If you want to add additional sub-labels to your existing Spotify for Artists label account, you will first need to get the Username and Email Address that is linked to your existing Spotify for Artists label account (found by clicking the user icon in the top-right corner of Spotify for Artists).
You will then need to contact Spotify for Artists support via their live chat, click the 'Start messaging' button, and follow the steps: Discography ➜ Label Roster ➜ Speak to an agent
You can then send the following message to the Spotify for Artists support agent, filling in the necessary information in BOLD that is relevant to your sub-label and your Spotify for Artists label account:
I have recently added an additional sub-label to my account distributed by Label Worx Limited.
The following sub-label needs to be added to my label access group. This is so that I can access the additional sub-label's deliveries made from Label Worx Limited in my existing Spotify for Artists label account.
Username: INSERT_YOUR_SPOTIFY_FOR_ARTISTS_USERNAME_HERE Email Address: INSERT_YOUR_SPOTIFY_FOR_ARTISTS_EMAIL_ADDRESS_HERE Sub-Label Name: INSERT_YOUR_EXACT_SUB_LABEL_NAME_HERE Example Track URI: INSERT_A_TRACK_URI_FROM_YOUR_SUB_LABEL_HERE These requests normally need to be escalated to another team, so please could you pass this through to the escalations team if necessary.
In most cases, the Spotify for Artists support agent will need to escalate this request, and will ask you for your email address so that their escalations team can reach you if they need any additional information.
