement of Chkalovsk and its immediate administrative surroundings.

Dialing Formats

For callers within Tajikistan, the national trunk prefix is 8, followed by the area code and the subscriber number. Local numbers in Chkalovsk typically consist of 6 digits after the area code. Thus, a national call from another region would be dialed as: 8 3451 XX XX XX. For international callers, the format is: +992 3451 XX XX XX, where +992 is the country calling code for Tajikistan. When dialing locally within Chkalovsk, the area code may be omitted, and only the 6-digit subscriber number is used.

Administrative and Regulatory Notes

As a geographic code, 3451 is tied to the physical location of the fixed-line subscriber. However, with the growth of VoIP and mobile services, some numbers may be used for nomadic services, but the code remains officially designated for fixed-line services in the Chkalovsk area. There are no known overlay codes for this region; the numbering capacity is sufficient for the current population density. Callers should note that international dialing from Tajikistan requires the international prefix 00 (or + on mobile networks) followed by the country code, area code (without the leading 0, if applicable), and subscriber number.

For example, to reach a fixed line in Chkalovsk with subscriber number 123456, an international caller would dial +992 3451 123456. This format ensures proper routing through the international gateway to the Tajikistan PSTN.
