Area Code 813 – Leningrad region

Geographic Overview

The +7 813 area code is a geographic National Destination Code (NDC) assigned to the Leningrad Oblast of the Russian Federation. This region surrounds, but does not include, the federal city of Saint Petersburg, which uses the separate code +7 812. The 813 code covers a vast territory, including the administrative center of Gatchina, as well as other significant towns such as Vyborg, Kingisepp, Luga, Tikhvin, and Kirishi. These areas are part of the Northwestern Federal District and are served by the North-West Main Department of the Central Telegraph and Telephone Network.

Dialing Formats

For callers within Russia, reaching a subscriber in the 813 zone requires trunk prefix 8, followed by the area code and the subscriber number. For example, to call a landline in Gatchina with the number 123-45-67, you would dial: 8 813 123-45-67. From abroad, the international format is used: +7 813 123-45-67 (or 007 813 123-45-67 from some legacy systems). The subscriber number length within the 813 code is typically seven digits, making the total international number length 11 digits (including the country code).

Geographic Coverage and Administration

The 813 code is administered by PJSC Rostelecom, the national telecommunications operator, and is part of the Russian numbering plan. It is a geographic code, meaning that the tariff and routing are based on the physical location of the line. The region is subdivided into several local telephone networks, each with its own range of subscriber numbers. For instance, Vyborg and Priozersk have their own numbering blocks within the 813 code. The code is used exclusively for fixed-line services; mobile numbers in the same area use the non-geographic prefixes 9xx, which are not tied to a specific region.

Caller Instructions

Local callers within the 813 zone can often dial the seven-digit subscriber number directly without the area code, depending on the specific local network configuration. However, for calls from other parts of Russia or from abroad, the full national or international format is mandatory. When calling from a mobile phone in Russia, it is common to use +7 instead of 8, as the +7 format is universally accepted. For international callers, always use +7 followed by the area code and number, omitting the leading 8 used in domestic dialing.

Overlay and Future Considerations

Currently, there is no overlay code for the 813 area. The Russian numbering plan has been stable, but with the growth of telecommunication services, the Ministry of Digital Development, Communications and Mass Media periodically reviews numbering resources. As of now, no changes are anticipated for the 813 code. However, users should be aware that when dialing from a foreign country, the exit code of that country must be used before the +7. For example, from the US, you would dial 011 7 813 123-45-67.
