TCF v2.3 Enforcement Began February 2026 — Is Your WooCommerce Store Compliant?
IAB TCF v2.3 enforcement began on February 28, 2026, and WooCommerce stores still generating TCF v2.2 consent strings are already running in Google Ads Limited mode — meaning no personalisation, no remarketing, and potentially more than 50% lower programmatic revenue. The new mandatory disclosedVendors segment means consent strings without vendor disclosure proof are invalid. Server-side tracking with proper legal basis maintains conversion data flow even when browser consent rejection rates reach 60-70%.
