Area Code 612 – Zaporozhye, Zaporizhzhia

Geographic Overview

The +380 612 area code is a geographic destination code assigned to the city of Zaporozhye (also spelled Zaporizhzhia) and its immediate suburban areas within the Zaporizhzhia Oblast of Ukraine. As part of the national numbering plan, this code routes calls to fixed-line PSTN subscribers within the city's administrative boundaries. Zaporozhye is a major industrial and administrative center on the Dnieper River, and the 612 code covers the central urban districts, including Oleksandrivskyi, Voznesenivskyi, and Khortytskyi, as well as adjacent settlements that fall under the city's municipal jurisdiction.

Dialing Formats

For callers within Ukraine, the national trunk prefix '0' is used before the area code, followed by the seven-digit local subscriber number. The complete national format is 0 612 XXX XX XX. For example, a local number might be dialed as 0 612 123 45 67.

For international callers, the Ukrainian country code +380 replaces the trunk prefix, and the area code is used without the leading zero. The international format is +380 612 XXX XX XX. Thus, the same number would be dialed from abroad as +380 612 123 45 67.

Caller Instructions

• Local callers within Zaporozhye: If you are dialing from a fixed or mobile phone within the same area code, you may often omit the trunk prefix and area code, dialing only the seven-digit subscriber number. However, for clarity and to avoid misrouting, it is recommended to use the full national format, especially when calling from mobile networks.
• Callers from other regions of Ukraine: Always dial the trunk prefix '0' followed by the area code 612 and the subscriber number. Example: 0 612 765 43 21.
• International callers: Dial your international access code (e.g., 00 from most countries), then Ukraine's country code 380, then the area code 612 (without the leading zero), and the subscriber number. Example: +380 612 765 43 21.

Overlay and Numbering Considerations

Currently, the 612 area code does not have an overlay code; the city is served solely by this geographic code. However, as with many Ukrainian cities, number portability is available for fixed-line services, allowing subscribers to retain their numbers when changing operators within the same geographic area. The seven-digit subscriber number space provides a theoretical capacity of up to 10 million numbers, though actual allocation is limited by technical and administrative factors.

From a technical standpoint, calls to +380 612 numbers are routed via the Ukrainian PSTN and are subject to standard national and international interconnection agreements. VoIP providers must ensure proper routing to the Ukrainian network, and callers using VoIP services should be aware that emergency services (112) are accessed via a separate universal number, not through this geographic code.
