Area Code 6237 – Selidus, Donetsk

Overview of Area Code 6237

Area code 6237 is a geographic National Destination Code (NDC) within the Ukrainian public switched telephone network (PSTN), specifically assigned to the town of Selidus (also transliterated as Selydove) in the Donetsk Oblast of eastern Ukraine. This code forms part of the national numbering plan administered by the Ukrainian State Centre of Radio Frequencies (UCRF) under the framework of ITU-T E.164. The geographic area covered by this code is characterized by its coal-mining heritage and industrial base, with Selidus serving as a local administrative and economic hub.

Geographic Coverage and Administrative Jurisdiction

The 6237 code covers the city of Selidus and its surrounding settlements within the Pokrovsk Raion of Donetsk Oblast. This region has been significantly affected by the ongoing conflict in eastern Ukraine, which may impact the availability and routing of fixed-line services. The administrative jurisdiction falls under the Donetsk regional council, and the code is managed by the national telecommunications operator Ukrtelecom, along with alternative fixed-line operators that have been granted access to the local loop.

Dialing Formats and Caller Instructions

For callers within Ukraine, the national dialing format requires dialing 0 followed by the area code and the subscriber number. For example, to reach a fixed-line subscriber in Selidus with a local number of 123456, you would dial 0 6237 123456. The trunk prefix '0' is used for all domestic calls to geographic numbers, and the total length of the national significant number (NSN) is nine digits (excluding the trunk prefix).

For international callers, the Ukrainian country code +380 replaces the trunk prefix '0'. Thus, the same number would be dialed as +380 6237 123456 from any country outside Ukraine. It is essential to omit the leading '0' of the area code when dialing internationally, as the plus sign and country code already include the necessary routing information.

Overlay Considerations and Numbering Changes

As of the latest available data, there is no overlay code for the 6237 area. Subscribers in Selidus retain the traditional seven-digit local numbering format (the area code plus a five-digit subscriber number). However, given the dynamic nature of the conflict and potential administrative changes, it is advisable to verify current numbering resources with the Ukrainian regulator if you are planning to deploy services in this region.

Practical Usage Notes

• Fixed-line numbers in this area are primarily used for residential and business landlines, as well as for public payphones and emergency services.
• When calling from a mobile phone within Ukraine, the same national dialing format (0 6237 ...) applies, but mobile operators may apply different tariffs for calls to fixed-line numbers.
• For international callers, consider time zone differences (Ukraine is UTC+2, UTC+3 in summer) when scheduling calls.
• Due to the ongoing situation, some fixed-line infrastructure may be damaged or temporarily out of service; alternative communication methods may be necessary.
