An artist ID is a unique identifier assigned to an artist to easily locate them across digital platforms. They are exceptionally important for keeping track of where releases have been delivered and also for identifying different artists who may have the same name. For example, “Rainbow” is the name of a K-pop girl group and also a Hard rock band from the UK. Without their own unique artist IDs, stores wouldn’t know which Rainbow profile was the correct page to publish each artists’ releases on.
Each platform has their own format for displaying Artist IDs. On Apple Music, artist IDs are a string of digits found at the end of an artist’s URL. Spotify Artist IDs are strings of numbers and letters found within an artist’s URL. For Audiomack, they’re a string of digits found in the artist’s profile.
