What is an IPI/CAE Number?

What’s an IPI number?

An Interested Party Information (IPI) number is a unique, international identification number, usually 9–11 digits long. IPIs are assigned to songwriters, composers and music publishers.

How are IPI numbers used?

Most of the world’s performing rights organizations use IPI numbers to link you to your musical works, so we can track performances of your music and pay royalties to the right people.

IPI numbers are helpful for distinguishing you from all the other music writers and publishers throughout the world. For example, let’s say you write a song with someone who has a common name, like Pat Smith. You can make sure you have the right Pat Smith by searching by Pat’s IPI number when you’re registering the song with ASCAP.

How do I get an IPI number?

An IPI number is generally assigned within five business days after you join your PRO. Once it’s assigned, you will find it listed in your Member account.

Please note that IPI numbers aren’t assigned by your PRO – they are assigned on

behalf of the International Confederation of Societies of Authors and Composers (CISAC).

What do I do with my IPI number?

Whenever you register your music with your PRO, make sure to include your IPI number. Send your IPI number to your collaborators, and make sure you get theirs, too. This ensures that you’re always adding the correct entitled party to your registration.

Is an IPI number the same as my PRO member ID?

No, they are two separate numbers. Your IPI number is available to the public, in connection with your name and registered music. You can share your IPI number freely – and you should share it whenever you’re collaborating with another writer or publisher. Your PRO member ID is used only for your PRO business, and should be kept confidential.

I have both a writer and publisher account with my PRO. Is my IPI number the same for both?

No, you have a unique IPI number assigned to each of your PRO account
