Area Code 6447 – Luhansk

Geographic Overview

The +380 6447 prefix is a geographic National Destination Code (NDC) assigned to the Luhansk region of Ukraine, specifically serving the administrative district and its surrounding settlements. Under the ITU-T E.164 numbering plan, this code routes calls to fixed-line PSTN subscribers within the designated geographic area. The Luhansk region, located in the eastern part of the country, has historically been served by this code for landline telephony.

Dialing Formats

For callers within Ukraine, the national trunk prefix '0' is used before the area code. The full national significant number (NSN) for a subscriber in this region is 10 digits long, formatted as 0 6447 XXX XX. For example, a local number might be 0 6447 12345. When dialing from abroad, the country code +380 is used, followed by the area code without the leading '0', resulting in the international format +380 6447 XXX XX. For instance, a call to the same number would be dialed as +380 6447 12345.

Geographic Coverage and Administrative Jurisdiction

The 6447 code covers the Luhansk district and its adjacent areas, which include the city of Luhansk and nearby towns. This code is part of the geographic numbering plan of Ukraine, where each NDC corresponds to a specific administrative region. The Luhansk region has a complex telecommunications history due to geopolitical changes, but the numbering plan remains officially assigned for fixed-line services.

Caller Instructions

Local callers within the same area code can often dial the subscriber number directly without the area code, depending on the local dialing rules. However, for calls from other regions in Ukraine, the full national format 0 6447 XXX XX must be used. International callers should replace the trunk prefix '0' with the country code +380 and omit the leading '0' of the area code. For example, a caller from the United States would dial 011 380 6447 XXX XX.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Luhansk region; the 6447 code is the sole geographic code for this area. Numbering capacity is managed by the Ukrainian regulator, and number portability may allow subscribers to retain their numbers when changing operators, but geographic codes remain tied to the location of the fixed line.

Technical Notes

This prefix is used exclusively for PSTN (Public Switched Telephone Network) services. VoIP and mobile services are assigned non-geographic codes and are not covered by this prefix. When routing international calls, carriers must ensure that the called number is correctly formatted to avoid misrouting. The +380 country code is shared by all Ukrainian geographic and non-geographic codes.
