Apple Music

To claim a profile in Apple Music for Artists you have to do it through https://artists.apple.com/.

Any artist can log in with his Apple ID and fill out a form in which they will be asked to write the profile name they wish to claim, to select the albums associated with that profile, and to point their role in the project (artist, manager or label manager) as well.  

Apple Music will also ask to fill in the contact information as well as with the label’s / distributor’s and the manager’s and to link it at least, with one of the artists' verified profiles on Facebook or Twitter. Apple Music for Artists will verify all the information and the identity before giving access to the platform.

Spotify

To get your Spotify Artist Profile verified and to manage it yourself, you’ll need to request access to Spotify For Artists. Once you’ve done that, you’ll get the blue check on your artist profile (the hallmark of Spotify-recognized profiles).

To request access to Spotify for Artists just fill out this form by following the steps below:

1. Indicate whether you have a Spotify user account (you must have one to manage an artist profile on the platform).
2. Log in with your user account.
3. Indicate your role (artist, manager, label, etc.), your name, the Spotify user account you want to associate with the profile, and an email to send the notifications.
4. Indicate the name of the artist or the band whose profile you want to claim and verify.
5. Lastly, verify the Twitter account of the artist or the band and provide links to the website or social networking profiles.

Spotify will check the information and then the blue checkmark will be added to your profile. This is what indicates that you are a verified artist by Spotify.

Then, Spotify For Artists will allow you to change your profile and background pictures whenever you want, create playlists, and check stats as to how, how much, and where your songs are being listened to or who are your listeners, among many other interesting data. 

Moreover, you’ll be able to synchronize your profile with Songkick to show your concert dates at your profile or with Merchbar to sell your merchandising with Spotify.

You will find all the necessary information to claim your artist profile at: artists.spotify.com.

If you don't get any reply from Spotify after a month, you have to contact directly with the channel through: https://artists.spotify.com/contact.
