Area Code 473 – Voronezh

Overview of Area Code +7 473

Area code +7 473 is a geographic National Destination Code (NDC) assigned to the Voronezh region (Voronezh Oblast) of the Russian Federation. It serves the administrative center, the city of Voronezh, as well as surrounding towns and rural localities within the oblast. The code is part of the Russian national numbering plan, which uses the international country code +7 (shared with Kazakhstan).

Geographic Coverage and Administrative Jurisdiction

The +7 473 area code covers the entire Voronezh Oblast, which is located in the southwestern part of European Russia, bordering Ukraine. The principal city is Voronezh, a major industrial, cultural, and administrative hub. Other significant localities served by this code include the cities of Borisoglebsk, Rossosh, Liski, and Ostrogozhsk, as well as numerous smaller settlements. The oblast is subdivided into districts, and the area code applies to both the city and the surrounding region.

Dialing Formats

For callers within Russia, the national trunk prefix is 8. To call a Voronezh number from another Russian city, dial 8-473-XXX-XX-XX. For international callers, the format is +7-473-XXX-XX-XX. The local subscriber number is seven digits long, and the area code is not optional when dialing from outside the region.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Voronezh region; the +7 473 code is the sole geographic code for the area. However, the Russian numbering plan allows for future overlays if the number pool becomes exhausted. In such a case, local calls would require 10-digit dialing (including the area code) even for calls within the same geographic region. As of now, local calls within Voronezh can be made using the seven-digit subscriber number alone, but callers from other regions must include the area code.

Caller Instructions

For local callers within Voronezh: dial the seven-digit subscriber number directly. For callers from other Russian regions: dial 8, then the area code 473, followed by the seven-digit number. For international callers: dial the international access code (e.g., 00 from most countries), then Russia's country code 7, then the area code 473, and the seven-digit subscriber number. Example: to call a number in Voronezh from the United States, dial 011-7-473-XXX-XX-XX.

Regulatory and Technical Notes

The Voronezh area code is managed by the Russian Federal Communications Agency (Rossvyaz). Both fixed-line and VoIP services operate under this code, and number portability is available for fixed-line numbers within the same geographic region. The code is used for both local and long-distance calls, and tariffs are determined by the operator and the distance of the call.
