Buyuk Reklam Cozumleri LLC
Buyuk Reklam Cozumleri LLC is the Turkish legal entity through which Yandex provides internet services, operating AS212066 and serving as data controller under its privacy policy. Registered in the Istanbul Chamber of Commerce, it contracts directly with Turkish users and advertisers, making it the central commercial node for Yandex in Turkey.
Why It Matters
Turkish consumers and businesses are contractually tied to this entity. Alterations to its user agreement, privacy policy, or Direct offer can shift account access, data handling, billing obligations, and business visibility on Yandex Maps. Cross-border data transfers to Russia raise compliance and trust risks.
What Public Sources Show
Büyük Reklam Çözümleri Limited Şirketi, rendered in network records as Buyuk Reklam Cozumleri LLC, is the locally incorporated entity through which Yandex delivers its full internet service suite to Turkey. Registered in Istanbul’s Chamber of Commerce, it appears as the contracting party in all Turkish-facing Yandex legal instruments.
The company’s portfolio includes Yandex Search at www.yandex.com.tr, Yandex Maps, Yandex ID account services, Yandex Direct advertising, merchant tools, and Yandex Metrica/AppMetrica analytics. These applications serve Turkish consumers, advertisers, website operators, and businesses that manage organization cards on Yandex Maps.
As data controller under the Yandex Privacy Policy published in April 2026, the company determines how personal data is processed and permits transfers to Russia and other third countries. Advertisers must prepay budgets and may be asked for tax and license documents. Yandex reserves the right to moderate, restrict, or terminate access under its terms.
In public routing data, the company holds Autonomous System AS212066 (YANDEX-COM-TR), allocated in September 2025 and registered under RIPE organisation ORG-YATR1-RIPE. BGP tools show AS212066 originating IPv4 and IPv6 prefixes and peering at DE-CIX Istanbul, though observed prefix counts vary across observers.
Turkish users and advertisers are contractually and operationally bound to this entity. Any revision to the User Agreement, privacy policy, or Direct offer could alter account access, search visibility, business-listing management, billing terms, and cross-border data handling. The AS212066 routing silhouette offers a narrow but observable signal of service reachability.
What public sources do not show are equally material: there is no disclosed revenue, headcount, customer metrics, or identifiable parent-company ownership structure. No executive or manager is named in the available terms or registry filings, obscuring the locus of personal accountability.
Concrete watchpoints include the next update of the privacy policy or advertising terms, any BGP-visible change to AS212066 prefix announcements or upstream connectivity, and modifications to the Chamber of Commerce or RIPE registry entries. Each could shift the risk exposure of Turkish Yandex stakeholders.
Operating Surface
The company operates as Yandex’s local legal counterparty, providing Yandex Search, Maps, Yandex ID, Direct advertising, Merchants, and Metrica/AppMetrica analytics to Turkish users and advertisers. It is the contracting party in all Yandex Türkiye legal instruments and serves as data controller for personal data processed through its services.
The company merits monitoring because it governs Turkish user and advertiser access to Yandex services. Changes to its terms, privacy policy, or advertising contracts can directly affect Turkish digital markets, while its AS212066 routing footprint offers insight into infrastructure dependability.
Watchpoints
The company is the critical local node for Yandex's Turkish market access; its legal and routing posture shapes user and advertiser dependency. Monitoring its policy changes and routing stability can signal Yandex's strategic intent in Turkey and any regulatory pressure.
Monitor the Yandex Türkiye legal page for updated terms, privacy policy, or Direct offer. Track AS212066 for prefix changes, new peerings, or RPKI status. Watch Istanbul Chamber of Commerce for registry changes.
Revenue, advertiser count, and market share are unknown. The ownership chain within the Yandex group is not documented. No named executives are identified. Routing inventory varies by observer; authoritative prefix list and routing policy require direct BGP feeds.
