The US State Signals are a set of specifications for privacy strings for multiple US states that must be used in conjunction with the Global Privacy Platform (GPP). Currently specifications have been developed to support privacy signals from five US states (California, Virginia, Colorado, Utah, and Connecticut). Additional privacy strings will be developed to support additional state privacy laws taking effect in 2024 through 2026. For the latest information on supported privacy strings, see Section Information in the Global Privacy Platform github repository.
The US state strings, ready for adoption today, can be used independently in the GPP, however they are also designed to work in combination with IAB’s Multi-State Privacy Agreement (MSPA), to help companies address the challenges of managing consent signals for multiple states.
