Consent String Decoder: FAQ

What is this site?

With the introduction of the GDPR and CCPA, marketers and advertisers have widely adopted IAB standards to communicate user consent and permission preferences. This is a simple site intended to make it easier to troubleshoot and debug consent strings.

How do you parse consent strings?

Depends on which standard!

• For TCFv1 strings, the consent-string library from the IAB is used.
• For TCFv2 strings, the tc-string-parse library from AudienceProject is used.
• For US Privacy Strings (CCPA), a custom implementation is used.

Does the IAB run this site? Do they support it?

Nope! Hopefully lowering the bar to understand consent signals is a net positive for the IAB, but there is no formal relationship.
