This record is best assessed as a distributed network of FSB territorial security organs—regional directorates/departments by federal subject—rather than a single installation. Russian law defines these territorial organs as the regional and subject-level directorates/departments of the federal security authority, and the FSB’s official territorial-organs map publishes them region by region with public addresses and contact data.

As of March 2026, the official FSB map shows fixed headquarters and contact points for these offices in regional capitals, including UFSB for Moscow and Moscow Oblast at Bolshaya Lubyanka 20, UFSB for Saint Petersburg and Leningrad Oblast at Liteyny Prospekt 4, and RUFSB for Tyumen Oblast at Sovetskaya 40. The same official map also includes additional current entries such as UFSB for the Republic of Crimea and the city of Sevastopol, suggesting the supplied 76 placemarks are a substantial but not necessarily complete public roster.

The statutory mission set for FSB organs includes counterintelligence, counterterrorism, crime suppression, intelligence, border activity, and information security. Separate legal duties include informing federal and regional authorities about security threats and detecting, preventing, and suppressing foreign intelligence activity; regional departments sit within that framework as the FSB’s standing subject-level security headquarters.

Open sources do not publicly confirm detailed internal organization for most regional departments. What is publicly confirmed is that territorial organs may include subdivisions implementing core security activities plus management and support functions, and published FSB orders explicitly reference investigative sections within the Moscow and Saint Petersburg regional directorates, indicating that at least the largest metropolitan offices are multi-function headquarters with operational and case-processing capacity.

Official FSB reporting on 6 October 2025 described joint preventive actions in 75 Russian regions against administrators and users of violent online communities, showing that the regional-department network can support synchronized nationwide operations alongside the Interior Ministry, Investigative Committee, and Rosgvardiya. The same public ecosystem also assigns territorial organs an administrative role in licensing work connected with activities involving state secrets, reinforcing that these offices are permanent regional security hubs, not only ad hoc operational detachments.

In frontier subjects represented in the record—such as Belgorod, Kursk, Bryansk, Kaliningrad, Krasnodar, Primorsky Krai, and Saint Petersburg/Leningrad Oblast—the regional UFSB departments operate alongside separate FSB Border Service organs with their own published headquarters and zones of responsibility. Official border-service listings show that these boundary-facing commands do not always map one-for-one to the territorial-department roster—for example, Belgorod and Voronezh are combined for one border command—so the regional departments should be treated as only one layer of the FSB’s wider regional posture.
