All publishers and CMPs were required to transition to the IAB Europe's Transparency and Consent Framework (TCF) v2.3 by March 1, 2026. Failure to meet this requirement may cause the associated ad request to be defaulted to limited ads or dropped entirely, which may impact revenue.
We've introduced a new TCF error report code 1.4 to represent scenarios in which the "Disclosed vendors" section required of all TCF v2.3 strings is missing, malformed, or does not include Google. For details, visit Publisher integration with the IAB Europe TCF and Troubleshooting IAB EU TCF v2.3 implementation.
