See the signals encoded in a consent string

Decode a TCF version 2 string using the official IAB Tech Lab core. The result shows purpose and vendor signals, CMP identifiers, dates and list versions. It does not install a consent banner or change a website's consent choices.

A string does not reveal actual tracking

These are encoded declarations. They do not prove that a website obeyed a choice, that a vendor received data, or that consent meets a legal requirement. Publisher restrictions can narrow the signals shown; this inspector reports their presence without deciding whether processing is permitted.

Vendor names come from bundled IAB Europe list 181, dated 15 October 2026. A different version can have changed or missing names; unknown IDs remain visible. The page fetches its snapshot from this site and does not contact vendors.
