To align with evolving industry standards for user transparency and consent, all publishers and CMPs are required to transition to the IAB Europe's Transparency and Consent Framework (TCF) v2.3 by February 28, 2026. Google’s systems can accept and process TCF v2.3 strings today. As such we recommend that you begin this transition well ahead of the deadline to avoid disruption to ad serving. For details, visit Publisher integration with the IAB Europe TCF.
