The Apple Artist ID is automatically assigned to each artist that is uploaded to the iTunes Store. Artists can now enter their apple IDs in our platform.
Once the songs of an artist are available on iTunes, the Artist ID can be obtained via iTunes' artist page.
Follow these steps for obtaining the Artist ID:
1) Search any album of the artist on iTunes
2) Click on artist name's link
3) The ID appears after the letters "id" in the url (in the example the ID is 262836961)
NOTE: Please, ensure that the URL you are on is the artist page, not the album page. Format: https://itunes.apple.com/us/artist/[ ARTIST NAME ]/id[ ARTIST APPLE ID ]
Entering the Artist ID in the designated field ensures that each album, single, EP or ringtone is automatically assigned to the correct artist.
This is particularly important in cases where an Artist or Band name already exist in the iTunes Store (since many artists can have the same name and pseudonym, updating and using the Artist ID is a way to avoid mixing up your catalogue with the one from another artist with a similar name).
