Area Code 622 – Donetsk

Geographic Overview

The +380 622 area code is a geographic National Destination Code (NDC) assigned to the city of Donetsk and the surrounding urban area within the Donetsk Oblast of Ukraine. This code is 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 coverage includes the administrative center of Donetsk and its immediate suburban localities, which historically formed a significant industrial and economic hub in the eastern part of the country.

Dialing Formats

For callers within Ukraine, the national trunk prefix '0' is used before the area code. The local subscriber number for Donetsk typically consists of 5 to 7 digits, depending on the specific exchange and historical numbering capacity. Therefore, a national call to a Donetsk landline is dialed as: 0 622 XXX XX XX (where X represents the local subscriber digits). For international callers, the Ukrainian country code (+380) is used, followed by the area code without the leading '0'. The international format is: +380 622 XXX XX XX. For example, a local number 1234567 would be dialed as 0 622 1234567 domestically and +380 622 1234567 from abroad.

Caller Instructions

• Local callers (within Donetsk): If calling from a fixed line within the same exchange area, it may be possible to dial only the local subscriber number without the area code, depending on the specific network configuration. However, for calls from mobile phones or from other regions, the full national format (0 622 ...) is required.
• National callers (from other Ukrainian cities): Dial the trunk prefix '0', then the area code 622, followed by the subscriber number. Example: 0 622 1234567.
• International callers: Dial the international access prefix (e.g., 00 from most countries, or '+' from mobile), then the Ukrainian country code 380, then the area code 622 (without the leading '0'), and the subscriber number. Example: +380 622 1234567.

Overlay and Numbering Considerations

As of the latest ITU-T operational bulletins, there is no overlay code for the Donetsk geographic area. The 622 code remains the sole NDC for fixed-line services in this region. However, due to the ongoing geopolitical situation and administrative changes, the actual service availability and routing may be affected. Callers should be aware that some numbers in the Donetsk region may be served by alternative providers or may have been migrated to mobile or VoIP platforms, but the dialing format remains consistent with the geographic numbering plan.

Regulatory and Technical Notes

The Ukrainian numbering plan follows the closed dialing plan for fixed-to-fixed calls within the same NDC, but the use of the trunk prefix '0' is mandatory for all national calls outside the local area. The maximum length of a national significant number (NSN) is 9 digits, which includes the NDC (2 digits for 622) and the subscriber number (7 digits). This aligns with the E.164 recommendation. For VoIP and IP-based services, the same dialing rules apply when routing to the PSTN, ensuring interoperability.
