@patmmccann it will be published on the Vendor list this Thursday.
Here is also official confirmation from IAB Europe:
Congratulations, we are pleased to confirm your approved status as a registered vendor of the IAB Europe Transparency and Consent Framework (TCF). Your Vendor ID is 1345. Your ID and the information you provided for inclusion in the Global Vendor List (GVL) will be published here (note this is an automatic publishing process that currently takes place every Thursday at 17.00hrs CET).
We would appreciate if this PR could be merged to this week's release, so we could use our TCF ID right away as we have pending client implementation. Many thanks in advance!
