The ID5 Universal ID
The ID5 ID is a neutral, universal identifier for digital advertising that can be used by publishers, brands and ad tech platforms (SSPs, DSPs, DMPs, Data Providers, etc.) to eliminate the need for cookie matching.
Publishers can activate the ID5 ID directly in Prebid.js with a simple configuration, as documented on the Prebid.org website.
Ad tech platforms that want to leverage the ID5 ID can reach out to us at firstname.lastname@example.org to learn how.
After submitting the form, we will process your request and get back to you within 1 business day with your ID5 partner number. If you have any questions, please reach out to us at email@example.com.
