A designated gatekeeper is an undertaking providing core platform services that has been designated under Article 3. For scoping by service, the relevant question is narrower: which exact core platform services are listed in the designation decision or Commission case page, and which Article 5, 6, or 7 obligations apply to each listed service.
As verified on the Commission's gatekeeper portal on 24 July 2026, 23 core platform services were designated: Alphabet's Google Play, Google Maps, Google Shopping, Google Search, YouTube, Android Mobile, online advertising service, and Google Chrome; Amazon Marketplace and Amazon Advertising; Apple's AppStore, iOS, Safari, and iPadOS; Booking.com's online intermediation service; ByteDance's TikTok; Meta's Facebook, Instagram, WhatsApp, Messenger, and Meta Ads; and Microsoft's LinkedIn and Windows PC OS. Use the current portal, case page, and designation decision as evidence because the list can change.
