Developed by the IAB’s Tech Lab, the Global Privacy Platform (GPP) is a standardized framework for storing and passing user privacy consent preferences.
AdMob supports GPP for publishers and consent management platforms (CMPs) that wish to use the framework for compliance with US privacy laws. The use of GPP or a consent management platform is not a requirement for US states with applicable privacy laws.
For ads served to users in the European Economic Area or the UK, AdMob will continue to use the IAB Europe TCF through the use of a certified Consent Management Platform. TCF strings sent through the GPP will not be accepted.
While the IAB intends to deprecate the US Privacy String by end of January 2024, in favor of GPP, AdMob will continue to read the US Privacy String in order to support apps partners. Once fully supported by AdMob, it is recommended that publishers and CMPs move forward with GPP strings, instead of the US Privacy String, if they choose to use an IAB framework for US state privacy law compliance.
Global Privacy Platform specifications
AdMob will only accept the following US States strings within GPP: California, Virginia, Colorado, Connecticut.
AdMob will not accept US National, IAB Canada TCF, US Privacy String, US States Utah, or IAB EU TCF v2.2 as part of GPP support.
Publishers should work with their CMP partners to ensure that TC strings are generated based on the IAB TCF v2.0 spec.

Consent signals for Minors using the Global Privacy Platform
The IAB’s Global Privacy Platform offers the ability for you, or your CMP, to pass relevant consent signals in response to US state privacy laws requiring additional considerations for minor and/or child-directed inventory. We recommend that publishers continue to use our tools for tagging sites, apps, and requests for child directed treatment to facilitate compliance with COPPA and other relevant regulations (AdSense, AdMob, and Ad Manager).
