Area Code 6431 – Anthracite, Luhansk

Geographic Overview and Administrative Coverage

The Ukrainian national destination code +380 6431 is a geographic area code assigned to the city of Anthracite (formerly known as Krasnyi Luch) and its surrounding administrative districts within the Luhansk Oblast. This code falls under the broader 0643 numbering zone, which historically served the southern part of the Luhansk region. The area covered by +380 6431 includes the city of Anthracite itself, as well as smaller towns and rural settlements within the Anthracite Raion. Due to the ongoing conflict in eastern Ukraine, the actual administrative control of this territory may be disputed; however, the numbering plan remains officially allocated by the Ukrainian National Commission for State Regulation of Communications and Informatization (NKRZI).

Dialing Formats and Caller Instructions

For callers within Ukraine, reaching a subscriber in Anthracite requires dialing the trunk prefix 0, followed by the area code 6431, and then the local subscriber number. The local numbers in this area typically consist of 5 to 7 digits, depending on the specific exchange. An example of a local number in international format would be +380 6431 2XXXXX, where the '2' is part of the local number. For international callers, the format is: +380 (Ukraine's country code) followed by 6431 and the subscriber number, omitting the leading '0' of the trunk prefix. Thus, a complete international dialing sequence would be +380 6431 XXXXXX.

When dialing from a foreign country, ensure you use the international exit code of your country (e.g., 00 from most European countries, 011 from the United States) before the +380 number. For local calls within Anthracite, the area code may be omitted if the call is made within the same local calling area, but it is always safer to include it to avoid misrouting.

Important Considerations for Callers

Due to the volatile situation in the Luhansk region, network availability and call routing may be affected. Some mobile operators may route calls to this area through alternative infrastructure, and there is a possibility of increased latency or call failures. It is advisable to check with your service provider for any special dialing instructions or restrictions. Additionally, as with all geographic numbers in Ukraine, the cost of calling +380 6431 depends on your operator's tariff plan, and calls from mobile phones may be charged differently than from landlines.
