Area Code 623 – Krasnoarmeysk/Makeyevka, Donetsk

Overview of Area Code +380 623

Area code 623 is a geographic destination code within the Ukrainian national numbering plan, assigned to the Donetsk region of eastern Ukraine. Specifically, it serves the city of Krasnoarmiysk (also known as Pokrovsk) and the surrounding localities, including the city of Makeyevka (Makiivka). This code is part of the country's public switched telephone network (PSTN) and is used for fixed-line telephony services.

Geographic Coverage and Administrative Jurisdiction

The code covers the administrative districts of Krasnoarmiysk and Makeyevka within the Donetsk Oblast. Krasnoarmiysk, a city of regional significance, is an important railway and industrial hub. Makeyevka, located near Donetsk, is a major coal-mining and metallurgical center. The area is served by a mix of urban and rural subscribers, with local exchanges providing connectivity to residential and business customers.

Dialing Formats

To call a fixed-line number in this region, the following formats apply:

• National dialing (within Ukraine): Dial 0 623 XXX XXX (where X represents the subscriber number). The leading 0 is the trunk prefix used for domestic calls.
• International dialing (from abroad): Dial +380 623 XXX XXX (or 00 380 623 XXX XXX from most countries). The +380 is the country code for Ukraine, and the 623 is the national destination code (NDC).

For example, a local number might be +380 623 123 456. When calling from a mobile phone in Ukraine, the same international format is often used, but the national format with 0 is also valid.

Overlay and Numbering Considerations

Currently, there is no overlay code for this area; 623 is the sole geographic code for the region. Subscriber numbers are typically six digits long, resulting in a total number length of 12 digits when including the country code and NDC (excluding the trunk prefix). The numbering plan follows the ITU-T E.164 recommendation, ensuring international compatibility.

Caller Instructions

• Local callers: If you are within the same area code, you may be able to dial the six-digit subscriber number directly, but to avoid confusion, it is recommended to use the full national format 0 623 XXX XXX.
• International callers: Replace the trunk prefix 0 with your country's international access code (e.g., 011 from the US, 00 from most European countries), then dial 380 followed by 623 and the subscriber number.

Note that due to the ongoing conflict in the Donetsk region, some fixed-line services may be disrupted or rerouted. It is advisable to verify the current status with your service provider.
