YouTube Operations Guide
In some cases, Content Owners have established relationships with certain uploaders and need to protect them from automated Content ID claims. Content ID whitelisting allows for this.
If you have an agreement with a content uploader ahead of time and have cleared them to use your content, you can Whitelist them so that claims will not appear on their uploads. This is particularly important for licensed content.
For example, if you are a music label and you have licensed your music to a car company’s channel that regularly uses your music in their videos, you will want to whitelist the channel to avoid claiming their content.
Add channels to Whitelist within the "Content ID" tab of your Content Manager.
