An IPI (Interested Party Information) number is a unique identifier assigned to songwriters, composers, and music publishers. It helps performance rights organizations (PROs) like ASCAP, BMI, or SESAC track your works and make sure royalties are paid to the correct person.
You receive your IPI number when you register as a songwriter or publisher with a PRO. It is usually listed in your account profile or alongside your name in the PRO’s public repertoire database.
In short, your IPI number is like an ID card in the music publishing world, ensuring your royalties find their way to you.
