Can I continue to work with non-IAB vendors?  

Yes. Publishers will also still be able to work with vendors who have not committed themselves to TCF. However, TCF 2.0 stipulates that it must be clear for the user whether the vendor is from the IAB’s Global Vendor List or if it is a non-IAB vendor. For this reason, the framework recommends clearly listing both groups separately.

Do you need further help?
