Area Code 6240 – Gorlovka, Donetsk

Geographic Overview

The +380 6240 prefix is a geographic National Destination Code (NDC) assigned to the city of Horlivka (Gorlovka) and its surrounding areas within the Donetsk region of Ukraine. This code follows the ITU-T E.164 international numbering standard, ensuring global interoperability. Horlivka is an important industrial center in eastern Ukraine, known for coal mining and chemical production. The geographic area served by this code includes the city proper and adjacent settlements, with numbering capacity allocated by the Ukrainian National Commission for State Regulation of Communications and Informatization.

Dialing Formats

For callers within Ukraine, the local dialing format is 0 6240 XX XX XX (national trunk prefix '0' followed by the NDC and subscriber number). For international callers, the format is +380 6240 XX XX XX (country code +380, NDC without the leading '0', and the subscriber number). The total number length after the country code is typically 9 digits, including the NDC.

Caller Instructions

• Local callers (within Horlivka): In most cases, local calls may be dialed using the 6-digit subscriber number without the area code, but this depends on the local network configuration. However, due to the ongoing situation in the region, it is advisable to always use the full national format (0 6240 ...) to ensure proper routing.
• National callers (from other Ukrainian cities): Dial 0 6240 followed by the subscriber number. For example, to call a Horlivka number 123456, dial 0 6240 123456.
• International callers: Dial your country's international access code (e.g., 00 from most European countries, 011 from the US/Canada), then 380 6240 and the subscriber number. For example, from the US, dial 011 380 6240 123456.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for Horlivka; the 6240 code is the sole geographic code for the city. However, due to the administrative changes and the ongoing conflict in the Donetsk region, some numbers may be routed through alternative infrastructure. Callers should be aware that network coverage and routing may be affected by the current situation, and it is recommended to verify the availability of services with your telecom provider.

Regulatory and Technical Notes

The Ukrainian numbering plan follows the ITU-T E.164 recommendation, and the NDC 6240 is part of the geographic numbering scheme. The allocation of numbers is managed by the Ukrainian regulator, and all numbers under this code are assigned to fixed-line services, including PSTN and VoIP that are tied to a physical address in the area. Mobile numbers in Ukraine are identified by separate NDCs (e.g., 67, 68, 96, 97, 98, 50, 66, 95, 99, 63, 73, 91, 92, 93, 94), so 6240 is exclusively for fixed-line services. For accurate billing and routing, it is essential to use the correct international format when dialing from abroad.
