You can find the vendors which can be declared at "Associated ad technology providers" in Google Ad Manager to override the EU TCF consent signals.
Google’s Additional Consent Mode allows advertisers and publishers to collect consent for vendors not covered by IAB TCF but still participating in Google’s ad ecosystem. Learn more: Google Additional Consent
The Additional Consent (AC) String is used to store user consent preferences for Google Ad Tech Providers that are not part of the IAB TCF framework.
Google’s Additional Consent works alongside IAB TCF by capturing user consent for vendors outside the standard TCF Vendor List.
Google provides a list of Additional Consent vendors who can process data under GDPR. View the latest list on this page.
An example of an Additional Consent String: 1~123,345,678. This indicates consent for specific Google Ad Tech vendors.
