Transferring podcast ownership on Apple Podcasts
If you are transferring ownership/management of a podcast, Apple might need you to verify this with a six-digit authorization code provided by Apple Podcasts.
To insert the six-digit authorization code in the <itunes:keywords> or <copyright> tag in your RSS feed, you'll need go to your latest uploaded track and click the edit button under the waveform. Then add the six-digit security code in the description box and save the changes. Finally, get in touch with Apple again so they can proceed.
