🟥 Action required

⚠ Risk:The TC String records consent signals; it cannot prove that the consent interface is lawful and fair. Technical compliance does not mean that all GDPR obligations have been fulfilled.

Deadline / window:October 23, 2026 [1]

What happened

According to PPC Land’s October 12, 2026, analysis, the TCF v2.4 specification and vendor list update were published on July 23. Registered consent management platforms (CMPs) must complete the new web disclosures by October 23, 2026; the deadline for apps and connected TVs is February 23, 2027. The update mainly concerns the vendor list’s standardTexts field, not the consent string’s bit layout. [1]

Seller impact

  • InferenceWebsites using TCF may need their CMP to update disclosure copy and vendor lists; checking string format alone is insufficient to confirm that migration is complete. We recommend reviewing the service provider’s implementation records over the next two weeks. Upgrade costs and specific delivery dates are unknown. [1]
  • FactGoogle has verified v2.3 since March 1, 2026. Non-compliant requests may be restricted to limited ads or discarded, affecting the availability of personalized ads. The materials do not specify penalties for missing the v2.4 deadline, so the same consequences cannot be assumed. [1]

Suggested action

If your website uses TCF, verify with your registered CMP before October 23, 2026, whether the new v2.4 web disclosures have been fully deployed.

Evidence that would disprove the assessment

  • Assessment 1：If CMP implementation records confirm that the new disclosures have been fully deployed and spot checks of the pages are consistent, the assessment that additional migration work is needed does not apply.
  • Assessment 2：If Google’s official revised announcement cancels or changes v2.3 verification and the handling of non-compliant requests, this status must be corrected.
