What is a IPI/CAE number?

The IPI is a 9-digit identification identification number that is assigned to songwriters (and publishers) to keep track of rights.

IPI literally means “Interested Parties Information” and in 2001, it replaced the older standard called “CAE” (from Switzerland and it meant Compositeur, Auteur and Editeur).

How To Get an IPI Number

The assignment of the IPI number is done by the PRO (such as ASCAP, BMI and SESAC) whenever an artist signs up for membership.  Artists can only have 1 contract with 1 PRO at any given time.pro-logos-2

When a song is submitted via a publisher (ie, CD Baby, Tunecore, etc), the authors are identified using their IPI number and that is how royalties are tracked.

This can be easily done by searching via any of the main 3 PRO websites:
